Note: Supported syntax of "fwupdate.cfg" and "config.txt" may vary based on different firmware versions.
If you have existing configuration files, it is suggested to double check with Legrand Technical Support
for the correctness of these files prior to using this feature.
2. Configure your TFTP server properly. See
TFTP Requirements
(on page 443).
3. Copy ALL required configuration files into the TFTP root directory. If the tasks you will perform include
firmware upgrade, an appropriate firmware binary file is also required.
4. Properly configure your DHCP server so that it refers to the file "fwupdate.cfg" on the TFTP server for
your Legrand PDU.
Click one or more of the following links for detailed DHCP configuration instructions, based on your
operating system and the IP address type.

5. Make sure all of the desired Legrand PDUs use DHCP as the IP configuration method and have been
directly
connected to the network.
6. Re-boot these Legrand PDUs. The DHCP server will execute the commands in the "fwupdate.cfg" file on
the TFTP server to configure or upgrade those Legrand PDUs supporting DHCP in the same network.
DHCP will execute the "fwupdate.cfg" commands once for IPv4 and once for IPv6 respectively if both
IPv4 and IPv6 settings are configured properly in DHCP.
TFTP Requirements
To perform bulk configuration or firmware upgrade successfully, your TFTP server must meet the following
requirements:
The server is able to work with both IPv4 and IPv6.
In Linux, remove any IPv4 or IPv6 flags from
/etc/xinetd.d/tftp
.
Note: DHCP will execute the "fwupdate.cfg" commands once for IPv4 and once for IPv6 respectively if
both IPv4 and IPv6 settings are configured properly in DHCP.
All required configuration files are available in the TFTP root directory. See
Bulk
Configuration/Upgrade Procedure
(on page 442).
If you are going to upload any Legrand PDU diagnostic file or create a log file in the TFTP server, the first of
the following requirements is also required.
The TFTP server supports the write operation, including file creation and upload.
In Linux, provide the option "-c" for write support.
Required for uploading the diagnostic file only
- the timeout for file upload is set to one minute or
longer.
DHCP IPv4 Configuration in Windows
For those Legrand PDUs using IPv4 addresses, follow this procedure to configure your DHCP server. The
following illustration is based on Microsoft
®
Windows Server 2012 system.
Required Windows IPv4 settings in DHCP:
1. Add a new vendor class for Legrand PDU under IPv4.
a. Right-click the IPv4 node in DHCP to select Define Vendor Classes.
