The PSPB receives input from the AC power source and distributes it to the power supplies. The power supplies return DC power to the PSPB, which in turn distributes redundant DC power to the system board, SCSI backplane, fan assembly, and external drive bays. Through embedded server management (ESM), the PSPB can also be used to perform such tasks as detecting the presence of one to three power supplies; monitoring voltage and current outputs from the power supplies, voltage going to the system board, and fan RPMs; and supporting the SMB_ALERT protocol used by the server manage- ment bus (SMB).
The PSPB sits under the power supplies, which automatically mate to connec- tors on the PSPB when they are installed. For information on removing and replacing the PSPB, see
