3.2.5 Power Supply Numbering
InServ T-Class and S-Class Storage Server cabinets are divided into power domains that each
contain drive cages or controller nodes and four dedicated power supplies. These power
supplies, located at the rear of the system, receive AC power input from the PDUs, at the
bottom of the cabinet, and deliver DC power to the drive cages and controller nodes.
When viewing the cabinet from the rear, the power supplies in each power domain are
numbered from 0 to 3, from left to right. Figure 3-12 shows an expansion cabinet.
