Issue:

The Firmware Upgrade Wizard (FUW) is the most universal and preferred method of updating.

If a previous version of the Firmware Upgrade Wizard or Firmware Images are installed, delete the old version and download the latest revision.

Links to download all necessary files can be found at the end of this document.

IMPORTANT: Certain UPS models do not support firmware update using a USB connection. To update the firmware of these UPS units using the Firmware Upgrade Wizard, a local connection via serial cable must be used. The serial cable supplied with the UPS must be used. Refer to the table below to verify USB support.

• Follow the link the video guide on How to locate the UPS ID for APC Smart-UPS
• The same models of UPS may have different UPS IDs depending on when they were produced.

• If the UPS ID is not listed in the below table, it does not have an update available.
• The Firmware Upgrade Wizard will select the correct version for the unit you are updating.

Note: it is not recommended to perform a firmware downgrade to a lower firmware version than the current UPS firmware.
