Power supply provides power to the system components. The redundant
power supply provides hot-plug capability and fault tolerance.

Power supply fans provide cooling for the redundant power supply modules.

5.25-inch drive bays provide space for as many as four 5.25-inch drives. A
CD drive comes standard with the system and occupies one of the 5.25-inch
drive bays.

N+1 power supply alarm board provides an audible alarm if a power supply
module fails.

3.25-inch drive bays support as many as two 3.25-inch drives. A diskette drive
comes standard with the system and occupies one 3.25-inch drive bay. A hard
drive is typically installed in the second drive bay.

Hot-plug bays support as many as six 1-inch high 3.25-inch SCA SCSI hard
drives. Drive bays without hard drives contain empty drive carriers to control
