Removing And Replacing The Front Bezel - Dell PowerEdge 1650 Installation And Troubleshooting Manual

The system board can accommodate one or two microprocessors. A riser board accommodates one or two PCI expansion cards. Up to four memory modules
may be installed on the system board.
The hard-drive bays provide space for up to three 1-inch SCSI hard drives or two IDE hard drives. SCSI hard drives are connected to a SCSI host adapter on
the system board through the SCSI backplane board. IDE hard drives are connected directly to the system board.
The peripheral bays provide space for an optional 3.5-inch diskette drive and a CD drive.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Two hot-pluggable, redundant power supplies provide
