Before powering on the storage system, check the cord locks on the power supplies to confirm the
AC cords have become loose during shipping. Also check the AC cords and cable ties on the
PDUs to verify cord connections are secured.
Redundant Power
Before powering on the storage system, verify the system has a valid redundant power configuration.
In addition, verify each PDU connects to an independent AC input source. “Redundant Power
Configuration (T400)” (page 67) illustrates a standard, redundant power configuration and illustrates
an alternate configuration unique to some T800 storage systems.
NOTE: If a cabinet does not have components installed in the top four bays (bays 0–3) or the
highest 16U of the cabinet, the two upper PDUs (PDU 0 and PDU1) are not used to power the
system and does not need be connected. Redundant power is still supplied to the lower bays in
the cabinet through PDU 2 and PDU 3.
