Configuring the new SCSI drive Termination Each device on the SCSI cable is either at an end of the chain or at a link in the middle. A SCSI device has a terminator jumper which can be set to On (for a device at the end of the chain) or Off (for devices in the middle of the chain). Generally, your computer's SCSI host adapter is at one end of the chain and a terminated device is at the other. All other devices are middle links. The SCSI host adapter can be set so you can start up from any device on the SCSI chain. SCSI IDs In addition to recognizing the ends of the SCSI chain, your computer needs to designate the order of the links. For this reason, each device on the SCSI chain requires a unique device ID. This ID can be any number between 0 and 15 (for Ultra Wide SCSI) other than 7, which is the factory preset for the host adapter. The ID number, or address, is set on most SCSI devices by adjusting jumpers on pins. www.gateway.com 15

Termination
Each device on the SCSI cable is either at an end of the chain or at a link in
the middle. A SCSI device has a terminator jumper which can be set to On (for
a device at the end of the chain) or Off (for devices in the middle of the chain).
Generally, your computer’s SCSI host adapter is at one end of the chain and a
terminated device is at the other. All other devices are middle links. The SCSI
host adapter can be set so you can start up from any device on the SCSI chain.
SCSI IDs
In addition to recognizing the ends of the SCSI chain, your computer needs
to designate the order of the links. For this reason, each device on the SCSI
chain requires a unique device ID. This ID can be any number between 0 and 15
(for Ultra Wide SCSI)
other than 7
, which is the factory preset for the host
adapter. The ID number, or
address
, is set on most SCSI devices by adjusting
jumpers on pins.
