Pdus - HP 6400/8400 User Manual

NOTE: Drive enclosures, when purchased separately, include one 50 cm black cable and one
50 cm gray cable.
The configuration provides complete power redundancy and eliminates all single points of failure
for both the AC and DC power distribution.
CAUTION:
No redundancy
Louder controllers and disk enclosures due to increased fan speed
HP P6000 Command View will continuously display a warning condition, making issue
monitoring a labor-intensive task
Although the array is capable of doing so, HP strongly recommends that an array operating with
a single PDU should not:
Be put into production
Remain in this state for more than 24 hours

PDUs

Each Enterprise Virtual Array rack has either a 50- or 60-Hz, dual PDU mounted at the bottom rear
of the rack. The PDU placement is back-to-back, plugs facing toward the front
21)), with circuit breaker switches facing the back
The standard 50-Hz PDU cable has an IEC 309, 3-wire, 30-A, 50-Hz connector.
The standard 60-Hz PDU cable has a NEMA L6-30P, 3-wire, 30-A, 60-Hz connector.
If these connectors are not compatible with the site power distribution, you must replace the PDU
power cord cable connector. One option is the NEMA L5-30R receptacle, 3-wire, 30-A, 60-Hz
connector.
Each of the two PDU power cables has an AC power source specific connector. The circuit
breaker-controlled PDU outputs are routed to a group of four AC receptacles. The voltages are
then routed to PDMs, sometimes called AC power strips, mounted on the two vertical rails in the
rear of the rack.
