Installing the Redundancy Midplane

Caution: When handling modules, use an antistatic wrist strap connected to the
ERX system's ESD grounding jack, and hold modules by their edges. Do not touch
the components, pins, leads, or solder connections. These actions help to protect
modules from damage by electrostatic discharge.
To install the line modules in a redundancy group:
1
Install the spare line module in the lowest-numbered slot of the
redundancy group.
2
Install the other line modules in the remaining slots. (See
Line Modules and Their I/O
To install the redundancy midplane in a redundancy group:

3
Remove the I/O modules from the slots that the redundancy
midplane will span.
4
Place the redundancy midplane in the chassis so that it rests against
the guides below the chassis midplane (see
5
Align the screw holes in the redundancy midplane with the screw
holes in the guides so that the midplane covers the slots for the
redundancy group.
6
Using a Phillips screwdriver and the screws provided, loosely attach,
but do not tighten, the redundancy midplane to the guides.
