Removing and Installing a CSC or SFC
Caution All four sides of the air filter door are lined with EMI-preventive gaskets consisting of many raised,
conductive contacts. Align and seat the door carefully to avoid damaging the EMI-preventive gasket
contacts. A damaged gasket can result in reduced EMI performance.
Step 2 Push firmly on the air filter door until it is seated in the opening of the switch fabric and alarm card cage,
then tighten the two captive screws in each.
Caution Be careful not to damage the honeycomb screen on the back of the air filter door and on the inside of the
switch fabric and alarm card cage. Damaging the honeycomb screen can restrict the air flow and cause
overheating in the router, and it can diminish EMI protection.
