The three redundant power supplies are installed vertically in a row at the front of the chassis. They can be installed and lifted out of the unit using a handle that rotates upward. (To release the handle, press on it until it pops up; to secure it, press it down until it clicks into place.) When fully installed, a power supply automatically mates with a connector on the PSPB, which lies under the power supplies. The PSPB controls the power supplies and supplies them with AC power via the AC routing cable.

Two indicators on the top of each power supply (see Figure 1-9) signal the status of the power supply. Both indicators light briefly during initial system start-up; the green status indicator stays on to show that the power supply is operating normally. The red fault indicator turns off after initial system start-up is complete. If it lights any time after system start-up, a fault is indicated in the power supply and the power supply should be replaced.

The power supplies can operate from an AC power source of 90 to 265 VAC at 47 to 63 Hz. They provide the DC operating voltages and currents listed in Table 1-2.

NOTE: The power supplies produce DC voltages only under their loaded condition. Therefore, when you measure these voltages, the power supplies must be mated to the PSPB, and the DC power cable harnesses must be connected to the PSPB and to their corresponding system loads (the system board, SCSI backplane board, and so forth).
