The system unit is designed to accommodate up to four 1.6-inch or six 1.0-
inch hot swappable drives, one combination 3.5-inch floppy and IDE CD-
ROM, and one 5.25-inch half height removable media bay. The combination
CD-ROM and diskette drive connect to the SAF-TE transition module
attached on the system just to the rear of the combination unit. For more
information about the storage subsystem, refer to Chapter 7, "Using the
Storage Subsystems".
Whenever you install another SCSI device in the removable media bay area,
you must assign it a unique SCSI ID number. Otherwise, the system will not
recognize the device. Use the SCSI cable for connecting the drive to the SCSI
controller.
To install a drive in the spare bay, complete the following procedure.
1. Install the drive into the drive holder and secure it with four screws (two
on each side).
2. Install the drive holder into the system and secure it with four screws
(two on the top and two on the bottom).
3. Plug in one end of the SCSI cable to the SymBIOS adapter 895 card
located in PCI slot 2 (the cable must be 3 Meters).
4. Plug in the other end of the SCSI cable to the SCSI connection on the
rear of the storage backplane.
