Firmware Upgrading
Similar to configuration file provisioning, GXV3370 supports downloading firmware file via
HTTP/HTTPS/TFTP. The firmware file is encrypted and GXV3370 ensures only authentic, signed and
untampered firmware file can run. Here are the recommended settings for firmware downloading.
Figure 22: GXV3370 Firmware Upgrade Configuration
- Firmware Upgrade Mode: HTTPS.
HTTPS is recommended so the traffic is encrypted while travelling through the network.
- HTTP/HTTPS User Name and Password:
This can be set up as required on the provisioning server when HTTP/HTTPS is used. Only when the
GXV3370 has the correct username and password configured, it can be authenticated by the firmware
server and the firmware file will be downloaded.
- Validate Certificate Chain:
This configures whether to validate the server certificate when downloading the firmware/config file. If
set to "Yes", the phone will download the firmware/config file only from the legitimate server.
Figure 23: Validate Certification Chain
GXV3370 supports uploading CA certificate to validate the server certificate and this setting is under
GXV3370 web UI→System Settings→Security Settings→Certificate Management.
