8.4.6.1.2 Software Upgrade Wizard Guided Procedure
To use the Software Upgrade Wizard take the following steps:
Note:
Note:
1. Stop all traffic on the device (refer to the note above.)
2. From the main menu list on the left, click on the Software Update link. The Software
Upgrade screen with the sub-menu bar on the top is displayed. (Figure 8-48)
Version SN09
For release prior to 5.0, it is recommended to always use a
unique filename when downloading CAS files to the MG3200 gateway. For
example, alter the filename by including a unique release identifier, date time
string, or other meaningful text. Failure to do so will result in difficulty
managing the CAS files due to having several entries with the same name in
the CAS file selection box which may or may not be functionally identical.
For this reason, for the case if a new CAS file is to be loaded during the
software upgrade, ensure to rename the file after placing it on user's PC.
(Note: This is not applicable if existing CAS file is to be re-used).
The Software Upgrade Wizard requires the device to be reset at the end of
the process, which disrupts any existing traffic on the device. To avoid
disrupting traffic, disable all traffic on the device before initiating the Software
Upgrade Wizard. Traffic should be disabled/diverted off the MG 3200 from
the Call Server side by the customer. Refer to Appendix – Disable MG 3200
Traffic Prior to Software Upgrade on page 405.
It is recommended to perform the upgrade when low call traffic is known to
occur.
