UPGRADING AND PROVISIONING GAC2500 supports software upgrade via TFTP /HTTP/HTTPS server. Please go to Maintenance Upgrade to configure. GAC2500 supports the following upgrade modes: • Manual upload firmware file to upgrade • Upgrade via TFTP firmware server • Upgrade via HTTP/HTTPS firmware server Upgrade and Provisioning Configuration There are two ways to setup upgrade and provisioning on GAC2500. They are Keypad Menu and Web GUI.
Figure 12: GAC2500 Upgrade Configuration via Web GUI Upload Firmware Locally If there is no HTTP/TFTP server, users could also upload the firmware to the GAC2500 directly via Web GUI. Please follow the steps below to upload firmware to GAC2500 locally. 2. Note: It is HIGHLY recommended that use an Uninterruptible Power Supply (UPS) or it might be fail if emergency cutoff occurs in the process of update. Please unpack the compression package before upgrade when manual update. 3.
1. Select the firmware file from your PC. Then uploading progress will show at the button where it was "Upload" in the above step. 2. When uploading is done, users can see the upgrading process starts on the GAC2500 LCD. 3. The phone will reboot again with the new firmware version upgraded. Figure 13: Upload Firmware Locally No Local Firmware Servers Service providers should maintain their own firmware upgrade servers.
Provisioning and Configuration File Download Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP or HTTP/HTTPS. The "Config Server Path" is the TFTP, HTTP or HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The "Config Server Path" can be the same or different from the "Firmware Server Path".
