Removing FEBs
Six FEBs are installed in the router. The FEBs are located in the rear of the chassis in the
slots marked FEB0 through FEB5. Each FEB weighs approximately 4.5 lb (2.0 kg).
To remove the FEBs (see Figure 33 on page 132):
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 an approved site ESD grounding point. See the instructions for your site.
3. Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector
handles on each side of the FEB faceplate.
4. Flip the ejector handles outward to unseat the FEB.
5. Grasp both ejector handles, pull firmly, and slide the FEB about three-quarters of the
way out of the chassis.
6. Place one hand underneath the FEB to support it and slide it completely out of the
chassis. Place it on the antistatic mat.
