Terminator Power 2
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 occurs, terminator power
to the bus is interrupted. After the short is removed, a fuse in
the drive is automatically reset, restoring terminator power.
