Configuration Modules CAUTION:
Configuration modules must be installed or replaced by qualified
service personnel only.
The CR8e’s SCSI bus design provides either of two bus configurations which is
determined by the configuration module installed. The Dual-Bus module provides
a split bus configuration where the enclosure’s top four drive slots and the lower
four drive slots are on two independent SCSI buses. The Single-Bus module
connects both SCSI buses together tying all drive slots to one SCSI bus.
The Single-Bus module is larger in physical size than the Dual-Bus module and is
easily identified by its description silkscreened on the module card. It is installed
on the backplane printed circuit board, at location JP1, and is accessed from the
rear door panel.
The connector is keyed and the module will only install in one direction. For
illustration purposes, the tower system is used to depict the location of the
modules.
