The HT–496can be configured via Web Interface as well as via Configuration File through TFTP or HTTP.
“Config Server Path” is the TFTP or HTTP 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 same or different from
the “Firmware Server Path”.
A configuration parameter is associated with each particular field in the web configuration page. A
parameter consists of a Capital letter
P
and 2 to 3 (Could be extended to 4 in the future) digit numeric
numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a
detailed parameter list, please refer to the corresponding configuration template of the firmware.
Once the HT–496 boots up (or re-booted), it will request a configuration file named “cfgxxxxxxxxxxxx”,
where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The configuration file
name should be in lower cases.

Firmware Prefix and Postfix allows the device to download the firmware name with the matching Prefix
and Postfix. This makes it possible to store ALL firmware with different versions in a single directory.
Similarly, Config File Prefix and Postfix allows the device to download the configuration file with the
matching Prefix and Postfix, allowing multiple configuration files for the same device to be stored in one
directory.
In addition, when the field “
Check New Firmware only when F/W pre/suffix changes
” is set to “Yes”, the
device will only issue a firmware upgrade request if there are changes in the firmware Prefix or Postfix.
This feature is supported for all firmware starting with version 1.0.3.18 for HT–496.

When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in
minutes, default and minimum is 60 minutes) to have the devices periodically check with either Firmware
Server or Config Server, whenever they are defined. This allows the device periodically check if there are
any new changes need to be taken on a scheduled time. By defining different intervals in P193 for
different devices, Server Provider can spread the Firmware or Configuration File download in minutes to
reduce the Firmware or Provisioning Server load at any given time.
