CMF External Connectivity
Table 5–1 lists the corresponding package styles required for connection of an external
CS-bus to an external channel rack (RM5-CA4 or RM5-CA5) and includes the appropriate
Feedthru board (3U or 6U Feedthru depending on the style below). Order one package
style for each CMF to be connected to external channel rack(s). When migrating channels
from older systems, order appropriated CSB3-E3U or CSB3-E6U kits to provide CSBus 3
type cables and interface cards.
