Preparation Procedures; Remove The Security Bezel (Optional) - HP ProLiant DL160 Gen9 Maintenance And Service Manual

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.

Preparation procedures

To access some components and perform certain service procedures, you must perform one or more of
the following procedures:
