Rack Warnings And Caution - HP Apollo 4200 Gen9 User Manual

WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power
cord to remove power from the server. The front panel Power On/Standby button does not completely
shut off system power. Portions of the power supply and some internal circuitry remain active until AC
power is removed.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply. This device protects the hardware from damage caused by power surges and voltage
spikes and keeps the system in operation during a power failure.

Rack warnings and caution

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.
