2 Site requirements Your site must meet the following requirements before HP can deliver and install the system.
HP SVS200 physical specifications This section describes the physical equipment and provides the specifications you need in order to determine the total dimensions and weight of your configuration.
Basic configuration The basic system consists of one 19-inch rack containing: • One controller with control panel and SVP blade PC • Mix board with host ports • Power supplies, power distribution units (PDUs), backup batteries, and power cords Expansion You can expand the rack as follows: • Add a second factory-installed controller above the first controller • Add other equipment above the controller Dimensions Use the packaged and unpackaged values below when determining delivery and transport space requi
Weight and other parameters The following tables list components of the HP SVS200 and provide approximate values (rounded up) for weight, heat output, power requirements, and air flow requirements. We recommend you use the totals shown for a fully optioned system so you will not have to modify your site if you add options later. The second table shows the maximums if you add a second HP SVS200 Controller with all options in the same rack.
Delivery space requirements The delivery area must provide enough space and floor strength to support the packaged equipment cartons for the system. Refer to Dimensions and weights and Component weights for details. CAUTION: Make sure that your doorways and hallways provide enough clearance to move the equipment safely from the delivery area to the computer room. Permanent obstructions such as pillars or narrow doorways can cause equipment damage. If necessary, plan for the removal of walls or doors.
General computer room requirements The goal of a computer room is to maintain an ideal environment for computer equipment, including this system. Make sure your computer room adheres to all national and local building codes for a data center/computer room environment. HP recommends that you follow these general guidelines: • Locate the computer room away from exterior walls of the building to avoid the heat gain from windows and exterior wall surfaces.
Safety requirements When making decisions concerning site safety, your first concern should be the safety of your personnel and then the safety of your equipment. Fundamental safeguards for systems should include a site well away from any sources of potential damage. If you have any questions on site safety, consult your HP representative, your insurance carrier, and local building inspectors for safety recommendations.
Space planning requirements Space planning involves making sure that your computer room: • Is large enough to hold the new system and other equipment and furniture • Provides clearance around the system for service access and to ensure proper weight distribution on the computer room’s floor • Includes correctly positioned floor cutouts for the system’s power and data cables The space planning process 1. Document your computer room’s existing floor plan, including locations of these items: a.
Estimating required floor load rating To estimate the load rating you need for your floor, consider the total weight of all of these items: • • • • • The system; see the preceding Component weights Other equipment Furniture such as desks, chairs, and storage cabinets Computer room personnel Moving equipment such as forklifts, dollies, and similar items The lower the floor load rating, the more clearance is required around the system to distribute the equipment weight correctly.
Floor clearance and cutout dimensions Figures on the following pages show the clearance dimensions, locations of floor cutouts, and other dimensions for the SVS200 rack. NOTE: The HP SVS200 includes a cabling hole with sliding cover in the top of the rack for cable drops from the ceiling. The hole is located in the left rear corner of the rack. This gives you the option of feeding cables to the rack from the ceiling or from the floor through a floor cutout (described below).
Calculating clearances The total floor clearance required for the system includes: • The actual space required by the equipment. • Service clearance — the floor space required to access the system. Never use this space for storage. • Additional space required to properly distribute the equipment weight on your computer room’s raised floor. The amount of additional space required depends on your floor load rating.
Calculate rack clearance dimensions as follows: • Clearance “a” is the space between the service clearance at the left side of the system (100 mm minimum for installing the kickplate) and any other object, such as a desk or wall. • Clearance “b” is the space between the service clearance at the right side of the system (100 mm for the kickplate) and any other object. • Clearance “c” is the space between the service clearance at the front of the system and any other object.
Rack clearance notes and floor loading The following notes apply to the preceding rack dimensional figures. Note *1: Clearance (a+b) depends on the floor load rating and clearance “c”. Required clearances for various floor load ratings are shown below. Floorload rating (kg/ m2) Required clearance (a + b) mm Clearance (c) mm c = 0 c = 200 c = 400 c = 600 c = 1000 500 100 0.00 0.00 0.00 0.00 450 200 100 100 0.00 0.00 400 300 200 200 100 0.
Environmental requirements The environmental specifications for operating this system must be satisfied before installation. Altitude The maximum altitude for system operation is 3,000 meters. For nonoperational or storage situations, the maximum altitude is 4,000 meters. Air conditioning Use separate computer room air conditioning duct work. If it is not separate from the rest of the building, it might be difficult to control cooling and air pressure levels.
Humidity specifications Maintain proper humidity levels. High humidity levels cause galvanic actions to occur between some dissimilar metals. This eventually causes a high resistance between connections, leading to equipment failure. 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.
Mechanical vibration specifications Continuous vibration can cause a slow degradation of mechanical parts and, when severe, can cause data errors in disk drives. Mechanical connections such as printed circuit assembly (PCA) conductors, cable connectors, and processor backplane wiring can also be affected by vibrations. Vibration specifications apply to all three axes. For vibration testing methods, see ASTM D999-91 Standard Methods for Vibration Testing of Shipping Containers.
Acoustics The acoustic emission specification for the system is: • 65 dB (A) sound pressure, operator position (1 meter from the floor and surface of the cabinet) You can reduce the ambient noise level caused by equipment and air conditioning blowers in your computer room by: • Installing a dropped ceiling covered in commercial-grade, fire-resistant, acoustic-rated, fiberglass ceiling tile • Covering the walls in sound-deadening material • Installing foam rubber removable partitions Dust and pollution cont
Data comm requirements Route data comm cables away from areas of high static electrical fields created by power transformers and heavy foot traffic. Use shielded data comm cables that meet approved industry standards to reduce the effects of external fields. For the HP system, you need: Item Description A dedicated analog phone line Needed for the HP StorageWorks Continuous Track XP “phone home” feature, if you plan to use it. An HP representative will configure Continuous Track XP.
Electrical requirements The following text explains the electrical requirements of your site to support the HP system. Line voltage Line voltage (AC) at the wall power outlet is a function of the local power utility and your building power distribution network. Voltages outside of the operating range of the HP system can cause intermittent system errors or a complete system shutdown. If required, your electrician can determine the current line voltage.
AC connections The system rack has four separate connections to 200 VAC, single-phase, 20-amp power. When receptacles are used to connect system components to AC power, they must include a dedicated ground connection that is insulated from the receptacle. It is important that the receptacle box be grounded with an additional ground connection that is separate from the dedicated ground. The additional ground can be hard conduit.
Uninterruptible power supply (UPS) The HP SVS200 system does not require a UPS; however, most systems are installed in data centers where a UPS strategy is already in place for storage devices. You should use the same UPS strategy for the HP SVS200 that you use for the storage it controls. CAUTION: To prevent UPS overload and loss of data, make sure your UPS satisfies the requirements for power listed under Component weights and also under AC line voltage requirements.
Site requirements
3 Electrical specifications The detailed electrical specifications in this chapter are provided to help your site electrician perform any necessary electrical work related to site prep. AC line voltage requirements The SVS200 operates on 200 VAC nominal, 20 amps, 50 or 60 Hz, single-phase power. Two power cords connected to the lower two power distribution units in the rack are required to power a single HP SVS200 Controller.
AC inputs The system has two separate connections to 200 VAC, single-phase, 20-amp power for one HP SVS200 Controller or four connections for two HP SVS200 Controllers. Each AC input must have its own circuit breaker and must be capable of supporting the entire current demand for a Controller. The AC power inputs to the rack connect to four power distribution units (PDUs) as shown in the following figure.
HP offers the following AC power cables and connectors, which you can order individually: • • • • • • • • • HP HP HP HP HP HP HP HP HP 4.5 m power cord w/NEMA L6-30P plug 4.5M power cord w/Nema L6-20P plug 4.5 m power cord with stripped ends 240 V power cord w/ IEC 309 plug, 4.5 m 240 V power cord w/ CEE7/7, 4.5 m Power cord for China Power cord for Israel Power cord, 4.5 m, C19/C20 Plug (jumper for UPS) Power cord w/IEC 320-C20 connector and 2.
North American AC power cabling The HP SVS200 rack requires 20-amp, single-phase 200 VAC power supplied by four power cords with plugs, four receptacles, and four main disconnect devices (circuit breakers). The HP SVS200 comes from the HP factory with the AC power cords and plugs you have ordered. Plug types rated for 30 Amps and 20 Amps are specified under the heading, AC inputs earlier in this chapter.
European AC power cabling The HP SVS200 rack requires 20-amp, single-phase 200 VAC power supplied by four power cords with plugs, four receptacles, and four main disconnect devices (circuit breakers). The HP SVS200 comes from the HP factory with the AC power cables and plugs or stripped ends you have ordered. Plug types are specified under the heading, AC inputs. The opposite end of the power cord connects to the HP SVS200 power distribution unit (PDU) input, which is a type IEC 320-C20 connector.
Connecting the European power-supply cables Connect each AC power cable to a separate receptacle on a separate circuit breaker, and connect each pair of power cords (the left pair and the right pair) to separate distribution panels to ensure power fault tolerance. Single-phase power cable wiring is shown in the figure below. CAUTION: Do not apply power until instructed to do so by HP. An HP representative should be present whenever the system is being connected to a new power source.
4 Delivery and unpacking The system equipment is shipped directly from HP. If the system is part of a system order, HP coordinates shipment from all HP locations so that all of the equipment arrives at your site at approximately the same time. When your equipment ships, HP provides you with carrier information and an expected delivery date. Factors beyond HP’s control can cause delivery delays.
Checking for shipping shortage and damage Upon delivery of each equipment shipment: 1. Check the carrier’s bill of lading to ensure that the items listed match the items delivered. Notify the carrier immediately if there are any discrepancies or missing items. 2. Inspect all shipping containers for signs of damage, such as dents, scratches, cuts, or water marks. 3. If you see any damage to the containers: a. Note on the bill of lading that there is apparent damage, subject to inspection. b.
Packaging configurations The HP SVS200 rack ships in one of three standard packaging configurations: • Environmental pack — consists of stretch wrap over corner protectors. No special tools or procedures are required to unpack shipments in this form. This packaging is used for most shipments within the USA that are direct from the factory to the customer. HP uses special carriers with a dedicated fleet of trucks and specially trained personnel.
Safety precautions CAUTION: Be very careful when handling the equipment. Do not drop the equipment from a height of more than 0.5 cm (0.2 in). Floor unevenness must be less than 1 cm (0.4 in). WARNING! The equipment frame is very heavy. To avoid injury, use appropriate lifting tools and have three people unpack and move the equipment. CAUTION: Any movement of the equipment by forklift should be done prior to unpacking. The carton assembly provides the most secure support of the equipment during movement.
Removing packaging materials 1. If shipped in a wooden crate: a. Using an 11mm (7/16") ratchet or wrench, remove the six lag screws at the base of the crate. b. Using the claw end of a claw hammer, remove the crate clamps, and then remove the crate panels. WARNING! Crate clamps are under tension. Wear safety glasses and hold onto the clamp with your free hand during removal.
2. Cut and remove the polyester bands (1). 3. Remove the nails attaching the carton to the pallet (2). 4. Remove the plastic carton fasteners (3). 5. Remove the carton. 6.
