Installing Components for Line Module Redundancy
ERX Edge Routers
3-15
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.
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 Modules and Their I/O Modules , earlier in this chapter).
Installing the Redundancy Midplane
To install the redundancy midplane in a redundancy group:
Caution: If you do not use the halt command before removing or powering down
an SRP, the system’s NVS card may become corrupted.
1
Enter the halt command.
See ERX System Basics Configuration Guide, Chapter 5, Managing
Line Modules and SRP Modules for information about the halt
command.
Warning: Turn off the ERX system before you install the redundancy midplane.
Working inside the ERX system when it is on can lead to electric shock and serious
burns.
2
Turn off the power switches located on the power input module in
the rear of the system (see
Figure 3-11 ).
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
Figure 3-11 ).
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.
