f. If any scripts are referenced in the configuration, then back up these scripts:
root@node0# scp /var/db/scripts/commit/commit-script.slax root@node1-fxp0-ip:
/commit-script.slax
4. Install the replacement Routing Engine:
a. Power off node 0:
root@node0> request system power-off
b. Wait until a message appears on the console confirming that the services have stopped, and then
physically turn off the power.
c. Label and disconnect all the cables connected to node 0.
d. Replace the Routing Engine.
e. To prevent a split-brain scenario (where the control link is connected while both the nodes are in
the primary state), reconnect only the console cable and the cable to the fxp0 interface. Leave the
rest of the cables disconnected.
f. Ensure that the status of the control link and fabric link on node 1 is down:
