HP ProLiant DL380 Generation 4 Server Reference and Troubleshooting Guide
Because of the high ground-leakage currents associated with multiple servers
connected to the same power source, HP recommends the use of a power
distribution unit (PDU) that is either permanently wired to the building's branch
circuit or includes a nondetachable cord that is wired to an industrial-style plug.
NEMA locking-style plugs or those complying with IEC 60309 are considered
suitable for this purpose. Using common power outlet strips for the server is not
recommended.
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 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.
