Installing SCSI Terminators

Your SCSI devices communicate with each other and with the

controller along the SCSI bus. For each SCSI bus you use

(channel A and channel B), you must mark both “ends” of the

bus with SCSI terminators. The ends of the bus are the first

device on one end of the bus (such as your SCSI interface) and

the last device on the other end (such as a SCSI hard disk

drive).

You usually install a terminator on the printed circuit board of

a SCSI device. In your computer, each of the built-in SCSI

interfaces have a built-in terminator, so you do not have to

install any to terminate the interface end of the bus. However,

you must install a terminator on the SCSI device that you

assign as the last device on the other end of the bus. You must

also remove any terminators that are installed on any devices

installed between the interface and the device on the other end

of the bus. See your SCSI device documentation for instructions

on installing and removing the terminators on your devices.

If you connect a SCSI device with a built-in terminator that

you cannot remove, that device must be the last device on

Installing SCSI Devices

The two SCSI channels in your computer each support up to

seven differential-pair or single-ended SCSI devices for a total

of 14 devices. Your system includes a SCSI device cable for one

of the channels to which you can connect up to seven SCSI

devices (including the interface). Follow the instructions in

Chapter 7 for installing SCSI devices in your computer.
