Features
■ System board has three EISA slots, four PCI slots,
and one shared PCI\EISA slot for add-in boards.
The system board also has onboard external I/O
(serial, parallel, video) interfaces.
■ Chassis can hold 11 drives: 6 hot-swap bays for
3 1/2-inch ultra wide SCSI-2 hard drives; three
5 1/4-inch half-height bays for removable media
drives with a CD-ROM reader already installed in
one bay; and two 3 1/2-inch half-height bays with a
diskette drive already installed in one bay.
■ Chassis supports up to two power supplies. The
second power supply can be added to provide
redundant power.
Configuration Constraints
Power supplies are hot-swappable and are easily
removed and installed.
The second optional power supply provides redundant
power so that if one of the two power supplies fail, the
system will continue to operate and the failed power
supply can be hot swapped. That is the failed power
supply is removed and replaced without turning power
off.
The system has three 5 1/4-inch half-height bays
accessible from the front. These bays are convenient for
diskette, tape, and CD-ROM drives (removable media).
Because of the EMI generated by hard drives, the
increased susceptibility to ESD, and cooling
requirements, hard drives should not be installed in
the 5 1/4-inch half-height bays.
