Verifying And Configuring The Upgraded Cb-Re As The Master; Verifying And Configuring The Upgraded Cb-Re As The Backup - Juniper MX2020 Hardware Manual

The CB-RE might require several minutes to boot. After the CB-RE boots, verify that it is installed correctly
by checking the FAIL, RE0, and RE1 LEDs on the craft interface. If the router is operational and the CB-RE
is functioning properly, the green ONLINE LED on the CB-RE lights steadily. If the red FAIL LED on the
CB-RE lights steadily instead, remove and install the CB-RE again. If the red FAIL LED still lights steadily,
the CB-RE is not functioning properly. Contact your customer support representative.

Verifying and Configuring the Upgraded CB-RE as the Master

After replacing the backup CB-RE with the REMX2K-X8-64G CB-RE, perform the following steps:
1. Verify that the REMX2K-X8-64G CB-RE is online by issuing the show chassis hardware and show
chassis routing-engine |no-more commands.
Verify the software by using the show vmhost status and show vmhost version commands.
2. After you install the REMX2K-X8-64G CB-RE, the CB-RE is automatically powered on and comes up
in amnesiac mode as it is loaded with factory defaults. After the CB-RE comes up in amnesiac mode,
load the base configuration and commit.
3. Configure the backup CB-RE by using the commit synchronize command to copy the configuration to
the backup CB-RE.
4. Use the request chassis routing-engine master switch command to make the REMX2K-X8-64G CB-RE
(RE1) the master CB-RE. All FPCs reboot after this step.

Verifying and Configuring the Upgraded CB-RE as the Backup

REMX2K-X8-64G CB-RE (RE0) the backup CB-RE.
2. Use the commit synchronize command to copy the active configuration from the master CB-RE to the
