Remove the FEB

To remove the FEB, follow this procedure (see Figure 28):

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. Pull the ends of the ejector levers (located at each end of the unit) outward until they are nearly perpendicular to the faceplate of the FEB.
7. Grasp the ejector levers and pull firmly to slide the FEB about halfway out of the chassis.
8. Place one hand under the FEB to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

   When the FEB is out of the chassis, do not hold it by the ejector levers. They cannot support its weight. Do not stack the FEB on top of or under other components after removal. Place it individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
