Base-520(G) Installation
SCSI #1 Configuration
SPARC/CPCI-52x(G)
Page 39
Default
configuration 1
for 8 bit SCSI
•
The default configuration 1 is covered by the default switch setting:
The Base-520(G) is located at an endpoint of the SCSI #1 bus, the
SCSI #1 bus is extended via the CompactPCI backplane (J5 connec-
tor), but no SCSI cable is plugged into the front-panel SCSI connec-
tor:
In this configuration (default switch setting):
– SW5-1 must be set to OFF = front panel termination automatic
(automatic enabling or disabling of termination by sensing whether
a SCSI cable is plugged in)
– and SW5-2 must be set to OFF = backplane termination disabled.
Default
configuration 2
for 8 bit SCSI
•
The default configuration 2 is also covered by the default switch set-
ting: the Base-520(G) is not located at an endpoint of the SCSI #1
bus, the SCSI 1 bus is extended via the CompactPCI backplane and
via the front-panel SCSI connector:
In this configuration (default switch setting):
– SW5-1 must be set to OFF = front panel termination automatic
(automatic enabling or disabling of termination by sensing whether
a SCSI cable is plugged in)
– and SW5-2 must be set to OFF = backplane termination disabled.
