  • Page 25: General Computer Room Requirements

    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.
  • Page 26 • Ensure that all equipment and flooring are properly grounded and are at the same ground potential. • Use conductive tables and chairs. • Store spare electric parts in antistatic containers. • Maintain recommended humidity level and airflow rates. HP StorageWorks XP12000 Disk Array Site Preparation Guide...

  • Page 27: Safety Requirements

    Equipment servicing hazards Your staff and HP service personnel require safe access to the disk array. Running electrical and data communication cables underneath your computer room’s raised floor is the best way to ensure that they do not create a safety hazard.

  • Page 28: Raised Floor Requirements

    The maximum point floor loading is 500 kg (1102.3 lb). To estimate the load rating you need for your floor, consider the total weight of all of these items: • The disk array; see “Weights” (page 19) • Other equipment HP StorageWorks XP12000 Disk Array Site Preparation Guide...

  • Page 29: Floor Covering

    HP recommends the use of a tiled raised floor. Caution HP strongly discourages the use of carpeting, including antistatic varieties, within 6.0 m (20 ft.) of the disk array. Over time, carpeting may shed dust that can cause problems with the disk array.

    Voltages outside of the operating range of the disk array can cause intermittent system errors or a complete system shutdown. If required, an HP representative and your electrician can determine the current line voltage and make recommendations.

  • Page 54: Frequency

    Usually, AC line frequency is determined by your local power providers. In some cases, electrical power is supplied by motor-generators. Shifts in AC line frequency can cause system errors. An HP representative can monitor the frequency of the input AC line power and make recommendations, if necessary.

  • Page 55: Receptacles

    The disk array requires a solidly conductor-connected ground and may require a separate neutral in the case of WYE or STAR connections. For HP disk arrays, TN grounding systems are preferred. Receptacles Each disk array cabinet has two or four separate connections to AC power.

  • Page 56: Power Line Transients

    The additional ground can be hard conduit. Specific power plugs and receptacles are required for the DKC and DKUs depending on the power option you specify when ordering the HP XP12000 disk array. The power cords on 60 Hz cabinets are shipped with plugs attached and connected.
