Resetting QAM Modulators Through the auditQam Utility
The reset option of the auditQam utility allows you to reset a QAM 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 next
in this section.

Resetting a Few QAM Modulators
If you want to reset only a few modulators, complete this procedure for each
modulator.
1 If necessary, open an xterm window on the DNCS.
2 Type the following command and press Enter:
modulator.
1 If necessary, open an xterm window on the DNCS.
2 Type the following command and press Enter:
auditQam -reset [QAM ip address]
Result: The system shuts down and reinitializes the modulator.
Note: The system also performs an audit to ensure that the session list for the
modulator matches the session list from the DNCS.

Resetting Many QAM Modulators
When performing an upgrade, you often do not want to manually reset hundreds of
modulators from the DNCS GUI. To save time, you can create a script that resets the
QAMs. Refer to the example on the following page for a sample script.

QAMs. Refer to the example on the following page for a sample script.
This sample script will reset four QAMs, wait for 5 minutes (sleep 300 seconds), and
then ping the units to verify that they are responsive. The ping is followed by a 60
second waiting period to allow the QAMs to fully provision on the system. The
script will then continue in the same manner to update the other QAMs in the
network.

Important! Use the Monitoring Remote QAM Resets (on page 25) procedure when
resetting QAMs using an auditQam script to reset multiple QAMs.

Note: You can save and re-use this script each time you need to reboot your QAMs.
