Quarter-Inch Cartridge (Qic) Tape Drive Configuration - HP 3000 Series Handbook

For HP Internal Use Only
Quarter-inch Cartridge (QIC) Tape Drive Configuration
Caution
'
The drive configuration is set for the system it is installed in. Changing the
configuration may cause the drive to malfunction.
Devices installed outside the system will be configured differently.
The location of the jumpers and termination resistors on the Drive Controller PCA is
shown in Figure 4-15. The location of the jumpers on the lv1otor Driver PCA is shown in
Figure 4-16.
See Table 4-22 andFigure 4-15 . JP1 determines the SCSI address of the QIC drive. In this
system, the internal tape drive is always set to address zero. No jumpers are installed.
JP2 pin 1 determines the type of SCSI interface. A jumper is always installed on pin 1 to
select the SCSI-2 interface.
JP2 pin 2 through 9 are never jumpered.
The termination resistors are located at RN1, RN2, and RN3. All termination resistors must
be removed before the tape unit is installed.
See Figure 4-16. JPl is always jumpered. The jumper provides a logic ground to chassis
ground connection.
