Removing the Rear Component Cover

The rear component cover protects the SFMs, Routing Engines, MCSs, and PCGs, as shown in Figure 2. To remove it, follow this procedure:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Loosen the thumbscrew at each corner of the component cover, using a Phillips screwdriver if necessary.
3. Pull the cover straight off the chassis.

To maintain proper airflow and provide electromagnetic shielding, do not operate the router without the rear component cover in place.
