Installing Drives in the External Bays 8-101Chapter 8Installing Drives in the External BaysThe external drive bays at the front of the computer(Figure 8-1) hold up to three user-accessible, half-height5.25- or 3.5-inch devices—typically diskette, tape,CD-ROM, or digital audio tape (DAT) drives. StandardPowerEdge 2100 systems include a diskette drive in thetop bay and a CD-ROM drive in the middle bay. A driveof your choice can be installed in the lower bay.The diskette drive is controlled by the system board’sbuilt-in diskette controller. The CD-ROM drive providedwith the system and an additional small computer systeminterface (SCSI) drive (if installed in the lower bay) arecontrolled by the system board’s built-in SCSI controller.NOTE: Dell PowerEdge 2100 systems support only SCSIhard-disk drives in the internal drive bays. For moreinformation, see Chapter 9, “Installing Drives in theInternal Bays.”Configuring a DriveBecause you may need to tailor a drive to work with yoursystem, certain installation instructions in this chapterrefer you to the documentation that came with the drivefor information on changing jumper settings.JumpersDrives installed by Dell are configured to work with yoursystem. However, you should check the documentationfor the drive to verify that the jumpers are set correctlyfor your particular configuration, and make any neces-sary alterations. (For an explanation of jumpers, see“Jumpers” in Appendix B.)For example, when daisy-chaining two drives together,you may need to reconfigure one or both drives to differ-entiate between them for proper operation.
