Upgrading to the RE-S-X6-64G Routing Engine in a Redundant Host Subsystem

 

A redundant host subsystem consists of a master Routing Engine (RE0) and a backup Routing Engine (RE1). To upgrade the host subsystem to use the RE-S-X6-64G Routing Engine, you must first uninstall the backup Routing Engine and install the RE-S-X6-64G Routing Engine, which then becomes the backup Routing Engine. You then switch over this backup Routing Engine to make it the master Routing Engine. Replace the other Routing Engine and configure it as the backup Routing Engine.

Ensure that the Switch Control Board in the chassis is SCBE2 because the RE-S-X6-64G Routing Engine is not compatible with the Switch Control Boards SCB or SCBE. To upgrade the Switch Control Board to SCBE2, see Upgrading an MX240 to Use the SCBE2-MX, Upgrading an MX480 to Use the SCBE2-MXor Upgrading an MX960 to Use the SCBE2-MX, depending on the chassis on which the Routing Engine is being upgraded.

Note

Save the router configuration before proceeding with the Routing Engine upgrade.

Note

Nonstop active routing (NSR) and graceful Routing Engine switchover (GRES) are not supported during the upgrade and they must be temporarily disabled. Disable NSR by removing the nonstop-routing statement from the [edit routing-options] hierarchy level and by removing the graceful-switchover statement from the [edit chassis redundancy] hierarchy level .

Removing the Routing Engine

To remove the backup Routing Engine from the chassis (see Figure 1, Figure 2, and Figure 3):

  1. On the external management device connected to the Routing Engine, shut down the host subsystem by using the request system power-off command.
  2. Wait until a message appears on the console confirming that the operating system has halted.
  3. Remove the cables connected to the Routing Engine.
  4. Place an electrostatic bag or antistatic mat on a flat, stable surface. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  5. Verify that the Routing Engine LEDs are off. Loosen the captive screws on the top and bottom of the Routing Engine.
  6. Grasp the Routing Engine by the ejector handles, and slide it about halfway out of the chassis.
  7. Place one hand underneath the Routing Engine to support it, and slide it completely out of the chassis. Place the Routing Engine on the antistatic mat.
Note

To maintain proper airflow through the chassis, do not leave an SCB installed in the chassis without a Routing Engine for extended periods of time. If a Routing Engine is removed, a replacement Routing Engine should be installed as soon as possible.

Installing the Routing Engine RE-S-X6-64G

To install the Routing Engine RE-S-X6-64G:

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Ensure that the ejector handles are not in the locked position. If necessary, flip the ejector handles outward.
  3. Place one hand underneath the Routing Engine to support it and carefully align the sides of the Routing Engine with the guides inside the opening on the Switch Control Board SCBE2.Note

    The Routing Engine RE-S-X6-64G is supported only on the SCBE2. RE-S-X6-64G is not compatible with the SCB or the SCBE.

  4. Slide the Routing Engine into the SCBE2 until you feel resistance, and then press the Routing Engine's faceplate until it engages the connectors.
  5. Press both of the ejector handles inward to seat the Routing Engine. Tighten the captive screws on the top and bottom of the Routing Engine.
  6. Connect the management device cables to the Routing Engine. After the Routing Engine is installed, the ONLINE LED starts blinking green slowly.
  7. Replace the former master Routing Engine, RE0, with the Routing Engine RE-S-X6-64G. Note

    The Routing Engine RE-S-X6-64G is supported only on the SCBE2. RE-S-X6-64G is not compatible with the SCB or the SCBE.

The Routing Engine might require several minutes to boot. After the Routing Engine 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 Routing Engine is functioning properly, the green ONLINE LED on the Routing Engine lights steadily. If the red FAIL LED on the Routing Engine lights steadily instead, remove and install the Routing Engine again. If the red FAIL LED still lights steadily, the Routing Engine is not functioning properly. Contact your customer support representative.

Verifying and Configuring the Upgraded Routing Engine as the Master

After replacing the backup Routing Engine with the RE-S-X6-64G Routing Engine, perform the following steps:

  1. Verify that the SCBE2 and RE-S-X6-64G Routing Engine are online by issuing the show chassis hardware command.
  2. After you install the RE-S-X6-64G Routing Engine into the SCBE2, the Routing Engine gets automatically powered on and comes up in amnesiac mode as it is loaded with factory defaults. After the Routing Engine comes up in amnesiac mode, load the base configuration and commit.
  3. Configure the backup Routing Engine by using the commit synchronize command to copy the configuration to the backup Routing Engine.
  4. Use the request chassis routing-engine master switch command to make the Routing Engine RE-S-X6-64G (RE1) the master Routing Engine. All FPCs reboot after this step.

Verifying and Configuring the Upgraded Routing Engine as the Backup

  1. Use the request chassis routing-engine master switch command to make newly installed RE-S-X6-64G (RE0) the backup Routing Engine.
  2. Use the commit synchronize command to copy the active configuration from the master Routing Engine to the backup Routing Engine.
