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.
