Figure 18 Rear View of the Power Domains Within the Controller Nodes and Drive Chassis
WARNING! To avoid possible injury, damage to storage system equipment, and potential loss
of data, do not use the surplus power outlets in the storage system PDUs. Never use outlets in the
PDUs to power components that do not belong to the storage system or to power storage system
components that reside in other cabinets.
To support redundant power:
• The power supplies in each power domain must connect to separate PDUs.
• Each PDU in the system must connect to an independent AC circuit.
Figure 19 (page 35) and Table 15 (page 35) contain information about power cord connections
for S800 and T800 storage systems with PDUs placed back-to-back to take up only 2U of cabinet
space rather than the standard 4U of space.
NOTE: “ Redundant Power Configuration Diagram (S800 and T800)” (page 35) applies only
to the S800 and T800 configurations with front and rear PDUs.
