Installing an MX960 Routing Engine

 

To install a Routing Engine into an SCB (Figure 1):

  1. Ensure that the ejector handles are not in the locked position. If necessary, flip the ejector handles outward.
  2. Place one hand underneath the Routing Engine to support it.
  3. Carefully align the sides of the Routing Engine with the guides inside the opening on the SCB.
  4. 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.

  5. Press both of the ejector handles inward to seat the Routing Engine.
  6. Tighten the captive screws on the top and bottom of the Routing Engine.
  7. 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:

user@host> show chassis routing-engine

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.
