Installing the I/O Modules
To install the I/O modules in a redundancy group:
1
Install the redundancy I/O module in the lowest-numbered slot of
the redundancy group.
Caution: When setting up a redundancy group with line modules, be sure to install
the redundancy I/O module in the lowest-numbered slot of the redundancy group.
It is possible to install the redundancy I/O module in other slots; however, doing so
may damage other I/O modules connected to the redundancy midplane.
2
Install the corresponding I/O module for the line module of each slot
in the redundancy group. (See
Installing a Line Module or an I/O
Module , earlier in this chapter.)
3
Cable each module to provide a path to the remote interface (see
Chapter 6, Cabling E-Series Routers ).
