SCSI ID settings
Jumper Pins:
1-2, 3-4, 5-6, 7-8
Default Settings:
SCSI ID 6
Each SCSI device on the bus must have its own unique ID. Your internal tape
drive is shipped with a default SCSI ID of 6. If another SCSI device in the SCSI
chain is already using this ID, use jumper pins 1–2, 3–4, 5–6, and 7–8 to change the
drive’s SCSI ID.
Note:
If you change the drive’s default SCSI ID, avoid using SCSI IDs 0 and 1
(which typically are assigned to a boot drive) and SCSI ID 7 (which typically is
assigned to SCSI controllers or host bus adapters).
Parity checking
Jumper Pins 9-10:
Pins 9-10 shunted: Enable parity checking
(default)
Pins 9-10 open: Disable parity checking
By default, parity checking is enabled on the internal tape drive. To disable parity
checking, remove the jumper from pins 9 and 10.
Note:
If you disable parity checking, the drive still generates a parity bit.
Terminating power
Jumper Pins 11-12:
Pins 11-12 shunted: Enable terminator
power
Pins 11-12 open: Disable terminator power
(default)
By default, terminator power is disabled on the internal tape drive. To enable
terminator power, place a jumper across pins 11 and 12.
Note:
If you enable terminator power, be careful not to short the TERMPWR signal
to ground (for example, by attaching the SCSI cable upside down). If a short
