Two types of XSCFU are available: the XSCFU_B for the base cabinet of the M8000 or the
M9000 and XSCFU_C for the expansion cabinet of the M9000. XSCFU_B has a connector
for cable connection to XSCFU_C provided for expansion cabinet use. XSCFU_C has no
functions for controlling the system, but it provides an interface for passing the status of each
unit in the expansion cabinet to XSCFU_B.
FIGURE B-11 and FIGURE B-12 show the XSCFU respectively.
