Chapter 2 Cabling the CSS
Cabling the CSS 11800 Modules
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).
