2.2.3 Back up Your System
Follow your normal procedures to back up your system before installing the KZPCM Host Adapter.
2.3Terminating the SCSI Buses
The KZPCM Host Adapter has dual-SCSI channel capability, and each bus must be terminated at both ends of the bus. The Host Adapter can be located at the beginning of the bus or in the middle of the bus; consequently, termination on the Host Adapter itself can be enabled or disabled. Furthermore, if both the wide- and narrow-SCSI connectors on the A-channel are used, the narrow-SCSI termination on the Host Adapter must be disabled.
Use the termination switchpack, SW1, on the Host Adapter PCB (Figure 2-1) to enable or disable terminations on the PCB. Tables 2-1 and 2-2 show how the switchpack switches should be set according to how devices are connected to Channel A and Channel B connectors, respectively, of the Host Adapter.
