8.2Accessible drives

The server accommodates three accessible drives (two 5 ¼-inch drives and one 3 ½-inch drive). As shipped, two drives are fitted: a 3 ½-inch floppy disk drive and a CD-ROM drive.

When installing or removing drives, the following points must be observed for the configuration depending on the drive type (IDE or SCSI):

IDE drive

•The drive must be entered in the BIOS Setup (see description of BIOS Setup).

•The proper master-slave setting must be set on the drive:

−If the drive is connected to an IDE channel alone, then the drive must be set as the master.

−If the drive is connected to an IDE channel together with a second drive, then one drive must be set as the master and the other as the slave.

•Only drives with the same speed should be connected to an IDE channel.

SCSI drive

•The drive must be assigned a unique SCSI-ID. With narrow SCSI drives, an SCSI-ID from 0 to 6, and with wide SCSI drives also from 8 to 15 can be assigned.

•The drive terminating resistor must be switched on or off in accordance with the following considerations:

−If the drive is connected in the middle of the SCSI cable, then the drive terminating resistor must be switched off.

−If the drive is connected at the end of the SCSI cable, then the drive terminating resistor must be switched on (also see the next point).

−If the drive is connected at the end of the SCSI cable, however the SCSI cable is equipped with its own terminating resistor, then the drive terminating resistor must be switched off.

ÊAlways read the related documentation before installing or removing a drive.
