Power in the 3592 is supplied by a redundant pair of power supplies
3
and
4
. The AC power cord
1
of
each supply is plugged into the AC power distribution unit
2
of the rack into which the 3592 is mounted.
No power ON/OFF switches are on the power supplies. Because the drive canister and the power supplies
are all single FRUs and are hot-pluggable, they do not require power ON/OFF switches to allow the
performance of service activities.
