Rack planning resources
The rack resource kit ships with all HP-branded or Compaq-branded 9000, 10000, and H9 Series
racks. For more information on the content of each resource, see the rack resource kit documentation.
If you intend to deploy and configure multiple servers in a single rack, see the white paper on
high-density deployment at the HP website: http://www.hp.com/products/servers/platforms.
Rack warnings
WARNING!
To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one com-
ponent is extended for any reason.
WARNING!
To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can
weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become unstable
when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle
the rack from both sides.
Environmental requirements
When installing the enclosure in a rack, select a location that meets the environmental standards
described in this section.
