Installing Components for Line Module Redundancy ! 51
Chapter 5: Installing Modules
Installing the Redundancy Midplane
To install the redundancy midplane in a redundancy group:
1. Enter the halt command.
See JUNOSe System Basics Configuration Guide, Chapter 5, Managing Line
Modules and SRP Modules for information about the halt command.
2. Turn off the power switches located on the power input module in the rear of
the system (see Figure 27).
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 27).
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.
7. Carefully insert an I/O module in one slot to ensure that the redundancy
midplane is aligned correctly; then tighten the screws.
CAUTION: If you do not use the halt command before removing or powering down
an SRP, the system’s NVS card may become corrupted.
WARNING: Turn off the E-series router before you install the redundancy midplane.
Working inside the router when it is on can lead to electric shock and serious
burns.
CAUTION: A misaligned redundancy midplane can result in bent pins on the
backplane and midplane and poor contact between the I/O modules and the
redundancy midplane.
