Switch Fabric Module (SFM and SFM2) Connectors and LEDs

The Switch Fabric Module (SFM or SFM2) sets up and tears down flow connections, monitors switch operation, and performs switch functions. The I/O modules use the SFM processors to perform routing functions, including resolution of unknown addresses, route determinations, protocol processing, and other exception events.

Each module provides 10-Gbps switch control element for switching functionality and flow processing for four I/O modules. You can install a second active module to service four additional I/O modules. Both active modules are on simultaneously in the CSS 11800. The chassis enables you to configure two additional passive modules for redundancy. Therefore, you can configure a total of four SFMs or SFM2s in a chassis, of which only two would be active at any time.

Note When the CSS 11800 contains two passive SFMs and an active SFM switchover occurs, both passive SFMs switchover to become active SFMs.

You can mix SFMs with SFM2s in the same CSS 11800 chassis. However, you must use the same type module as the active SFM and as the passive SFM.

The Switch Fabric Module (SFM and SFM2) contains Power, Status, and Active LEDs. The SFM has four RJ-45 RS-232 Console and Diag connectors (all of these connectors are reserved for field service diagnostic use only).
