Adding Internal Peripheral Devices
A CD-ROM drive, a floppy disk drive, and the primary system disk drive are installed in bays at
the front of the base unit chassis. You can add EIDE and SCSI devices to the front-access bays,
and SCSI disk drives to the internal-access bays.
A total of four front-access device bays are available in the front-access device cage. The
CD-ROM drive and the floppy disk drive occupy two of these bays. A total of three internal-
access device bays are available in the internal-access device cage. The primary system disk drive
occupies one of these bays.
The following table describes the devices in the peripheral device bays:
Location Access Device Device Size Bus
Bay 1 (top) External CD-ROM drive 5.25 in x 1.6 in EIDE (Master)
Bay 2 External EIDE/SCSI device 5.25 in x 1.6 in EIDE (Either)
Bay 3 External EIDE/SCSI device 5.25 in x 1.6 in EIDE (Either)
Bay 4 External Floppy disk drive 3.5 in x 1.0 in N/A
Bay 5 * Internal Disk drive 3.5 in x 1.0 in * SCSI
Bay 6 * Internal Disk drive 3.5 in x 1.0 in * SCSI
Bay 7 (bottom) * Internal System disk drive 3.5 in x 1.0 in * SCSI
* Two 3.5-inch x 1.6-inch devices can be installed in bays 5, 6, and 7
The EIDE controller on the system board manages internal EIDE peripheral devices. Two EIDE
devices can connect to each of the primary and secondary EIDE channels. The CD-ROM drive
connects to the primary EIDE channel as a master device. The cable for the CD-ROM drive can
connect to a second (slave) device in one of the front-access device bays. A second cable
delivered with the system is available to connect two front-access EIDE devices to the secondary
EIDE channel.
A dual-channel low-voltage differential (LVD) SCSI controller on the system board manages
internal and external SCSI peripheral devices. SCSI disk drives in the internal-access bays connect
to SCSI Channel B. The cable to the SCSI port connects to SCSI Channel A. On some systems,
the cable to the SCSI port may also connect to SCSI peripheral devices in the front-access bays
(with an optional internal/external cable).
See the following figure to locate the peripheral device bays.
