Pdus - HP 6100 User Manual

The upper controller connects to a PDM on the left with a gray, 152 cm (60 in) power
◦
cord.
The lower controller connects to a PDM on the right with a black, 66 cm (26 in) power
◦
cord.
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 Command View EVA 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 228481-002/228481-003 PDU placement is back-to-back, plugs facing down,
with switches on top.
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.
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 (see
60)). The voltages are then routed to PDMs, sometimes referred to as AC power strips, mounted
on the two vertical rails in the rear of the rack.
