Figure 22: Installing a Redundancy Midplane
To install the I/O modules in a redundancy group:
Install the redundancy I/O module in the lowest-numbered slot of the redundancy
1.
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.
Install the corresponding I/O module for the line module of each slot in the redundancy
2.
group. (See "Installing a Line Module or an I/O Module" on page 39.)
Cable each module to provide a path to the remote interface. (See "Cabling ERX
3.
Routers" on page 47.)
To verify that the installation is complete:
After you have cabled the system for power, as described in "Cabling ERX Routers"
1.
on page 47, turn on the power switches.
