    Overview As computer systems have evolved in size and complexity, managing them has become a critical concern. By centralizing your equipment in a HP 10000 Series rack, the efficiency and accessibility of your system can be increased dramatically. The 10000 Series racks are designed to house rack-mountable products on industry- standard 19-inch (48.26-cm) wide rails.

  • Page 12

    Overview • Interchangeable front and rear doors that allow the rack to be used in server/storage or switching applications NOTE: Customers wanting to utilize the 10842 rack exclusively for switching devices, such as routers and switches, have two options: • Interchange the front and rear doors to make use of the mounting rail front justification, allowing room in the front of the rack for cabling.

  • Page 13: Rack Options

    Overview Rack Options In addition to the standard rack, HP also provides rack options to complement or to complete your rack solution. The following list is only a sampling of the many rack option kits available. For more information, refer to the HP website, www.hp.com Table 1-1: Rack Options Option...

  • Page 15: Delivery Considerations, Installation Sequence Summary

    Overview Delivery Considerations The following list is only a sampling of the many delivery considerations available. For more information, visit the Best Practices Web page at www.hp.com. When preparing to receive palletized racks, consider the following: • The dock door at the receiving site has to accommodate the height and width of palletized racks.

  • Page 16: Installation Service

    Overview 8. Install products such as Uninterruptible Power System (UPS) units starting from the bottom of the rack. 9. Install the appropriate support rails and/or tray for the first rack-mountable component. 10. Install the first individual component. 11. Attach a cable management arm, if required. 12.

  • Page 17: Rack Configuration Software, Rack Builder Online Modes Of Operation

    Configuration Factors Before populating your new rack, it is important to plan the placement of each component. Factors of each component, such as weight, accessibility, power, temperature, and airflow requirements, affect installation order and component placement in the rack. Rack Configuration Software To help you plan your rack configuration more efficiently, HP provides Rack Builder Online, the browser-based rack configuration tool.

  • Page 18: Rack Builder Online Features

    Configuration Factors Rack Builder Online Features The Rack Builder Online software offers the following features. • Multiple-Rack Configuration—Allows up to six racks to be viewed and configured onscreen in one session • Graphics—Uses graphical representations of the systems to illustrate the U height that each component occupies •...

  • Page 19: Rules For Component Placement, Additional Considerations

    Configuration Factors Rules for Component Placement The following rules apply to the physical placement of components in the rack. • Weight—Sort all components by weight, placing the heaviest components at the bottom of the rack. • Balance—Be sure to balance the weight load between racks, placing the heaviest components at the bottom.

  • Page 20

    Configuration Factors • Monitor—The monitor requires installation of a Monitor/Utility Shelf Rack Option Kit unless you are using a rack-mountable flat panel monitor. • Server Console Switch—If a switch box is configured, use the CPU-to-Switch cable included with the server. The standard distance between the switch box and the keyboard, monitor, and/or mouse can vary by 3-, 7-, 12-, 20- and 40-foot (91.44-, 213.36-, 365.76-, 609.6-, and 1219.2-cm) lengths.

  • Page 21: Optimum Environment, Space Requirements, Power Requirements

    Configuration Factors Optimum Environment Specific requirements for space, power, temperature, and airflow must be met to provide optimum performance with minimum maintenance for your rack environment. Space Requirements When deciding where to place your rack: • At least 122 cm (48 inches) of clearance is needed all the way around the pallet and above the rack to allow the removal of packing materials.

  • Page 22: Grounding Requirements

    Configuration Factors CAUTION: To reduce the risk of damage to the equipment, verify that all AC voltage selector switches are set correctly to match your local AC line voltage (115V or 230V). If the AC voltage selector switch is not properly set, your components will be damaged when power is applied.

  • Page 23: Temperature Requirements

    Configuration Factors Temperature Requirements For safe and reliable operation of equipment, locate the system in a well-ventilated, climate-controlled environment. The HP Maximum Recommended Ambient Operating Temperature (T ) for most server products is 95°F (35°C). Therefore, the temperature in the room where the rack is located should not exceed 95°F (35°C).

  • Page 24: Airflow Requirements

    Configuration Factors Airflow Requirements HP rack-mountable products typically draw in cool air through the front and exhaust warm air out through the rear of the rack. The front door of the rack, therefore, must be adequately ventilated to allow ambient room air to enter the rack, and the rear door must be adequately ventilated to allow the warm air to escape the rack.
