Removable Media Devices and Diskette Drives
A CD-ROM reader is always mounted in bay A. SCSI
removable media devices can be installed in periph eral
bays B and C. SCSI devices should be installed in the
first available bay from the top (bay A). Figur e 5-17
illustrates the recommended removable media
configuration. These bays are intende d to hold tape,
CD-ROM, or other removable media drive s. Narrow
SCSI drives in the 5 1/4-inch bays receiv e contro l
signals from a fast/wide SCSI-2 controller on the
system board (channel A).
Notice: The SCSI termination resistors must be
installed in the last SCSI drive of the daisy chain
cabling (top media bay A). All other devices must h ave
terminators removed.
Hard disk drives cannot be installed in a 5 1/4-inch
external bay because the drive gen erates EMI, is mo re
susceptible to ESD, and would not have sufficient
cooling.
A 1.44 MB diskette drive is always mounted in bay D.
A second 3 1/2-inch device can be installed in bay E.
