The host module constructs routing tables, performs system management functions,
and generates the SONET/SDH clock signal for SONET/SDH interfaces. It consists of a
paired Routing Engine and Miscellaneous Control Subsystem (MCS).
For a host module to function, both of its components—Routing Engine and MCS—must
be installed and operational. One or two host modules can be installed into the midplane
from the rear of the chassis, as shown in "M40e Chassis Description" on page 8. The
Routing Engine slot labeled
is above the MCS 1 slot.
If two host modules are installed, both are powered on, but only one is active (the master);
the second host module is in standby mode and performs no functions. By default, the
master host module is the one with components installed in the
To change the default master Routing Engine, include the appropriate
