Removing the Routing Engine from an M7i Router

To remove the Routing Engine (see Figure 8):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
3. Press and hold the offline button on the faceplate of the Routing Engine until the green ONLINE LED turns off, which takes about 5 seconds.
4. Loosen the thumbscrews securing the Routing Engine, using a Phillips screwdriver if necessary.
5. Grasp the handle and slide the unit about halfway out of the chassis.

   Caution: Be careful to slide the Routing Engine straight out of the chassis. Damage can result if the Routing Engine gets lodged because of uneven movement.

6. 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.
