5  If you are upgrading more than one GoQAM, establish an order for upgrading 
the modulators. 
6  Install the GoQAM software onto the DNCS from either the Cisco FTP site or a 
CD. 
 
Upgrade Tasks 
Important:
 Performing the upgrade tasks will result in a temporary loss of service as 
modulators are reset. 
1  Download the new software to the modulators. 
2  If the modulators you are upgrading currently carry broadcast sessions, 
determine the sessions that are running on those modulators you plan to 
upgrade. This will allow you to verify that these sessions are rebuilt after the 
new software is downloaded to the modulators. 
3  Verify that the upgraded modulator is functioning properly. 
Important: Read and follow the directives contained in 
Impact of TVs with 
QAM Tuners (on page 9). 
4  After the upgrade is complete, generate a Doctor Report using the –av option to 
verify system stability and functionality. 
5  Perform System Validation Tests for your system release version.
