2-6 Quantum DLT 7000 Tape Drive
2.2.2 Configure the Rackmount Drive for TERMPWR (Single-Ended Only)
A SCSI bus must be terminated at each end of the bus. At least one device must
supply terminator power (TERMPWR). Quantum recommends that every device
on the SCSI bus be configured to supply TERMPWR to ensure that there is a
sufficient level of voltage along the SCSI bus.
Install a jumper across Pins
3 and 4 (Figure 2-2) to enable TERMPWR.

2.2.3 Configure The Rackmount Drive for Parity Checking
The default setting for DLT 7000 tape drives is to have parity checking enabled.
If the system to which you are configuring the rackmount tape drive does not
generate SCSI parity, disable parity checking by installing a jumper across Pins 1
and 2 on the parity check connector as shown in Figure 2-2.
