Four-post brackets Two rivets on each bracket secure it to the brace and the server’s cover. Four-post braces These two long, U-shaped pieces support the back of the server and attach it to the rack. Two-post brackets These two short, L-shaped brackets attach to the sides of the server’s enclosure and to the rack. Screws for attaching brackets and braces to the rack and server cover Two sets of screws are provided; one set (English) has a diameter of 10/32 inches; the other is metric size M5.
C H A P T E R 2 2 Preparing to Install Your Server Before you install the server in a rack, you should carefully consider the placement of the unit in its rack and several factors in the infrastructure that will keep the server operating efficiently.
m The server slides out of the rack from the front. Be sure to leave a minimum of 36 inches clear in front of the server to allow room to open and service it. m To provide access to the server’s back panel and cables, leave at least 24 inches clear behind the server. m If you are installing multiple servers or other components in the rack, place the server so that you can easily open and service it.
Operating Environment The operating environment for the server’s rack must meet certain requirements: m Verify that the temperature range of the rack’s location is within the limits established for the server and all other components. m Make certain that the rack’s location has adequate ventilation to maintain the necessary temperature range. This is particularly important for a rack that is enclosed in a cabinet.
Security Whatever the location of the server and rack, it should be secure. m Determine that the rack’s location is secure and that only authorized staff members or technicians can gain access to this site. m If using a server cabinet that is not stored in a secure room, be sure that the cabinet has adequate locking and that access to it is limited to authorized staff.
C H A P T E R 3 3 Installing Your Server in a Rack Xserve is specifically designed for rack mounting. It is not designed for use as a desktop machine. Warning Do not place a monitor on the server or use the top of the server as a shelf in the rack. Any weight on the server’s enclosure could damage the components inside.
Installing the Server As noted previously, you can install the server in a four-post or a two-post rack. Instructions for both procedures are given below. Preparations for installing are the same, whichever type of rack you use. Important Check the documentation for your rack for any special requirements. Get Ready to Install Before beginning work with the server and rack, make the following preparations.
Some racks have marks at regular intervals (such as 1U) to aid in locating a server; others may provide a template to help place the server in the rack. If your rack does not have such aids, measure or count holes from an established point. Identify the appropriate holes in all mounting posts before you install the server so that it is mounted level. The distance between holes may vary somewhat on racks made by different manufacturers.
3 Remove the protective faceplate from the server’s front panel by unscrewing the thumbscrews at each side of the faceplate and lifting it off. Set the thumbscrews aside. Protective faceplate Remove the four thumbscrews that hold the protective faceplate in place, and remove the faceplate by lifting it straight up. 4 Loosen the two thumbscrews (one on each side) at the front of the server’s enclosure.
5 Remove the cover of the server’s enclosure by sliding it toward the back of the unit. Hold the front thumbscrews to keep the main part of the server in place as you slide the cover toward the back. With the server resting on a flat, clean, and stable surface, slide the cover completely to the rear. Press these two latches to release the cover from the server and remove it.
7 If necessary, install any optional internal components, such as additional memory or a PCI card, in the server. Follow the appropriate instructions in Chapter 5, “Installing or Replacing Server Components,” on page 49. PCI card slots (2) PCI/AGP card slot RAM slots (4) 8 If necessary, install any additional Apple Drive Modules in the front panel of the server. Follow the instructions in “Installing or Replacing an Apple Drive Module” on page 50.
Note: When installing a drive module for the first time, remove the blank drive module and save it for possible future use. This unit is necessary for appropriate cooling of the server in a drive bay that has no drive module in it. When you’ve installed optional items, you’re ready to connect the server to the rack. If you have a four-post rack or cabinet, proceed to the next section, “Install the Server in a Four-Post Rack or Cabinet” on page 29.
Once you’ve marked the exact position for the server on the rack, you’re ready to attach the server. Here is an overview of the procedure. m Connect the cover of the server to the front of the rack. m Assemble the rear mounting hardware. m Connect the rear mounting hardware to the server enclosure. m In a four-post rack, install the cable-management arm. m Slide the server into the cover and secure it. Follow these steps to attach the server to the rack.
2 Screw the flanges at the front of the cover to the front rails of the rack Be careful not to overtighten the flange screws. Doing so could change the shape of the cover slightly and make it difficult to slide the server into the cover. Attach the cover to the two front rack mounting posts using four of the screws provided. Some racks have prethreaded holes and some have square holes that take clips with attached nuts.
3 At the back of the server, position the small bracket inside the server’s cover so that the head of one rivet is facing the side of the cover. Note: Start on the left side of the server (when facing the back). This makes installing the cable-management arm more efficient. 4 Push the rivet head through the hole that’s near the back on the side of the cover. Install the brackets on the inside of the top cover. The forward rivet on each bracket must pass through the hole in the cover.
7 Slide the brace forward or backward so that the flat end of the brace is flush with the back rail of the rack and screw the brace’s flange to the rail. Note: If you are installing the cable-management arm and your server is the same depth as your rack (or within an inch of it), only attach the brace to the rail on the left side of the server (as you face the back panel). You attach the cable-management arm along with the brace at the right rear of the server.
Attach the Cable-Management Arm to the Rack 1 If the rear rails of your rack are flush with the server’s back panel or within an inch of it, position the cable-management arm so that the short side is closer to the server’s back panel and the holes on the long side align with the holes on the brace on the right side. Place the cable-management arm over the U-shaped brace, and secure both to the rack with two of the screws provided.
2 Hold the cable-management arm with the long end closer to you and fold the hinged section of the long end away from you. The hinged section is the part from which you removed the clamp and screw. This section should be perpendicular to the main part of the arm, with the oval holes furthest from you. Mount the cable-management arm as close to the back of the server as possible. Rotate the mounting plate on the arm so that it lies against the inside of the U-shaped bracket.
Place the Server in the Rack Once you’ve attached the cable-management arm, you can put the server into the rack. 1 At the front of the rack, lift the server to the level where the enclosure’s cover is installed and slide the server into the cover. Insert the server into the cover and slide it all the way back. 2 Secure the server in the rack by tightening the thumbscrews on the front. Tighten the two thumbscrews to secure the server in the rack.
4 If you’ve installed the server in a cabinet, replace and close the cabinet door. Once the server is secured in the rack or cabinet, you can attach cables for the server’s connections. See “Connect Cables to the Server” on page 40 for details of connecting cables and using the cable-management arm. Install the Server in a Two-Post (Telco) Rack The server attaches to a two-post rack at the center of the enclosure, so that the front and back of the server extend beyond the rack.
1 Attach the small L-shaped brackets to the sides of the server enclosure’s cover with four of the screws provided. Attach the two telco mounting brackets to the server’s cover using the four screws provided. Orient the bracket so that the screws are at the top. Attach the brackets to holes that are about one-third of the way back from the front panel. 2 Position the cover in the rack at the desired location and screw the flange of the L-shaped bracket to the front of the rack on each side.
3 Lift the server to the level where the cover is installed and slide the server into the cover. Insert the server into the cover and slide it all the way back. 4 Secure the server in the rack by tightening the thumbscrews on the front. Tighten the two thumbscrews to secure the server in the rack. To secure the drive modules in the server, use the enclosure key to lock them in place.
Connect Cables to the Server Once the server is secured in the rack, you can connect the cables and power cord to its back and front panels. If you use the cable-management arm, your cables must be approximately 3 feet longer than the distance between the server and its peripheral devices. This extra length may not be feasible for some cables, such as SCSI cables. In this instance, you can bypass the cable-management arm with a shorter cable. But you must disconnect that cable when you open the server.
4 Arrange all the cables on the back panel in the cable-management arm and secure them with the straps provided with the cable-management arm. The cable-management arm can only be used with a four-post rack or cabinet. If you are not using the cable-management arm, skip this procedure. It’s a good idea to group the cables and arrange them so that they don’t cause any hazard and are easy to handle should you need to detach them when opening the server.
6 Attach the power cord’s retainer clip to the back panel to keep the power cord in place when you open the server. The ends of the clip fit into the small openings at either side of the power socket. Be sure that the rounded part of the clip goes under the cord, so that the cord is supported. Attach the power cord retainer clip to the two loops on the back of the server. Snap the cord into the clip so that it cradles the cord.
9 After all connections are complete, plug the power cord into a power source. This equipment is intended to be electrically grounded. Your server is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin. This plug will fit only a grounded AC outlet. This is a safety feature. If you are unable to insert the plug into the outlet because the outlet is not grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet.
C H A P T E R 4 4 Using Your Server When you’ve connected the cables and peripheral devices you plan to use with your server, you can turn it on and set up the software and network services. Starting Up the Server Press the power button at the left side of the server’s front panel to turn it on. Power button The power indicator light turns on, and the server starts up. Status lights on the front panel indicate network connection, system activity, and drive module use.
Monitoring Status Lights and Other Indicators on the Server The server has a number of built-in sensors that detect and report essential operating factors, such as power, temperature, and condition of several key components. You can monitor the server’s operation using the lights on the unit or using the remote monitoring tools. The server’s status lights are listed in the table below.
If you have access to the server itself, you can use the buttons on the front panel to change the server’s status. These buttons include m Power: Press to turn the server on. m System identifier: This light helps you determine which server in a multiple-server rack has a problem. The light turns on when the server has a problem; it can also be turned on manually. Pressing the button next to this light turns the light off when it’s on. (Duplicates of the button and light are on the back panel.
C H A P T E R 5 5 Installing or Replacing Server Components Your server is designed so that you can install or exchange drive modules while the server is operating. The server should be turned off before opening it to install or exchange other key components. When working with the server hardware, always guard against static electricity, which can damage electronic components. Touch a metal surface before handling RAM or an expansion card or working inside the server.
When installing components, it’s wise to wear a wrist grounding strap that prevents static electricity from discharging into electronic components. It is good practice to use an antistatic wrist strap when accessing the interior of the server. You can also arrange for an Apple-authorized service provider to install or replace components in the server. For details about this service, see the support information that came with your server.
2 Remove the blank drive module or the drive currently installed. m If there is no drive installed, press the handle on the front of the blank drive module so that the handle pops out, then pull the blank drive module out of the front panel. Remove the blank drive module from the bay. m If there is a drive module already in the bay: a Make sure the drive currently in the bay is not being used by any application and that the drive is not being shared by the server.
c Wait for the upper disk light to go off, then grasp the handle and pull the drive module out of its bay and set it aside. Pull the server drive module out of the server. 3 Press to open the handle of the replacement drive module and slide it into the empty bay until its connector clicks into place. 4 The disk status light turns green to indicate normal operation. Be sure to save the blank drive module if you removed one.
3 Touch the metal enclosure to discharge any static electricity. Always do this before you touch any parts, or install any components, inside the computer. To avoid generating static electricity, do not walk around the room until you have finished installing the expansion card, memory, or internal storage device and have closed the computer. Important 4 Unplug the power cord.
6 Grasp the thumbscrews and use them to slide the server forward. Pull the server out of the rack until it stops. The server’s cover remains in place. The enclosure and components slide forward until the interior is in view.
If you need to remove the server from the rack, press the release latches on each side of the server’s interior, then carefully slide it forward and lift it out of the cover. Press these two latches to release the server from the cover. 7 When you’ve completed your work inside the server, carefully slide it closed and tighten the front thumbscrews to secure it in the rack.
Adding Memory The server has four memory slots, at least one of which is filled at the factory. Follow these steps to add memory to the server. You can install additional dynamic random-access memory (DRAM) in packages called Dual Inline Memory Modules (DIMMs) in the four DRAM DIMM slots on the server’s main logic board. You can expand your computer’s DRAM to a maximum of 2 gigabytes (GB).
3 Open the server to its full length. See “Opening and Closing the Server” on page 52 for details. You can also remove the server from the rack (leaving the cover in place) and do the installation with the server on a sturdy flat surface. 4 Locate the RAM slots at the rear center of the server. RAM slots (4) 5 Open the ejectors on the DIMM slots you want to use by pushing down on them.
6 Align the DIMM in the slot as pictured and push the DIMM down until the ejectors snap into place. Important Do not touch the DIMM’s connectors. Handle the DIMM only by the edges. DRAM DIMM (Your DIMM’s shape and components may vary.) The DRAM DIMM is designed to fit into Connectors the slot only one way. Be sure to align the notch in the DIMM with the small rib inside the slot. With the ejectors in the open position (as shown), push down on the DIMM until it snaps into place.
Installing a PCI Card You can add to the capabilities of your server by installing cards in its expansion slots. The computer has three expansion slots, which accommodate Peripheral Component Interconnect (PCI) cards. In some models, the slot that takes a short (7-inch) PCI card can accept a 4x Accelerated Graphics Port (AGP) card. About PCI Cards for the Server Two of the server’s slots accept PCI cards up to 12 inches long; the third slot accepts a 7-inch card.
Install a PCI Card in a Long Card Slot Follow these steps to install a PCI card in one of the long PCI slots. 1 Shut down the server. Be sure to alert users of the server that it will be unavailable for a period of time. 2 Unplug the power cord from the back panel of the server. (If the cable-management arm is not attached, you will also have to disconnect cables from the back panel.) Warning The only way to disconnect power completely is to unplug the power cord.
5 Locate the long PCI slots at the back left side of the server. You can install a card in one or both slots. Cards are oriented horizontally in the server. The long PCI cards fit into an assembly unit that contains the sockets for both cards. PCI card slots (2) 6 Grasp the PCI card assembly, which may contain one or two cards, gently pull it toward the left side of the server’s enclosure, and then lift it out of the server.
7 Prepare the card slot by doing one of the following: m If a card is already in the slot you want to use, hold the assembly and remove the card, taking care not to touch its surface. Store the card in static-proof packaging made to protect it. m If no card is in the slot, be sure to remove the slot cover (which came loose when you loosened the cover’s thumbscrew on the back panel).
10 Replace the card assembly by aligning it with the connector and pressing it into place. Attach the PCI card assembly to the connector on the logic board by pushing it in sideways. Be sure to engage the card in this slot on the back panel. If the PCI card you are installing is full-length (12 inches), make sure it fits in one of these two card guides. The card guides snap forward and backward a short distance to help you position them on the cards.
Install a PCI Card in the PCI/AGP Card Slot You can install a 7-inch PCI card in the PCI/AGP card slot. Note: An AGP card requires a special adapter. Follow these steps to install a PCI card in the PCI/AGP slot. 1 Shut down the server. Be sure to alert users of the server that it will be unavailable for a period of time. 2 Unplug the power cord from the back panel of the server. (If the cable-management arm is not attached, you will also have to disconnect cables from the back panel.
5 Locate the PCI/AGP slot at the back right side of the server. PCI/AGP combo card slot 6 Prepare the card slot by doing one of the following: m If a card is already in the slot, remove it by grasping the edges and gently pulling it toward the left side of the enclosure. Store the card in static-proof packaging made to protect it. m If no card is in the slot, be sure to remove the slot cover (which came loose when you loosened the cover’s thumbscrew on the back panel).
7 Remove the card you’re installing from its packaging and hold it by its corners, taking care not to touch the gold connector or any of the components on the card. 8 Align the card’s connector with the expansion slot and carefully press it to the right until the connector is inserted all the way into the slot. Attach the PCI/AGP card to the connector by pushing it in sideways. Be sure to engage the card in this slot on the back panel.
9 Close the card retainer on the back panel and tighten its thumbscrew. Swing the small metal plate to its closed position, and tighten the thumbscrew. Warning If you removed a card from the server and did not install a replacement, be sure to place a port access cover over the empty slot in the back panel. Do not leave an empty slot without a cover. An uncovered slot can affect the air flow that cools the server’s internal components and cause damage.
3 Open the server to its full length. See “Opening and Closing the Server” on page 52 for details. You can also remove the server from the rack (leaving the cover in place) and do the installation with the server on a sturdy flat surface. 4 Locate the battery holder near the back of the server. Remove the battery by pulling it up and out of its holder. You may need to spread these two tabs slightly apart to release the battery. Spread the tabs gently so they don’t break.
