Removing the SRX5800 Services Gateway Routing Engine

Caution: Before you replace a Routing Engine, you must take the host subsystem offline.

To remove the Routing Engine (see Figure 56):

  1. Take the host subsystem offline as described in Taking the SRX5800 Services Gateway Host Subsystem Offline.
  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 strap to one of the ESD points on the chassis.
  4. Loosen the captive screws at each end of the Routing Engine faceplate.
  5. Flip the ejector handles outward to unseat 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.
  8. Place the Routing Engine on the antistatic mat.

Installing the SRX5800 Services Gateway Routing Engine

If you install only one Routing Engine in the services gateway, you must install it in the slot in the front panel of SCB0. If you install a second routing engine to use the dual chassis cluster control link feature, you install it in the slot in the front panel of SCB1.

To install a Routing Engine into an SCB (see Figure 57):

  1. If you have not already done so, take the host subsystem offline. See Taking the SRX5800 Services Gateway Host Subsystem Offline.
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Ensure that the ejector handles are not in the locked position. If necessary, flip the ejector handles outward.
  4. Place one hand underneath the Routing Engine to support it.
  5. Carefully align the sides of the Routing Engine with the guides inside the opening on the SCB.
  6. Slide the Routing Engine into the SCB until you feel resistance, and then press the Routing Engine's faceplate until it engages the connectors.
  7. Press both of the ejector handles inward to seat the Routing Engine.
  8. Tighten the captive screws on the top and bottom of the Routing Engine faceplate.
  9. Power-on the services gateway.

The Routing Engine might require several minutes to boot.

After the Routing Engine boots, verify that it is installed correctly by checking the RE0 and RE1 LEDs on the craft interface. If the services gateway 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
Routing Engine status:
  Slot 0:
    Current state                  Master ... 

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