1 Introduction The I/O Expansion (IOX) Cabinet provides additional I/O capacity for the Superdome 32, and 64 Way server. The IOX provides up to 72 Peripheral Controller Interface (PCI) slots in six 12-slot I/O chassis. Two IOX cabinets provide up to 96 PCI slots in eight 12-slot I/O chassis. There are two sizes of IOX cabinets: the 1.96-meter cabinet and the 1.6 meter cabinet.
Introduction Overview Overview Figure 1-1 illustrates a typical Superdome server and I/O cabinet installation. Shown are a Superdome 32 Way and one IOX cabinet. Figure 1-1 I/O Expansion Cabinet Shown With Superdome 64 Way Cabinet layout The IOX uses an HP modified Rosebowl rack: an RBII-D’ 19-inch cabinet.
Introduction Overview • I/O Expansion Power Chassis (XPC) • Rear Display Module (RDM) The four basic components can be further divided into controllers and functional units as shown in Table 1-1.
Introduction Overview ICE The ICE supports a maximum of two 12-slot I/O chassis. Each I/O chassis interfaces with an I/O Expansion Master I/O backplane (XMIOB) contained within an EMI enclosure and installed on the ICE tray. Figure 1-3 ICE Layout The ICE I/O tray slides forward out of the cabinet to allow access to the PCI slots. Cables are routed out of the front of the I/O chassis, underneath the chassis, and out the rear of the enclosure.
Introduction Overview The XMIOB routes necessary utilities signals from the utilities inlet connector. It also routes other utilities signals to the bridge connector. The XMIOB also has connectors to feed through REO and clock signals to the HIOB, as well as a connector and optional filter components for the chassis OL* LED signals. Chassis sheet metal and different connector sizes prevent illegal cable connection scenarios.
Introduction Overview I/O Chassis Each ICE can hold two 12-slot I/O chassis. PCI controller cards interface with cables that approach the I/O chassis from the front. Cables are attached to the PCI cards from the front of the I/O chassis. The chassis can be removed with or without extending the ICE tray. Figure 1-5 shows the I/O chassis being inserted into the ICE. Figure 1-5 I/O Chassis XUC The XUC provides utilities functions and clock distribution for components in the IOX.
Introduction Overview The XUC chassis external dimensions (excluding cosmetic panels and mounting flanges) are 119 mm (4.7 in) high by 425 mm (16.7 in) wide by 288 mm (11.3 in) deep. Figure 1-6 XUC XPC The XPC is a part of the AC-to-DC power subsystem. The AC-to-DC power subsystem comprises one or two Bulk Power Supplies (BPS) contained within one XPC.
Introduction Overview The power subsystem has n+1 redundancy for the AC-to-DC conversion and the AC inputs. AC-to-DC n+1 redundancy is achieved with two BPSs, any one of which can support the load. AC input redundancy is achieved with two single-phase AC power cords connected to dual (n+1) primary power grids, either one of which can support the load. Figure 1-7 XPC Location 60IOX012 11/17/00 A BPS is a modular, hot swappable, power supply that is installed into an XPC slot.
Introduction Overview NOTE Figure 1-8 The BPS for IOX is the same as that for Superdome.
Introduction Overview Additionally, each BPS accepts and generates control I/O interface signals from/to the Power Monitor Subsystem (PM3) assembly, which monitors and controls the power system. The PM3 detects the number and type of BPS modules present. If any of these modules fails, the PM3 may shut down the system dependent on the specific anomaly. The PM3 controls the On/Off status of the XPC +48Vdc rail.

Introduction IOX Visual Indicators IOX Visual Indicators This section outlines the visual indicators in the IOX. ICE Visual Indicators Indicators are provided on the ICE. I/O chassis Power and I/O chassis Attention LEDs are located on the center separator between the PCI card cages. The PCI Slot Power and PCI Slot Attention LEDs are located in the PCI card cage. Table 1-4 lists the visual indicators on the ICE. All indicators require some action before they can be displayed.
Introduction IOX Visual Indicators ICE Center Separator The separator in the ICE contains four LEDs: two for chassis 1 and two for chassis 3. See Figure 1-11. Figure 1-11 Center Separator If the chassis power is within the valid range, the Power LEDs are green.
Introduction IOX Visual Indicators PCI Card Separators Between each PCI card is a separator card. These cards indicate the voltage to each card. When the LED is green the voltage is within the valid range. If there is a problems, the LED is amber. See Figure 1-12. Figure 1-12 PCI Card Separators ICE Fan Status LEDs Each of the four ICE fans has a status LED. If the fan is functional the LED is green.
Introduction IOX Visual Indicators NOTE Figure 1-13 Chapter 1 There may be a delay of up to 60 seconds after turning on the 48V before the fan LEDs become active.
Introduction IOX Visual Indicators XPC visual Indicators The XPC houses two BPSs and each has a set of LEDs both on the front and rear. Figure 1-14 shows the front view of the BPSs. See Figure 1-14. Figure 1-14 BPS Front LEDs The meaning of each LED is given in Table 1-5. Table 1-5 XPC Font LED Definitions LED Definition AC0 Present On (amber) when AC is present on side A. Valid AC is line voltage is present at connector 1 AC1 Present On (amber) when AC is present on side B.
Introduction IOX Visual Indicators Front and Rear Displays IOX Control Panel Display (CPA) The CPA mounts on the front of the XUC. The CPA contains one XFPB (IOX Front Panel Board) and an attached 48V power on/off switch cable assembly. It provides a 1-1/2 digit cabinet number display (decimal), and LEDs for +5.3V Housekeeping Good and +48V Good. These are directly visible over a wide angle from the front of the IOX. The XFPB also has an ambient temperature sensor.

Introduction System Configurations Recommended Loading Order The recommended loading order of IOX components is to place the XPC as the lowest and the XUC and RDM as the highest IOX components in the rack. IOX components should occupy contiguous cabinet space. IMPORTANT Do not install any peripheral device between IOX modules.
Introduction System Configurations The required number of ICEs should be installed between the XPC and XUC/RDM. In this way, open rack space for peripherals is maximized. The recommended loading order for a 1.6m rack is shown in Figure 1-22, and the recommended loading order for the 1.96m rack is shown in Figure 1-23. Figure 1-22 1.6 Meter Rack Loading Figure 1-23 1.
Introduction System Configurations NOTE The IOX is shipped from the factory with all components installed in the recommended configuration. It should not be necessary to move components in the rack to accommodate adding an IOX (upgrade).If peripherals have been loaded, however, so that there are not 9U of contiguous rack space, it will be necessary to move peripherals to add the ICE.
Introduction System Configurations chassis in an ICE which are numbered 1 and 3 to match the numbering scheme in an I/O bay in the Superdome cabinet. XMIOBs are also numbered 1 and 3 to match the I/O chassis they serve. Figure 1-24 illustrates the logical component numbering for the IOX.
2 Upgrading the Superdome for IOX Whenever an IOX is connected to a Superdome server, the server must have special cable exit panels. These panels contain EMI proof cable clamps, called R-PEC for REO cables and U-PEC for GSP bus cables, through which these cables pass between the IOX and Superdome.
Upgrading the Superdome for IOX and Superdome require cutouts for the cables through which to pass. IOXs are shipped with skins that contain these cutouts. The “pre-IOX-release” Superdome servers require upgrading to skins with cutouts and cable exit panels. If the IOX connects to a Superdome 32 Way, you must determine to which side the IOX is connected. If two IOXs are connected to the Superdome 64 Way server, you must upgrade both cable exit panels. An IOX can also be connected to a Superdome 64 Way.
Upgrading the Superdome for IOX Removing Old Side Skins Removing Old Side Skins Step 1. Power down the Superdome server. Step 2. Remove the side (the on to which the IOX is to be connected) and rear blower bezels on each server cabinet. Figure 2-1Removing Blower Bezels NOTE Perform the following step only if installing the IOX on the rear-door-hinge side of the Superdome server. Step 3. If the rear door must be removed, perform the following steps. Otherwise, skip this step and go to Step 4.
Upgrading the Superdome for IOX Removing Old Side Skins 1. Remove the cable connected to the rear display cable located on the rear door, as shown in Figure 2-2. Figure 2-2Removing the Rear Display Cable 2. Remove the door grounding wire from the back channel, as shown in Figure 2-3.
Upgrading the Superdome for IOX Removing Old Side Skins NOTE The ground wire and/or connection point on your cabinet may be different to that shown in the figure. Figure 2-3Removing Rear Door Grounding Wire 3. Remove the rear door. Turn the door inward and lift it off its three hinges.
Upgrading the Superdome for IOX Removing Old Side Skins NOTE The door can only be lifted off the hinge pins by turning it inward as if you were partially closing it.

Remove the T20 screws that secure the side skin(s) to be removed. Figure 2-6 shows the left side skin (as viewed from the front of the server).
Upgrading the Superdome for IOX Removing Old Side Skins Step 5. Remove the appropriate side skin by sliding them out toward the back of the cabinet. See Figure 2-7.
Upgrading the Superdome for IOX Installing New Cable Exit Panel Installing New Cable Exit Panel Step 1. Remove old cable exit panel(s) on the appropriate side(s) of the Superdome cabinet. Both the left and right exit panels are shown in Figure 2-8. The exit panels are secured with two T20 Torx screws. Figure 2-8Removing Old Exit Panels Step 2. Remove the rear door latch from the old blank EMI panel and install it on the new panel.
Upgrading the Superdome for IOX Installing New Cable Exit Panel Step 3. Install the new cable exit panels into the appropriate side(s) of the panel. Secure the panel(s) with two T20 Torx screws. See Figure 2-9.
Upgrading the Superdome for IOX Installing the New Side Skins Installing the New Side Skins The new side skin(s) must be installed after the new exit panel(s). The Superdome side skin required for an IOX has a cutout that lines up with the cable feed clamps (R-PECs and U-PECS) in the new cable exit panel(s). Step 1. Locate the new side skin(s), remove it from the cardboard shipping container and remove the protective plastic wrap from the new side skin(s).
Upgrading the Superdome for IOX Installing the New Side Skins Step 2. Install the new side skin(s) in place of the old one(s). Install two T20 Torx screws at the top and bottom of the back of the side skin to secure.
Upgrading the Superdome for IOX Finishing the Upgrade Finishing the Upgrade Once the new exit panels are installed, the rear door (if removed), and blower bezel(s) must be reinstalled onto the Superdome cabinet(s). Perform the preceding procedures in reverse. Reinstalling the Rear Door NOTE Perform the following steps only if you had to remove the rear door to the Superdome cabinet. Step 1.

Installing the IOX Unpacking the IOX Step 7. Remove the anti-tip stabilizer feet located under the front of the IOX by loosening the two shipping bolts using a 13-mm socket. This task may require a ratchet extension as the bolts are approximately 14 inches from the edge of the IOX. See Figure 3-6, Figure 3-7, and Figure 3-8.
Installing the IOX Unpacking the IOX Figure 3-8Removing the Anti-Tip Stabilizer Feet Step 8. Remove the power cord from the cabinet back rail by cutting the green tie-wraps on the rail and removing the green VELCRO ties holding the cord. NOTE Green tie-wraps and green VELCRO ties secure the cables during shipment. They should be removed when installing the IOX. The black tie-wraps and VELCRO ties should not be removed.
Installing the IOX Unpacking the IOX Step 9. Using the 13-mm socket and ratchet wrench, remove the four pallet securing brackets. Two are located toward the front of the cabinet, and two are located at the rear behind the anti-tip stabilizer feet. The anti-tip stabilizer feet must be removed (and are removed in Step 7. ) before these two pallets bolts can be removed. See Figure 3-10.
Installing the IOX Moving the IOX into Position Moving the IOX into Position After removing the packing materials, the pallet securing bolts, and the ramps, you are now ready to move the IOX into position. Step 1. Place the ramps onto the pallet. There are two slots in the wooden pallet into which the hooked ends of the ramps fit. The hooks and slots keep the ramps from sliding off the pallet while rolling the cabinet down the ramps.
Installing the IOX Moving the IOX into Position Step 2. Remove the middle side panels to expose the rack channels and rails. This allows you to grip firmly the IOX as you roll it down the ramps. Figure 3-12Remove Side Panels Before Rolling Cabinet onto Ramps Figure 3-13Exposing the Channels and Rails Step 3. While holding one of the side rails with one hand and the cabinet front with the other, carefully roll the IOX cabinet down the ramps. Two people are required to do this task. See Figure 3-14.
Installing the IOX Moving the IOX into Position WARNING Do not stand in front of the IOX while it is rolled down the ramps. It can fall on and injure you. WARNING Do not attempt to move the Superdome cabinet, either packed or unpacked, up or down an incline of more than 15ο. CAUTION Make sure that the leveling feet on the rack are raised before you roll the rack down the ramp and any time you roll the rack on the casters. CAUTION Use two people when rolling the cabinet down the ramps. Step 4.
Installing the IOX Aligning the IOX Cabinet to the Superdome Cabinet Aligning the IOX Cabinet to the Superdome Cabinet The IOX can be installed on either side of a Superdome server. Both the Superdome and the IOX cabinets, therefore, have pass-through cutouts that are covered by panels. Located on each side of the rack, these cutouts allow the IOX to be installed on either side of the Superdome cabinet. Figure 3-15 shows the panel removed in a Superdome server.
Installing the IOX Aligning the IOX Cabinet to the Superdome Cabinet NOTE Figure 3-16 Chapter 3 There are no mechanical features that hold the superdome and IOX in alignment.

Installing the IOX Aligning the IOX Cabinet to the Superdome Cabinet Step 2. Remove the IOX exit panel blank on the side that is to be next to the Superdome server.
Installing the IOX Aligning the IOX Cabinet to the Superdome Cabinet Step 3. Install the IOX so that the front surface of the IOX side panel is in line with the front surface of the superdome side skin, as shown in Figure 3-19. Figure 3-19IOX Cabinet Alignment (Front) Step 4. Ensure that the cutout in the IOX rack extension panel aligns with the Superdome cable exit panel as shown in Figure 3-20.
Installing the IOX Securing the Cabinet Securing the Cabinet Step 1. Once in position, secure and stabilize the cabinet using the leveling feet at the corners of the base using the 13-mm open-end wrench. Remove the shipping band before adjusting the leveling foot. Figure 3-21Leveling Feet Step 2. Attach the anti-tip panels at the front and rear of the cabinet using the 13-mm socket and ratchet wrench.
Installing the IOX Securing the Cabinet Before attaching the front foot, be sure to mount the kick panel mounting bar as shown in Figure 3-22. The same screws that secure the anti-tip panel pass through the kick panel mounting bar. Figure 3-22Attaching the Anti-Tip Stabilizer Feet Step 3. Attach the kick panel at the base of the cabinet front as shown in Figure 3-23.
Installing the IOX Connecting the IOX to the Superdome Connecting the IOX to the Superdome Grounding the IOX to the Superdome After the IOX has been moved into place, it has to be grounded to the Superdome next to it. Provided with the IOX is a grounding cable with lugs on both ends. The following procedure describes how to connect the grounding cable. Step 1. Locate the grounding cable and determine which side of the rack to secure it. Figure 3-24IOX Grounding Strap Step 2.
Installing the IOX Connecting the IOX to the Superdome There are two lugs for this in both the IOX and Superdome server: one on either side of the cabinet. Secure the cable on to the side nearest the IOX. Figure 3-25Ground Studs in Superdome Cabinet Connecting the REO and GSP Bus Cables Overview The IOX is shipped with all cables connected.
Installing the IOX Connecting the IOX to the Superdome IMPORTANT Do not remove any black or grey cable ties. Figure 3-26 Remove and Discard Green VELCRO Ties There are optional brackets for retaining cables in the cable routing channel at the rear of the extension and additional holes for attaching cable ties in the routing channel.

Installing the IOX Connecting the IOX to the Superdome There are two REO cables per ICE, and therefore REO cables are always connected in pairs. There are four R-PECs and one U-PEC in the cable exit panel. The REO cable pairs from the ICE mounted lowest should mount and run through the bottom R-PEC in the cable exit panel. Likewise, the REO cables from the next higher ICE pass through the next higher R-PEC, and so on.
Installing the IOX Connecting the IOX to the Superdome Step 2. Remove the rear door of the Superdome server. Step 3. Cut the green tie wraps and remove the green VELCRO ties holding the REO cables during shipment. NOTE The IOX may have one, two, or three ICEs. There are two REO cables per ICE. Therefore, you may have to perform these steps on as many as three REO cable pairs. Step 4. Remove the appropriate R-PEC from the cable exit panel by loosening the two T15 Torx screws.
Installing the IOX Connecting the IOX to the Superdome Step 5. Determine the destination in the Superdome server of the REO cable and pass the REO cable pair through the cable exit panel where the R-PEC was removed. Figure 3-33Passing the REO Cable Pair Through the Superdome Cable Exit Panel Step 6. Determine which shield protector to remove and pull the perforated section. Discard the plastic. The shield is exposed after the protector is removed. See Figure 3-34.
Installing the IOX Connecting the IOX to the Superdome IMPORTANT Remove the protective plastic only on the appropriate shield section. Leaving the other shield section exposed can cause inadvertent shorting. Figure 3-34REO Shield Exposed Step 7. Separate the halves of an R-PEC. You will have to loosen the screws in the blanks to facilitate their removal. The R-PEC attaches to the exposed shield in the REO cable. There are two halves that fasten together with three T15 Torx screws.
Installing the IOX Connecting the IOX to the Superdome IMPORTANT The R-PEC blanks must occupy all unused holes.
Installing the IOX Connecting the IOX to the Superdome Step 8. Attach the REO cable R-PEC to the cable at the exposed shield using two T15 Torx screws. See Figure 3-36. Figure 3-36Installing the R-PEC Step 9. Install the R-PEC in the appropriate location on the cable exit panel using two T20 Torx screws.
Installing the IOX Connecting the IOX to the Superdome IMPORTANT The three screws need to be tightened in the following sequence: middle first, then one side, and then the other side. Tighten each screw one turn at a time, repeating the sequence until all three are hand tight. This tightens the clamp onto the cable without warping. Figure 3-37REO Cable Pair Mounted in R-PEC and Installed in Cable Exit Panel Step 10. Connect the REO cable to the appropriate Cell board connector in the Superdome server.
Installing the IOX Connecting the IOX to the Superdome Step 11. Repeat Step 4. through Step 10. for each REO cable pair. Figure 3-38Typical REO Cable Locations Connecting the GSP Bus Cables The GSP bus cables are very similar to the REO cables, in that they have two sections where the shield is exposed. They are routed they same way as the REO cables and are secured to the Superdome cable exit panel with a U-PEC (as opposed the R-PEC used for the REO cables).
Installing the IOX Connecting the IOX to the Superdome Step 2. Remove the GSP bus U-PEC from the cable exit panel by removing the two T15 Torx screws. See figure Figure 3-40. In the figure the IOX is not in place for illustrative purposes. Figure 3-40Removing the GSP Bus U-PEC Step 3. Pass the GSP bus cable through the cable exit panel. Figure 3-41Passing the GSP Bus Cable Through the Cable Exit Panel Step 4. Determine which shield protector to remove and pull the perforated section.
Installing the IOX Connecting the IOX to the Superdome NOTE Remove the blue shield protector when the destination server is next to the IOX. Remove the green shield protector when the destination server is not next to it, as with a Superdome 64 Way server. IMPORTANT Remove the protective plastic only on the appropriate shield section. Leaving the other shield section exposed can cause inadvertent shorting. Figure 3-42GSP Bus Cable Shield Protector Step 5.
Installing the IOX Connecting the IOX to the Superdome IMPORTANT The U-PEC blanks must occupy all unused holes. Figure 3-43U-PEC Step 6. Attach the U-PEC to the GSP bus cable where the shield is exposed and tighten the two T15 Torx screws. Tighten the blank screws to seat the gasket.

Installing the IOX Setting the Cabinet Number Setting the Cabinet Number After installing the IOX, the cabinet number must be set. The IOX cabinet is either 8 or 9. to set the cabinet number: Step 1. Remove the XUC bezel by holding it with both hands on the handles on the side of the bezel and pulling forward. This exposes the XUC front panel. There are two latch screws on either side of the panel. Figure 3-48XUC Cosmetic Bezel Step 2. With a slotted screwdriver, turn the latch screws counter-clockwise.
Installing the IOX Setting the Cabinet Number Step 5. Locate the Cabinet Number switch and set it to the appropriate number. Figure 3-50Cabinet Number Switch IMPORTANT Never have two IOX cabinets the same number. IOX cabinets can either be 8 or 9. If you have two IOX cabinets for a Superdome 64 Way server, then the numbers needs to be 8, then 9, respectively. Step 6. Close and lock the XUC front panel. The magnetic latch holds the panel in the up position. Lower the CPA until it latches. Step 7.
4 Cabling The IOX is shipped normally with all cables already connected, but because there may be some installations that require additional cabling (as for I/O and ICE upgrades) or may have to be recabled in part or entirely, this section covers how IOX cables are installed and managed.
Cabling Cable Management Cable Management The IOX provides a large amount of additional I/O for the Superdome systems. The number and weight of the cables within the IOX is large. Cable management hardware is provided at several points in the ICE. • A wire former (or “potato masher”) provides strain relief for external I/O cables at the front of the I/O chassis. The cables are tied to this former. • The cables are routed to the back of the ICE in a space between the I/O chassis and the ICE tray.
Cabling Cable Management • All other interconnect cable connections are done at the ICE rear bulkhead.
Cabling Routing the Cables Routing the Cables Routing the cables is a significant task in the installation process. It is important not only for the immediate need of completing the installation, but efficient cable routing is important when future service calls are made. Neatness counts. The most efficient use of space is to route cables so that they are not crossed or tangled. Use the procedures in the following sections as guidelines to route cables out of the IOX cabinet to the Superdome cabinet.
Cabling Routing the Cables Under and between the I/O chassis is a cable routing trough shown in Figure 4-2. The trough provides a clear path from the front of the ICE to the rear, allowing the cable to be routed without getting caught or snagged on exiting cables. the cable puller is stored under the cable trough.
Cabling Routing the Cables Figure 4-3 88 Alternating the I/O Cable Bundles Chapter 4
Cabling Routing the Cables Step 1. For every PCI controller in the I/O chassis, route each cable from the back of the IOX, into the cable routing trough under the I/O chassis, though the cable groomer (also know as “potato masher”) (See Figure 4-4), and connect it to the appropriate PCI controller. Figure 4-4I/O Cables Connected to PCI Controllers Step 2. Feed the cable from the back over the roller cable management arm (see Figure 4-1) to the base of the tray. Step 3.
Cabling Routing the Cables Step 8. When all I/O cables have been routed to the front of the PCI chassis and secured to the potato masher, neatly bundle them using tie wraps. Secure the to the cable bundle bracket using the tee-bar and cable ties. See Figure 4-5. Use VELCRO ties to bundle cables.
Cabling Routing the Cables Step 9. Use channel brackets, tie slots, and tie-wrap anchors to secure cables that run along the rack channels. Figure 4-6IOX Channel Bracket Routing the Rear ICE Cables The rear ICE cables include: • SBA (or REO) • Clock • Utilities • Fan control • DC Power Step 1. Run all the cables listed above over the roller management arm. Step 2. Insure that all cables have sufficient service loop. Step 3. Secure each cable to the roller management arm with VELCOR cable ties.
Cabling Routing the Cables Step 5. Determine how each cable will run from the ICE tray to its destination and secure them appropriately. Figure 4-7 shows the rear ICE cables secured to the cable management hardware at the back of the ICE.
Cabling Routing the Cables Step 2. Run the cables down through the rack channels securing them to the IOX channel brackets using tie wraps or VELCRO ties. Figure 4-8 XUC Connectors Figure 4-9 Typical Cables Connected to XUC XPC Cable Routing The XPC provides the power for the other units in the IOX (ICEs and XUC). There are up to four DC power cables running from the XPC. These cables are secured to the back rack brace with tie wraps.
Cabling Routing the Cables The XPC also has one power control cable coming from the XUC. It can be bundled and routed with the power cables.

Adding an ICE to the IOX Connecting the Cables Connecting the Cables All internal ICE cables are connected prior to shipping the ICE. The ICE has several external cable connections on the backplane. You will have to connect the following cables: • REO • ICE-to-XUC clock • Fan Control • DC Power • ICE Utilities • I/O cables from the I/O chassis Removing the Fan Shield Before the ICE cables can be installed, you must remove the fan shields covering the XMIOBs. Step 1.
Adding an ICE to the IOX Connecting the Cables Step 2. Remove the fan shields to access the clock and REO cable connectors by loosening the four T10 Torx screws on each shield (two per ICE).
Adding an ICE to the IOX Connecting the Cables Figure 5-11 shows the location of connectors and mounting holes for cables to be attached in this procedure. In the figure no tables are shown. The ICE, however, is shipped with tables identifying each connector. Figure 5-11 NOTE ICE Connector Locations When viewed from the rear (as in Figure 5-11), the REO for XMIOB1 is on the left and the REO for XMIOB3 is on the right. The REO cables cross over each other inside the ICE.
Adding an ICE to the IOX Connecting the Cables NOTE Each REO cable has two connectors (input and output) that attach to each XMIOB. There are two XMIOBs per ICE, one for each I/O chassis, but you may only have one I/O chassis, and therefore, will only connect one pair of connectors to one XMIOB. Step 2. Pass the cables over the cable management arm, under the cable strain relief arm, and run the connectors through the appropriate REO ferrule mounting hole(s).
Adding an ICE to the IOX Connecting the Cables Step 4. Push the ferrule(s) up to the mounting hole(s) and secure with four screws supplied. Figure 5-13REO Cable Ferrule Mounted in ICE Step 5.

System Specifications Electrical Specifications Electrical Specifications This section provides electrical specifications for the IOX cabinet. AC Power Requirements The operating input voltage range is 176-264 VAC rms at line frequencies of 47-63 Hz. The XPC accepts one or two single phase inputs. The nominal input voltage range is 200-240 VAC rms. Table A-5 lists the AC power requirements for a IOX cabinet.
System Specifications Electrical Specifications XPC The XPC accepts one or two AC inputs as shown in Figure A-4 Figure A-4 AC Connections on XPC DC Power Requirements Each BPS is capable of 48VDC at 2800W and 5.3VDC at 65W. The 48-volt supply is referred to as PS1 and 5.3-volt supply is referred to as PS2 or 5VHK. The BPSs uses an internal schottky diode in each output in order to isolate a failed output from the XPC output voltage bus.
System Specifications Environmental Requirements Environmental Requirements This section provides the environmental, power dissipation, noise emission, and air flow specifications for the IOX cabinet. Temperature and Humidity Specifications Ambient intake air temperature is often different from ambient room temperature; measure the operating temperature and humidity directly in front of the cabinet cooling air intakes rather than check only ambient room conditions.
System Specifications Environmental Requirements • Btu/hour divided by 12,000 = tons of refrigeration required.
B Site Requirements Careful site planning and preparation ensures trouble-free installation and reliable operation of IOXs. Factors that may contribute to less than optimal equipment operation are also highlighted.
Site Requirements Space Requirements Space Requirements This section contains information about space requirements for a IOX cabinet. This data should be used as the basic guideline for space plan developments. Other factors, such as airflow, lighting, and equipment space requirements must also be considered. Delivery Space Requirements There should be enough clearance to move equipment safely from the receiving area to the computer room.
Site Requirements Space Requirements Alignment with SuperDome Cabinet The IOX will be installed so that the front surface of the IOX is in line with the front surface of the Half Dome, as illustrated in Figure B-1. Figure B-1 IOX Cabinet Footprint Next to superdome Cabinet Operational Space Requirements Other factors must be considered along with the basic equipment dimensions. Reduced airflow around equipment causes overheating, which can lead to equipment failure.
Site Requirements Space Requirements • Storage racks for tape reels, disk packs, and printer paper • Cabinets for cleaning materials • Maintenance area and spare parts 204 Appendix B
Site Requirements Power Requirements Power Requirements In general, a well-designed power distribution system exceeds the requirements of most electrical codes. A good design, when coupled with proper installation practices, produces the most trouble-free operation. A detailed discussion of power distribution system design and installation is beyond the scope of this document.
Site Requirements Power Requirements • To avoid nuisance tripping from load shifts or power transients, circuit protection devices should never be run above 80% of their root-mean-square (RMS) current ratings. • Safety agencies derate most power connectors to 80% of their RMS current ratings. Power Quality This equipment can operate over a wide range of voltages and frequencies. It has been tested and shown to comply with EMC Specification EN50082. However, damage can occur if these ranges are exceeded.
Site Requirements Power Requirements Wire Selection Use only copper conductors instead of aluminum, as aluminum’s coefficient of expansion differs significantly from that of other metals used in power hardware. Because of this difference, aluminum conductors can cause connector hardware to work loose, overheat, and fail. Raceway Systems Raceways (electrical conduits) form part of the protective ground path for personnel and equipment.
Site Requirements Power Requirements Power distribution systems consist of several parts. Hewlett-Packard recommends that these parts be solidly interconnected to provide an equipotential ground to all points. The IOX and Superdome are safety grounded through the green (ground) wire in each AC power cord. In the IOX, this ground passes through the AC power cord entry into the XPC and connects internally to the XPC chassis.
Site Requirements Power Requirements Wiring connections must be properly torqued. Many equipment manufacturers specify the proper connection torque values for their hardware. Ground connections must only be made on a conductive, nonpainted surface. When equipment vibration is present, lockwashers must be used on all connections to prevent connection hardware from working loose.
Site Requirements Facility Characteristics Facility Characteristics This section contains information about facility characteristics that must be considered for the installation or operation of a IOX cabinet. Facility characteristics are: • Floor loading • Windows • Altitude effects Floor Loading The computer room floor must be able to support the total weight of the installed computer system as well as the weight of the individual cabinets as they are moved into position.
Site Requirements Facility Characteristics Table B-1 Floor Loading Terms (Continued) Term Definition Live load The load that the floor system can safely support. Expressed in lb/ft2 (kg/m2). Concentrated load The load that a floor panel can support on a 1-in2 (6.45 cm2) area at the panel’s weakest point (typically the center of the panel), without the surface of the panel deflecting more than a predetermined amount.
Site Requirements Facility Characteristics Altitude Effects Many tape drives, including those supplied by Hewlett-Packard, have vacuum column transport mechanisms that are affected by atmospheric pressure. Adjustments to these mechanisms may be required to compensate for the lower atmospheric pressure at higher altitudes. Hewlett-Packard field engineers make these adjustments on tape drives supplied by Hewlett-Packard. Tape drives supplied by other vendors should be adjusted by the appropriate vendor.
Site Requirements Safety Considerations Safety Considerations Before proceeding with any installation, maintenance, or service on a system which requires physical contact with electrical or electronic components, be sure that either power is removed or safety precautions are followed to protect against electric shock and equipment damage. Observe all "WARNING" and "CAUTION" labels on equipment. All installation and service work must be done by qualified personnel.
Site Requirements Environmental Requirements Environmental Requirements The following environmental elements can affect an IOX installation: • Computer room preparation • Cooling requirements • Humidity level • Air conditioning ducts • Dust and pollution control • Electrostatic discharge (ESD) prevention • Acoustics (noise reduction) Computer Room Preparation The following guidelines are recommended when preparing a computer room for a IOX system: • Locate the computer room away from the ext
Site Requirements Environmental Requirements • Reheating • Air distribution • System controls adequate to maintain the computer room within the operating ranges listed in Lighting and personnel must also be included. For example, a person dissipates about 450 BTUs per hour while performing a typical computer room task. At altitudes above 10,000 feet (3048 m), the lower air density reduces the cooling capability of air conditioning systems.
Site Requirements Environmental Requirements The following three types of air distribution system are listed in order of recommendation: • Underfloor air distribution system—Downflow air conditioning equipment located on the raised floor of the computer room uses the cavity beneath the raised floor as plenum for the supply air.
Site Requirements Environmental Requirements Figure B-5 on page 220 illustrates a typical computer room above ceiling ducted air distribution system (DRA).

High humidity causes galvanic actions to occur between some dissimilar metals.
Site Requirements Environmental Requirements CAUTION Low humidity contributes to undesirably high levels of electrostatic charges. This increases the electrostatic discharge (ESD) voltage potential. ESD can cause component damage during servicing operations. Paper feed problems on high-speed printers are usually encountered in low-humidity environments. Low humidity levels are often the result of the facility heating system and occur during the cold season.
