Redundant ac-power switch parts
There is a single field-replaceable unit (FRU) assembly for the redundant ac power feature. It consists of
the switch and two input-power cables.
The redundant ac-power switch is an optional feature that makes the SAN Volume Controller nodes
resilient to the failure of a single power circuit. The redundant ac-power switch is not a replacement for
an uninterruptible power supply. You must still use a uninterruptible power supply for each node.
Figure 7 shows the redundant ac-power switch.
Table 21 lists the part numbers for the redundant ac-power switch.
