3.Align the rear of the MCS with the guides inside the chassis and slide it in completely.

4.Press the extractor clip at each end of the MCS inward.

5.Verify that the green LED labeled OK on the MCS faceplate is lit. Also check the host module LEDs on the craft interface to verify that the green LED labeled ONLINE is lit for the host module to which the MCS belongs (Figure 11 shows the LEDs).

You can also verify correct MCS functioning by issuing the

show chassis environment mcs command described in Maintaining Host Module Components on page 131.

6.Reinstall the rear component cover and tighten the thumbscrew at each corner to secure it to the chassis. For complete instructions, see “Reinstalling the Rear Component Cover” on page 109.

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