Understanding the Host Module ! 343
Chapter 25: Monitoring the Host Module
One or two host modules can be installed into the midplane from the rear of the
chassis (see Figure 142). The Routing Engine (slot
RE0) is below the MCS slot
(
MCS0), while slot RE1 is above the MCS1 slot. RE0 must use MCS0 and RE1 must
use
MCS1 or the circuit will not be connected.

This chapter provides basic information about monitoring the Routing Engine and
the MCS. For more detailed information about monitoring the Routing Engine, see
“Monitoring the Routing Engine” on page 125. For more detailed information about
monitoring the MCS, see “Monitoring the MCS” on page 359.
