Configuring Channel Racks
Channel racks expand IOM connectivity beyond the channel slots provided in the system
cabinet. Two styles of channel rack are available:
RM5-CA4 - With fascia for open-door style cabinets
RM5-CA5 - Without fascia, for louvered-door style cabinets
Each channel rack connection requires:
CSB3-E3U CSBUS3 External CMF W/3U Feedthru
or
CSB3-E6U CSBUS3 External CMF W/6U Feedthru
WARNING
When connecting external channel racks to a CS-bus III interface, check
to ensure that only CS-bus III style components are used, that is,
CSB3-3U or CSB3-6U feedthrough card and CSB3-XXC cable. Mixing
CS-bus II and CS-bus III interface component styles on external channel
rack interfaces will result in damage to the equipment.
Table 43 describes channel rack components. Table 44 provides configuration
guidelines. Table 45 provides guidelines for configuring the power net in channel racks.
For guidelines on configuring the channels themselves and when to use external channel
racks, refer to "Configuring Channels" in Section 5.
