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 4–3 describes channel rack components. Table 4–4 provides configuration
guidelines. Table 4–5 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.
