M40e Miscellaneous Control Subsystem (MCS) Description

The LED Indicates disk activity for the internal IDE interface. It does not necessarily
HD
indicate routing-related activity.
NOTE: The LEDs that report host module status (including Routing Engine
status) are on the craft interface rather than the Routing Engine faceplate.
The Miscellaneous Control Subsystem (MCS) works with its companion Routing Engine
to provide control and monitoring functions for router components. It also generates a
clock signal for the SONET/SDH interfaces on the router.
One or two host modules (paired MCS and Routing Engine) can be installed into the
midplane from the rear of the chassis, as shown in "M40e Chassis Description" on page 8.
Only one host module is active at a time, with the optional second host module in standby
mode. For more information about host module interdependence and redundancy, see
"M40e Host Module Description" on page 23.
