Pedestal Configuration Rules
This chapter describes configuration rules for bus configurations, device addresses, power, SBBs, and the
SCSI buses. It also describes how to reconfigure the pedestal from one to two SCSI buses.
NOTE
In addition to the configurations described below, two
pedestals may be configured on one SCSI bus with the
purchase of additional equipment. Refer to

3.1
Bus Configurations
The pedestal is configured at the factory for a single SCSI bus. It may be reconfigured
for two SCSI buses if desired (Section 3.5.2). The following rules apply:
•
Eight and 16-bit devices can be mixed in the first pedestal when it’s configured for
either one or two SCSI buses. A maximum of 7 devices can be installed with no
redundant power supply or battery backup unit. (See Section 3.2.1.)
•
A personality module, located above slot 0 in the pedestal, automatically terminates
the SCSI bus in all configurations except when two SCSI buses are configured in one
pedestal.
NOTE
The optional terminator block must be ordered separately If
it’s required for your configuration as explained below.
•
An optional terminator block is required for configuring two SCSI buses in one
pedestal. If you are configuring two SCSI buses in one pedestal, refer to Section
3.5.2.
