Removing a Half-Height NLC
To remove a half-height NLC from the Cisco 6400 chassis:
Step 1 Attach an ESD-preventive strap between you and the chassis surface.
Step 2 Remove any connections to the modules. Be sure to cover any fiber-optic connections to prevent
contamination from moisture or dirt.
Step 3 Loosen the two (top and bottom) cross-slotted screws securing the NLC metal carrier to the full-height
carrier.
Step 4 Grasp the two lever handles on the NLC, and gently pull the handles away from the carrier unit to
loosen the unit.
Step 5 Carefully slide the NLC out of the full-height carrier. Avoid damaging the connectors on the rear of the
plug-in unit.
Step 6 Place the NLC on an antistatic surface.
