Dell PowerEdge 4300 Installation And Troubleshooting Manual page 143

The external drive bays at the front of a Dell PowerEdge 4300 system hold up to three
user-accessible, half-height, 5.25-inch devices (typically CD-ROM or tape drives). A
small computer system interface (SCSI) CD-ROM drive is standard in the first external
drive bay, while two additional devices of your choice can be installed in the next two
external drive bays. External SCSI devices are connected to the Ultra/Narrow SCSI
controller on the system board. A fourth drive bay accommodates a standard 3.5-inch
diskette drive, which is controlled by the diskette drive controller on the system board.
See Figure 9-1 for a general view of the various drives, connector cables, and power
cables in the external drive bays.
