Resetting Modulators Through the auditQam Utility
The reset option of the auditQam utility allows upgrade engineers to reset a
modulator from the command line of the DNCS, a process that is usually quicker
than resetting the modulator through the DNCS GUI or modulator panel. If you
have only a few modulators to reset, you can just type the IP address of the
modulator as an argument to the auditQam -reset command. If you have many
modulators to reset, consider creating a script. Instructions and guidelines for both
situations follow.

Upgrade engineers frequently do not have time to manually reset hundreds of
modulators from the DNCS GUI. To save time, engineers can create a script that
runs automatically. Refer to the following example for a sample script.
auditQam -reset 123.123.123.123
auditQam -reset 123.123.123.123
sleep 1
auditQam -reset 123.123.123.124

Resetting a QAM interrupts all active sessions on the QAM for up to 10 minutes.
Complete this task during a maintenance period whenever possible.
