Chapter 7: Maintenance

Device upgrade

Before upgrading the device, ensure that you download the latest software, the distribution package
and the settings file, on the file server. You can perform the device upgrade in the following ways:
• Automatic: You can configure the device to poll periodically for a newer version of the software
in the file server and automatically download the software and upgrade itself.
• Manual: You can upgrade the device without the device waiting for a polling interval by:
- Using the update option in the Settings app on the device. With the update option, the
device immediately downloads and installs the software if an updated version is available.
- Rebooting the device from the Settings app or from System Manager. With rebooting, the
device might upgrade immediately or later based on the upgrade policy configured for the
device.

Device upgrade process

The upgrade event is logged under NOTICES level in the Syslog file. During boot up, the 9600
Series IP Deskphones performs the following tasks:
1. The phone receives the file server address from DHCP, LLDP, or the device interface.
2. The phone connects to the file server and searches for the upgrade file depending on the
SIG parameter value.
• 0: Default, 96x1Supgrade.txt
• 1: H.323, 96x1Hupgrade.txt
• 2: SIP, 96x1Supgrade.txt
3. The phone compares its software version with the version specified in the upgrade file.
• For Sonic and other hardware phones, HWVER value is also checked when the MODEL4
match is found.
4. The phone then downloads the upgrade file for parsing. The parameter
UPGRADE_FILE_EXECUTION_STATUS is updated with the following values upon parsing:
• 0: Upgrade file is downloaded and parsed.
