Figure 26 60-Hz and 50-Hz wall receptacles
NEMA L6-30R receptacle, 3-wire, 30-A, 60-Hz
IEC 309 receptacle, 3-wire, 30-A, 50-Hz
• 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 26 (page 53)).
◦ 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.
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 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
