1.2 EF- and RZ-Series ISE Installation Preparation
EF- and RZ-series ISEs require that bus node ID jumpers be set on the drive
before the ISE can be installed in a BA400-series enclosure.
When installing an EF- or RZ-series ISE, refer to the reference booklet or data
sheet that is shipped with the ISE to set the proper bus node ID (DSSI/SCSI
ID) jumpers. Also ensure that the TERM PWR and the TERM ENABLE
jumpers are removed. Failure to remove the TERM ENABLE jumper will
cause improper operation of the ISE.
Note
Some of the ISEs have two sets of jumpers for setting the bus node ID.
Refer to the reference booklet or data sheet that is shipped with the
ISE to set the proper bus node ID on one set of jumpers only. Ensure
that all of the jumpers are removed from the second set of device
address (Node ID) jumper pins.
In VAX 4000 systems, the SCSI termination and TERM PWR are provided by
the controller module on one end of the bus and termination for the other end
of the bus is provided by an external terminator.
Note
Refer to Section 1.4.4 for bus node ID configuration guidelines.
