Power Requirements - HP 195294-001 - ProLiant - ML370R Setup And Installation Manual

The 9000 Series racks provide server cooling from flow-through perforations
ensuring 64 percent open area for ventilation. For guidelines on meeting airflow

Power Requirements

WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power
to the rack. Consult the electrical authority that has jurisdiction over your
facility's wiring and installation requirements.
CAUTION: When you need to disconnect power completely from the server, be sure
that you unplug the power cord from the power outlet.
CAUTION: Protect the server from power fluctuations and temporary interruptions
with a regulating UPS device. This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation
during a power failure.
