Removable Media Devices
A variety of IDE and SCSI removable media devices can be installed in peripheral bays A, B, and
C. An IDE CD-ROM is always mounted in bay C. A 3.5-inch diskette drive is always mounted in
bay D. Other devices should be installed in the first available bay from the top (bay A). Contact
your sales representative or dealer for a list of approved devices.

If you are adding or removing an IDE removable media device, consider the following:
n The system board supports a primary and secondary IDE channel connector. Each of these
supports two devices, for a total of four IDE devices.
n A first (master) device and a second (slave) device are supported on both the primary and
secondary IDE connector. The device configuration, master versus slave, is determined by
jumpers on the device. Cable Sense (CS) device configuration is not supported.
n
Your system includes a three-connector IDE cable connecting the CD-ROM to the system board
secondary IDE connector. The CD-ROM that comes with your system is set as the master
device. A second IDE connect is available to connect a slave IDE removable media device.
n If only one device is on an IDE channel connector it must be set as the master device.
If you are adding or removing a SCSI removable media device, consider the following:
n
The tape drive SCSI address assignment is 2.
n If the SCSI tape is your only SCSI device on the SCSI controller, SCSI termination must be
installed in the tape drive.
n
If the SCSI tape is connected along with SCSI hard drives on the SCSI controller, SCSI
termination must be removed in the tape drive.
