Removing an MX480 Routing Engine

Before you remove a Routing Engine, remove the cables that connect to it.

CAUTION:

Before you replace a Routing Engine, you must take the host subsystem offline. If there is only one host subsystem, taking the host subsystem offline shuts down the router.

CAUTION:

If the Routing Engine to be replaced is currently functioning as the master Routing engine, switch it to be the backup before removing it.

To remove a Routing Engine from an SCB (see Figure 1):

  1. Take the Routing Engine offline gracefully.
  2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  3. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  4. Verify that the Routing Engine LEDs are off.
  5. Loosen the captive screws on the top and bottom of the Routing Engine.
  6. Flip the ejector handles outward to unseat the Routing Engine.
  7. Grasp the Routing Engine by the ejector handles, and slide it about halfway out of the chassis.
  8. Place one hand underneath the Routing Engine to support it, and slide it completely out of the chassis.
  9. 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.

Figure 1: Removing a Routing Engine Removing a Routing Engine

Installing an MX480 Routing Engine

To install a Routing Engine into an SCB (Figure 2):

  1. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  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.
  4. Carefully align the sides of the Routing Engine with the guides inside the opening on the SCB.
  5. Slide the Routing Engine into the SCB until you feel resistance, and then press the Routing Engine's faceplate until it engages the connectors.
    CAUTION:

    Align the Routing Engine correctly to avoid damaging it.

  6. Press both of the ejector handles inward to seat the Routing Engine.
  7. Tighten the captive screws on the left and right of the Routing Engine.
  8. Connect the management device cables to the Routing Engine.

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 lights steadily. If the red FAIL LED 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.

To check the status of the Routing Engine, use the CLI command:

For more information about using the CLI, see the Junos OS documentation.

Note:

If enhanced IP network services is configured on the chassis, all routing engines must be rebooted after synchronizing the routing engines. For more information on synchronizing the routing engines, see Synchronizing Routing Engines.

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

A redundant host subsystem consists of a primary 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 primary 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 or SCBE3 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-MX or Upgrading an MX960 to Use the SCBE2-MX, depending on the chassis on which the Routing Engine is being upgraded. To upgrade the Switch Control Board to SCBE3 Upgrading an MX240, MX480, or MX960 Router to Use the SCBE3-MX.

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 10, Figure 11, and Figure 12):

  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.
