CAUTION:
For proper cooling, do not operate the server without the access panel, baffles, expansion slot
covers, or blanks installed. If the server supports hot-plug components, minimize the amount of time
the access panel is open.

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
component 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 might 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.
WARNING:
To reduce the risk of personal injury or damage to the equipment, adequately stabilize the rack
before extending a component outside the rack. Extend only one component at a time. A rack may
become unstable if more than one component is extended.
WARNING:
When installing a server in a telco rack, be sure that the rack frame is adequately secured at the top
and bottom to the building structure.
