ProLiant Server High-Density Deployment Server Solution

Planning Rack Configurations
You must consider several important factors when planning a rack configuration:
• The number of servers deployed in the rack
• The number of other devices such as keyboard drawers, video displays, and console switchboxes
that support the servers
• The number of PDUs and their orientation
• The type of rack
• The rack management system
• The console management system
• The remote management system
• Network Interface scheme
All these factors influence floor support requirements, future service and upgrade requirements, and
installation requirements.
Weight Considerations
Due to the higher densities possible with HP ProLiant servers and HP ProLiant Infrastructure products, it
is possible to configure a rack that can present floor loading issues. Floor loading is an even more
important factor when several enclosures are positioned in one row. The Rack/Site Installation
Preparation Utility provides you with the total rack weight information necessary to verify that floor
loading remains within design specifications.
Special Considerations for Compaq Racks
HP recommends that you consider the following when installing HP ProLiant servers in Compaq racks:
• To effectively cool the HP ProLiant server in a Compaq 7000-series rack, replace the front door of
the rack with the High Air Flow Rack-Door. Install the door before deploying the servers in the rack.
• Use the Rack Extension kit (P/N 154392-B21) to alleviate any space problems for cable bundles at
the rear of Compaq 7000-series racks.
WARNING: Follow these guidelines to reduce the risk of personal
injury or damage to the equipment:
• Do not install an HP ProLiant server into a rack until the rack has
been placed in its final location.
• Preinstall slide rails, PDUs, power cords, and cables into the rack
in a build room or other location before movin
g
the rack to its final
location.
• Extend the levelin
g
jacks to the floor and rest the full wei
g
ht of the
rack on the jacks before installing any servers. The casters are not
designed to support the full weight of a populated rack.
• Do not move a rack populated with servers. A fully populated rack
can weigh up to 771 kg (1,700 lb). Moving a populated rack can
cause the rack to become unstable, resulting in serious personal
injury or equipment damage.
