Back-UPS Pro 500 BG500 120 Vac36
Steps to update the UPS firmware:
1. If a UPS firmware update file is not already loaded onto the UPS, then FTP into the UPS and put the update
file into the upsfw directory. The UPS may abort the FTP firmware transfer if it detects that the update file
is corrupted.
Here's an example of loading an update file using the DOS FTP command:
2. Check the firmware update page to see that the update file is loaded onto the UPS. Below the file path, you
may see:
• Incompatible with this UPS
Indicates that update file will not work with this UPS because it is designed for a different one.
• Unknown format
Indicates that the update file does not appear to be a valid UPS firmware update file. The file could
indeed be invalid, or in a format that the UPS does not yet recognize.
3. If the update file exists on the USP, then the UPS will display the update version. This will be listed as
unknown if the UPS does not recognize the format of the update file. Otherwise this lists the version each
UPS component assumes after the update. Greyed out components are not part of this update file.
4. Press the Update UPS button to start the update process.
When the update finishes, check the status under Last Update Result or in the event log.
