• The standard power conﬁguration for any Enterprise Virtual Array rack is the fully redundant

conﬁguration. Implementing this c on ﬁguration 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) p er rack. Three PDMs mount vertically on each side

of the rack. Each set of PDMs conne cts to a different PDU.

• The d rive 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 o n the right with a

black, 66 cm (26 in) power cord.

• The upper controller connects to a PDM on the left with a g ray, 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 sing le 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 a t 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 c able 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 conne ctors 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.
