Pdus; Dual Pdu Assembly - HP StorageWorks 6100 - Enterprise Virtual Array User Manual

The configuration provides complete power redundancy and eliminates all single points of failure for
both the AC and DC power distribution.
CAUTION:
Operating the array with a single PDU will result in the following conditions:
• 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
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.
