CHAPTER 3
Installing ERX Modules
3-16
7 Carefully insert an I/O module in one slot to ensure that the
redundancy midplane is aligned correctly; then tighten the screws.
A misaligned redundancy midplane can result in bent pins on the
boards and poor contact between the I/O modules and the
redundancy midplane.
Figure 3-11 Installing a redundancy midplane
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 or I/O Module,
earlier in this chapter.)
