Upgrading Your System 4-31
Removable Media Devices
A CD-ROM drive is always mounted in bay D. Any SCSI removable media devices can
be installed in peripheral bays A, B, and C. The SCSI devices should be installed in the
first available bay from the bottom (bay D).
Figure 4-18 illustrates the recommended removable media configuration. The bays are
intended to hold tape, CD-ROM, or other removable media drives. Narrow SCSI drives
in the 5 1/4-inch bays receive control signals from channel B of the SCSI-2 controller
on the system I/O board.
Note:
The SCSI termination resistors must be installed in the
last SCSI drive of the daisy chain cabling (bottom media bay D). All
other devices must have terminators removed.
Hard disk drives cannot be installed in a 5 1/4-inch external bay because the drive
generates EMI, is more susceptible to ESD, and does not have sufficient cooling.
A 1.44 MB diskette drive is always mounted in bay E. A second 3 1/2-inch device can
be installed in bay F.
