To replace a Routing Engine on node 0 of a chassis cluster using a USB flash drive:
1. Prepare to shut down node 0:
a. Perform a manual failover of the redundancy groups (RGs) from node 0 to node 1.
Fail over RG1:
root@node0> request chassis cluster failover redundancy-group 1 node 1
Fail over RG0:
root@node0> request chassis cluster failover redundancy-group 0 node 1
b. Verify that both RGs are active on node 1 after the failover:
root@node0> show chassis cluster status
{secondary:node0}
root@node0> show chassis cluster status
