Configuring the Boot Device

Your system contains up to five 1-inch SCSI hard drives. A CD drive and a diskette drive are mounted together on a tray that

slides in the front panel and SCSI backplane board. This design allows the diskette and CD drives to be serviced without

removing the cover or connecting and disconnecting cables. This section contains instructions for replacing these devices.

SCSI Interface Cables

SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in

the connectors on both ends. When you disconnect an interface cable, take care to grasp the cable connector, rather than the

cable itself, to avoid stress on the cable.

SCSI Configuration Information

Although SCSI devices are installed in essentially the same way as other devices, their configuration requirements are

different. To configure an external SCSI device, follow the guidelines in the following subsections.

SCSI ID Numbers

Each device attached to a SCSI host adapter must have a unique SCSI ID number from 0 to 15.

A SCSI tape drive is configured by default as SCSI ID 6.

NOTE:

There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the

cable in order by ID number.

Device Termination

SCSI logic requires that termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all

devices in between. For internal SCSI devices, termination is configured automatically. For external SCSI devices, you should

disable termination on all devices and use terminated cables. See the documentation provided with any optional SCSI device

you purchase for information on disabling termination.
