Returning the SCB

The SCB is field-replaceable and hot-pluggable. You can remove and replace it without powering down the system; however this causes major impact to the system. While the SCB is out of the router, route lookups, system component monitoring, exception and control packet transfer, and FPC operation monitoring cannot occur.

Action

To return the SCB, see Return the Failed Component, or the return procedure in the M40 Internet Router Hardware Guide.
