Terminating SCSI Devices
Read the device’s documentation to determine how to enable or disable
termination on your particular SCSI device(s). On most internal SCSI devices
the termination setting is controlled by a jumper or a switch. On other
internal SCSI devices you must physically remove or install resistor
module(s). On most external SCSI devices, a terminating plug (a resistor
pack embedded in a small plug) is installed or removed to control
termination (see Figure 7-4).
