Figure 2-7. Numbering of PDUs
Each PDU has two power banks, each with a separate circuit breaker, to be used exclusively for
storage server components (Figure 2-8).

NOTE: For T800 Storage Servers, PDUs are positioned back-to-back so that they
only take up 2U of space at the bottom of the cabinet rather than the standard
4U of space. PDUs are accessible from both the front of the storage server and the
rear. Figure 2-5 illustrates PDU placement for an T800 storage server.

WARNING: To avoid possible injury, damage to storage server equipment, and
potential loss of data, do not use the surplus power outlets in the storage server
PDUs. Never use outlets in the PDUs to power components that do not belong to
the storage server or to power storage server components that reside in other
cabinets.
