Back-up the existing configuration with the following command:
copy running-config verbose /system/cfgfiles/backupMMDDYY.cfg
3.
FTP the configuration off the CMTS and save it on a local machine / server. The configuration will be required later.
4.
Power down the C4 CMTS.
5.
Remove the SCM or SCM-II cards from the chassis.
6.
If out-of-band access is used and the Ethernet cables were connected to the front of the old SCM, reconnect them to
the front of the new SCM 3 (or reconnect them to the rear PIC because the SCM 3 will use the rear SCM PIC port for
OOB by default).
7.
Out-of-band SCM Ethernet access defaults to the rear SCM PIC. Depending on your environment, you can choose to
connect to the rear SCM PIC or use step below to use the front Ethernet connector. If you choose to move the cables
to the rear SCM PIC, go to step . If Ethernet cables are used and will remain connected to the front port, continue with
step 8.
8.
Insert the SCM 3 card in slot 19 and connect serial console cable and the front Ethernet cable.
9.
To change the default operation to use the front port, power up the chassis with the SCM 3 card in slot 19. See the
sample bootloader script below. Using the example below, respond as instructed.
