VSG-1200 V2 User's Guide 30.3 Scheduled Firmware Upgrade You can set the VSG to automatically check and download a new firmware from a TFTP server. This allows you to automate the firmware upgrade process if you have more than one VSG on your network. A synchronization file contains information on firmware version and filename. A sample synchronization file is shown next. Figure 146 Scheduled Firmware Upgrade: Synchronization File Example You have to manually download the latest firmware from www.zyxel.com to the TFTP server and update the synchronization file. Figure 147 Scheduled Firmware Upgrade Example The following describes the automatic firmware upgrade process. 1 The VSG checks the synchronization file on the TFTP server for the firmware version number. 2 If the synchronization file has the latest firmware version number, VSG retrieves the latest firmware file as specified in the synchronization file. 3 VSG upgrades the firmware and restarts. Note: During the firmware upgrade process, the VSG disconnects all subscriber Internet access. Subscribers need to log in again. Click System Tools, Firmware and click the Scheduled Firmware Upgrade link to display the screen as shown next. Figure 148 Firmware: Scheduled Upgrade Chapter 30 Firmware 204
