Installing the I/O Modules

To install the I/O modules in a redundancy group:
1.
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.
3.
Install the redundancy I/O module in the lowest-numbered slot of the
redundancy group.
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" on
page 44, earlier in this chapter.)
Cable each module to provide a path to the remote interface (see "Cabling
E-series Routers" on page 51).
