Attaching Ferrite Clamp to the Alarm Cable

You must attach the Cisco-specified ferrite clamp on the alarm cables for the CGR 1120 routers to meet EMC standards to reduce unwanted electromagnetic noise on the system.

Note: All alarm cables used on the CGR 1120 must be those specified by Cisco.

On the CGR 1120

1. Power to the CGR 1120 must be off when attaching the ferrite clamp to the alarm cable.

2. If the alarm cable is not already attached to the front panel, plug the alarm cable into the RJ45 Alarm Port on the panel (Alarm Port on CGR 1120).

3. Snap the ferrite clamp on the alarm cable, placing the clamp as close to the end of the RJ45 connection as possible. ( Ferrite Clamp)
