You can perform a Secure Copy (SCP) command to update the PXE firmware. Same as any PXE firmware update, all user management operations are suspended and all login attempts fail during the firmware update. For details, see Firmware Update via Web Interface.
<firmware file> is the PXE firmware's filename. If the firmware file is not in the current directory, you must include the path in the filename.
<user name> is the 'admin' or any user profile with the Firmware Update permission.
<device ip> is the IP address of the PXE that you want to update.
When the system prompts you to enter the password for the specified user profile, type it and press Enter.
The system transmits the specified firmware file to the PXE, and shows the transmission speed and percentage.
When the transmission is complete, it shows the following message, indicating that the PXE starts to update its firmware now. Wait until the upgrade completes.
Starting firmware update. The connection will be closed now.
Tip: The PSCP works in a similar way to the SCP so the PSCP syntax for firmware update is the same as SCP. That is: pscp <firmware file> <user name>@<device ip>:/fwupdate
