Verifying The Upgrade And Configuring The Upgraded Routing Engine; Upgrading To The Re-Ptx-X8-64G Routing Engine In A Nonredundant Host Subsystem - Juniper PTX5000 Hardware Manual

4. Carefully align the sides of the Routing Engine with the guides inside the opening on the Control
Board.
5. Slide the Routing Engine into the chassis until you feel resistance, and then press the Routing
Engine's faceplate until it engages the connectors.
6. Press both the ejector handles inward to seat the Routing Engine.
The Routing Engine might require several minutes to boot. If the router is powered on and the
Routing Engine's corresponding Control Board is functioning normally, the Routing Engine comes

8. The Routing Engine RE1 comes up as the backup Routing Engine.

Verifying the Upgrade and Configuring the Upgraded Routing Engine

Configure the upgraded Routing Engine:
1. You then switch over this backup Routing Engine to make it the primary Routing Engine. Use the
request chassis routing-engine master (acquire | release | switch) command to switchover the RE1-CB1
to become primary host subsystem. All FPCs reboot after this step.
2. Replace the Routing Engine RE0 with the RE-PTX-X8-64G Routing Engine.
3. Use the request chassis routing-engine master (acquire | release | switch) command to make the Routing
Engine RE0 as the backup Routing Engine.
4. Configure the new backup Routing Engine RE0 by using the commit synchronize command to copy the
configuration to the backup Routing Engine.
