Cabling for Optional SCSI Devices

C-4 Hard Drive Installation Guidelines
Depending on the model, your computer may include one of the SCSI
cables shown in the next illustration.
SCSI Cable Options
Because your computer comes preconfigured, cable configuration does
not become a consideration until you decide to add an optional SCSI
device.
Computers with 2-peripheral SCSI cables (without termination)


must have termination enabled on the last device.
C omputers with 3- and 4-peripheral SCSI cables come with a
 
terminator on the end of the cable. The connector on the

opposite end of the cable always connects to the system board.
All SCSI devices connected with these cables must have their


termination disabled.
Some devices may not have terminating jumpers on the device.
Termination on these devices must be achieved with terminated
cable.
When installing a SCSI device, be sure to route the SCSI cable over
the expansion board cage, between the raised areas.
