Installing Components for Line Module Redundancy

A spare line module provides redundancy for a group of identical line modules for ERX-7xx and ERX-14xx models only.

Note: The ERX-310 router does not support line module redundancy.

For line module redundancy to operate, you must install:

The line modules, including the spare line module
The redundancy midplane
The I/O modules, including the spare I/O module

For more information, see Redundancy Features.

Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the router is on. Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. These actions can prevent electric shock and serious burns.

Caution: When handling modules, use an antistatic wrist strap connected to the router'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.
