Firmware Upgrade via USB
Firmware files are available on the Legrand PDU section of Raritan website's
Support page
Note that if the firmware file used for firmware upgrade is the same as the firmware version running on the
Legrand PDU, no firmware upgrade will be performed unless you have set the
force_update
option to true in
the "fwupdate.cfg" file. See
fwupdate.cfg
To use a USB drive to upgrade the Legrand PDU:
1. Copy the configuration file "fwupdate.cfg" and an appropriate firmware file to the root directory of the
USB drive.
2. Reference the firmware file in the
image
option of the "fwupdate.cfg" file.
3. Plug the USB drive into the USB-A port on the Legrand PDU.
4. The Legrand PDU performs the firmware upgrade.
The front panel display shows the firmware upgrade progress.
Tip: You can remove the USB drive and plug it into another Legrand PDU for firmware upgrade when the
firmware upgrade message displays.
5. It may take one to five minutes to complete the firmware upgrade, depending on your product.
6. When the firmware upgrade finishes, the front panel display indicates the firmware upgrade result.
