Installing Drives in the External Bays
T
he external drive bays at the front of the Dell Power-
Edge 4100 system hold up to four user-accessible, half-
height 5.25- or 3.5-inch devices, typically diskette, tape,
CD-ROM, or digital audio tape (DAT) drives. A 3.5-inch
diskette drive and small computer system interface
(SCSI) CD-ROM drive are standard in the first and sec-
ond drive bays. The diskette drive is controlled by the
system board’s built-in diskette drive controller, whereas
the CD-ROM drive is connected to the system board’s
built-in Ultra/Narrow SCSI controller. Two additional
drives of your choice can be installed in the lower two
external drive bays. See Figure 9-1 for a general view of
the various drives, control cables, and power cables in the
external drive bays.
