How do I update the firmware of my SRT series Smart-UPS using the Firmware Upgrade Wizard?

Published date: 14 January 2020

Issue: 

There are two methods to update the firmware of the UPS:
  • Locally via a Serial or USB connection using the Firmware Upgrade Wizard application
  • Remotely via the Network Management Card
  • The Firmware Upgrade Wizard is the most reliable and preferred method of upgrading.
 
If you have a previous version of the Firmware Upgrade Wizard or Firmware Images, delete the old version and download the latest revision.
If you need to upgrade an SMT/SMC/SMX unit, or need to upgrade via the Network Management Card, refer to Kbase #FA164737

 SRT 1.0/1.5KVA 120V only 1019  UPS 07.9
 SRT 2.2/3KVA 1025  UPS 07.9

Note: Upgrading SRT 5/6KVA units from version 2.x requires updating to version 2.9, and then it is recommended to update to the latest version.
This will require that you run through the firmware upgrade process twice. The first upgrade will bring you to 2.9 and the second upgrade will bring you to 5.0.

Note: If you are upgrading an SRT unit due to a "Needs Firmware Update" or "Battery Sys Error 0800" message, you MUST have your external battery packs connected when you perform the upgrade. If you connect more external packs at a later date and the issue returns, you will need to run the update again with all battery packs connected. Upgrading an SRT unit may take up to 20 minutes to complete.
DO NOT REBOOT YOU COMPUTER OR ATTEMPT TO TURN OFF THE UPS DURING THIS TIME.
The more external battery packs are connected, the longer the upgrade will take.

Note: You must use the serial cable that is included with your UPS. If upgrading via USB, it is recommended that you use the included USB cable.
 

Note: A firmware image for the XP1K9NN42RCC is not included with the Firmware Upgrade Wizard.
You can download the image HERE.
When you get to the “Browse” screen of the Firmware Upgrade Wizard, browse to the image you downloaded ("PMU1016UPS_02-3.enc"), and continue from there.

Resolution:

Customers wanting to upgrade their UPS firmware should download  "Firmware Upgrade Wizard v4.2.0" as well as the "Firmware Upgrade Wizard Manual"  files. 
 
The "Firmware Upgrade Wizard v4.2.0" file contains the self-extracting executable file, as well as all necessary UPS firmware images. Read the "Firmware Upgrade Wizard Manual" before beginning the process.
The users manual provides a complete step by step walk through of the process including all necessary screenshots. The complete process will take 5-20 minutes and will require that you power down any load attached to the UPS

Note: A firmware upgrade error screen may appear at the end of the upgrade. This is a known issue with Firmware Upgrade Wizard v4.2 that will be addressed in the next revision. The screen can be ignored, the firmware successfully upgraded.
  • To confirm your firmware version:
Run the Firmware Upgrade Wizard and it will identify the current firmware version before performing the update.
Or, turn on the UPS and access the LCD screen and navigate to About > UPS Firmware to verify the firmware version.
 
If you run into any issues during the process or have any additional questions, please contact APC Tech Support.
