The C4 CMTS is now operating with SCM 3s and its configuration file is backupMMDDYY.cfg. It is running on Release 8.x.x.x
software, which has been committed. If the image currently on the SCM cards is not the desired load, then upgrade to the
desired load using the normal upgrade procedure. Refer to the Release Notes for more information.
Note: By default, the SCM 3 out-of-band Ethernet cable connection defaults to using the rear PIC connection.
