Remove the Routing Engine

To remove the Routing Engine, follow this procedure (see Figure 42):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. On the console or other management device connected to the Routing Engine, enter CLI operational mode and issue the following command to shut down the router software cleanly and preserve Routing Engine state information.
   user@host> request system halt

   Wait until a message appears on the console confirming that the operating system has halted.

   For more information about the command, see the JUNOS Internet Software Operational Mode Command Reference: Protocols, Class of Service, Chassis, and Management.

3. Press the power switch for both power supplies to the OFF (0) position. On both AC and DC power supplies, the switch is located on the power supply faceplate.
4. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Prevent Electrostatic Discharge Damage.
5. Using a Phillips screwdriver, loosen and remove the five screws that secure the Routing Engine cover to the FEB faceplate (the cover is shown in Figure 3). Pull the cover straight off the Routing Engine. Save the screws.
6. Using your thumbs, push and hold the red tab on each extractor clip toward the outer edge of the unit. Push the ends of the extractor clips outward to unseat the Routing Engine from the chassis.
7. Grasp the extractor clips and slide the unit about halfway out of the chassis.

   Slide the Routing Engine straight out of the chassis. Damage can result if it gets lodged because of uneven movement.

8. Place one hand under the Routing Engine to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
