Description (partial)

Symptom:<B/> When Return Material Authorization (RMA) replacement of a Cisco uBR-MC20X20V line card occurs, some downstream channels may come up as rf-shutdown, even though the previously functional line card in the same slot has the configurations using no rf-shutdown command.

As a consequence, cable modems that were previously online might not be able to register successfully again, until a no rf-shutdown command is executed again on these channels. If line card high-availability (LC HA) is configured, the RMA would have caused an line card  switchover. When an line card revertback occurs,, the channels will be shutdown and cable modem connectivity will be lost.

Conditions:<B/> This issue occurs on the RMA of a linecard. This occurs only if a Cisco uBR-MC20X20V line card is ordered with a 0DS/5DS/license, and later upgraded by purchasing additional downstream licenses.
