7.1 Firmware Server Setup
No special server is necessary for the firmware update. You can use an HTTP, HTTPS, FTP, or TFTP
server as the firmware server by simply setting its URL.
Note
• This feature is available only in IPv4 mode.
• A firmware update takes about 4 minutes.
• The unit will restart after the firmware update is complete.
• The unit cannot be used while the firmware is being updated.
• It is recommended to select a time for updating in which the unit will not be used. (For details about
the timing of updating configuration files, see 2.2.4 Downloading Configuration Files.)
7.2 Firmware Update Settings
Firmware updates are provided by the manufacturer when necessary.
The firmware update will be executed by setting the corresponding parameters using configuration file
programming (→ see 5.3.6 Firmware Update Settings) or Web user interface programming (→ see
4.7.2 Firmware Maintenance). The following shows the parameters and the setting procedures:
Firmware Update Enable/Disable
• In a configuration file, add the line, FIRM_UPGRADE_ENABLE="Y".
• In the Web user interface, click the [Maintenance] tab, click [Firmware Maintenance], and then select
[Yes] for [Enable Firmware Update].
Firmware Version Number
• In a configuration file, specify the new version number in "FIRM_VERSION".
Firmware Server URL
• In a configuration file, specify the URL in "FIRM_FILE_PATH".
• In the Web user interface, click the [Maintenance] tab, click [Firmware Maintenance], and then enter
the URL in [Firmware File URL].
Configuration Parameter Example
By setting the parameters as shown in the following example, the unit will automatically download the
firmware file from the specified URL, "http://firm.example.com/firm/01.050.fw", and perform the update
operation if the currently used firmware version is older than 01.050.
Example
FIRM_UPGRADE_ENABLE="Y"
FIRM_VERSION="01.050"
FIRM_FILE_PATH="http://firm.example.com/firm/01.050.fw"
7.3 Executing Firmware Update
After configuring the firmware update settings in the configuration file, the firmware will be updated when the
configuration file is downloaded. The firmware update procedure is detailed below.
