Firmware Upgrade
& Provisioning
& Provisioning
Enables GXW400x to download firmware or configuration file through either the TFTP or HTTP
server.
server.
Via TFTP Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank,
the GXW400x retrieves the new configuration file or new code image from the specified TFTP
server at boot time. After 5 attempts, the system will timeout and then it will start the boot
process using the existing code image in the Flash memory. If a TFTP server is configured and a
new code image is retrieved, the new downloaded image is saved into the Flash memory.
Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this
will damage the device. Depending on the network environment this process can take up to 15
or 20 minutes.

HTTPS Server
The URL for the HTTP server used for firmware upgrade and configuration via HTTP.
For example, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.1.8
“:6688” is the specific TCP port where the HTTP server is listening; it can be omitted if using
default port 80.
Note: If Auto Upgrade is set to No, GXW400x will only do HTTP download once at boot up.
