hot-pluggable redundant power supplies that are front loadable and slide into connectors mounted on the the PDB. When this option is installed, the PDB will provide
power to the system board, SCSI backplane board, and internal peripherals.
For non-SCSI drives such as the diskette drive and CD-ROM drive, an interface cable connects the interposer board, attached to the diskette drive and CD-ROM
drive, to the system board. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter
either on the system board or on an expansion card. (For more information, see "Installing Drives").
