The following illustration shows the controls, LEDs, and connectors on the front of
the server. There are three different front views:
v 2.5-inch SCSI hot-swap hard disk drive
v 3.5-inch SCSI hot-swap hard disk drive
v 3.5-inch SATA non-hot-swap (simple swap) hard disk drive
Note: Both 3.5-inch configurations support an optional DVD-ROM.
