Installing Drives in the External Bays

The 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.
