• The standard power configuration for any Enterprise Virtual Array rack is the fully redundant
configuration. Implementing this configuration requires:
• Two separate circuit breaker-protected, 30–A site power sources with a compatible wall
receptacle (see Figure 24 ).
• One dual PDU assembly. Each PDU connects to a different wall receptacle.
• Six Power Distribution Modules (PDM) per rack. Three PDMs mount vertically on each side
of the rack. Each set of PDMs connects to a different PDU.
• The drive enclosure power supplies on the left (PS 1) connect to the PDMs on the left with a
gray, 66 cm (26 in) power cord.
• The drive enclosure power supplies on the right (PS 2) connect to the PDMs on the right with a
black, 66 cm (26 in) power cord.
• 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.
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 Figure 25 ). 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.
