50 ! Installing Components for Line Module Redundancy
Installing Components for Line Module Redundancy
A spare line module provides redundancy for a group of identical line modules for
ERX-7xx/14xx models only.
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 in Chapter 1, E-series Overview.
Installing the Line Modules
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 Installing Line and I/O
Modules earlier in this chapter).
NOTE: The ERX-310 router does not support line module redundancy.
WARNING: Do not insert any metal object, such as a screwdriver, or place your
hand into an open slot or the backplane when the E-series router is on. Remove
jewelry (including rings, necklaces, and watches) before working on equipment
that is connected to power lines. These actions prevent electric shock and serious
burns.
CAUTION: When handling modules, use an antistatic wrist strap connected to the
E-series 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.
