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.
