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.

Product Line:

Smart-UPS models with the prefixes CSH, SCL, SMC, SMT, SMTL, SMX, SRT, SRTL, XP, and XU

Note: The Firmware Upgrade Wizard does not support the below Smart-UPS devices:

• Models with the prefixes SRC, SU, SUA, SUM, SURT, SURTA, SURTD
• SMX750, SMX1000, and SMX1500 with ID 11 and firmware UPS 02.x or lower. These units are 120V devices built prior to date code 1037. The date code is the first 4 numbers in your serial number. For example, serial number AS1036123456 would not be supported.
• Devices not supported in the current release: SMT750RMJ1U, SMT2200, SMC2200XLI-BR

Environment:

The system requirements for the Firmware Upgrade Wizard are as follows:
Operating systems: 64-bit Windows 7, 8.1 Pro, Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, Windows Server 2022

To find the current UPS Firmware version via the UPS LCD display:
The Firmware Upgrade Wizard will detect the current version.
Alternately, from the main menu of the UPS LCD screen, select "About" and scroll down to "UPS Firmware".

To find the current UPS Firmware version via Firmware Upgrade Wizard:
Run the Firmware Upgrade Wizard and it will identify the current firmware version before performing the update.

To find the current UPS ID:
Every Smart-UPS has a unique UPS ID. This can be found in the "About" menu on the UPS LCD screen, or in the NMC web interface.

• 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.
• The final firmware version will be determined by the UPS ID and not the Model Number of the UPS.
• 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.

Notes:

1. *For SRT UPS models with ID1001, the UPS firmware must be updated twice. First update the UPS firmware using SRT1001UPS_02-9.enc. This will change the UPS ID to 1013. Once the update is completed, perform the firmware update again using SRT1013UPS_15-0.enc.
2. As shown in the above table, in some cases, there are two or more firmware images listed for the same UPS ID. The selection of the appropriate file is taken care by a new feature in Firmware Upgrade Wizard, that shows only the relevant and latest firmware for the connected UPS.
3. If update via USB is not supported, or if updating via serial cable, the serial cable that is included with the UPS must be used.
4. If updating a UPS unit due to a "Needs Firmware Update" or "Battery Sys Error 0800" alarm, the external battery packs MUST be connected when performing the update. If more external battery packs are connected at a later date and the issue returns, the firmware update must be performed again with all battery packs connected. Updating an SRT UPS unit may take up to 20 minutes to complete. The more external battery packs are connected, the longer the update may take.
5. In rare situations, the UPS firmware update may not install automatically after the firmware file was transferred to the UPS. Refer to FAQ000258266 to complete the firmware update.

DO NOT DISCONNECT THE UPS COMMUNICATION CABLE, REBOOT THE COMPUTER, OR ATTEMPT TO TURN OFF THE UPS DURING THE FIRMWARE UPDATE.
