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 can 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” on page 44.)

3.Cable each module to provide a path to the remote interface. (See “Cabling ERX Routers” on page 53.)
