Issue:

Because the Firmware Upgrade Wizard is the most universal and preferred method of updating, we recommend using the APC Firmware Upgrade Wizard whenever possible. The APC Firmware Upgrade Wizard guides you through the update process and provides a consistent update experience. The Firmware Upgrade Wizard is available in FA279197. Not all models are supported by the Firmware upgrade Wizard. Instructions are being provided here for users that are unable use the Firmware Upgrade Wizard or prefer to update their Smart-UPS Firmware using the web interface of an APC Network Management Card (NMC). For those who wish to update their Smart-UPS Firmware using the NMC's command line interface (CLI), see FAQ000242942 .

Product Line:

Smart-UPS models with the prefixes SCL, SMC, SMT, SMTL, SMX, SRT, SRTL, SRYL, XP, and XU with a SmartSlot or embedded NMC.


Environment:

• Supported UPS model listed above
• Supported Web browsers: Microsoft® Internet Explorer® (IE) 8.x or higher, with compatibility view turned on; the latest release of Microsoft® Edge®; the latest releases of Mozilla® Firefox® or Google® Chrome®
• UPS Network Management Card 2 (AP9630, AP9630CH, AP9631, AP9631CH, or embedded NMC2) with SUMX application firmware v6.4.0 or higher
• UPS Network Management Card 3 (AP9640, AP9641, AP9643, or embedded NMC3) with SU application firmware 1.0 or higher
• Correct firmware file for the particular UPS available in the table below

Resolution:

Follow the steps below to determine your current NMC firmware revision, select the proper UPS firmware file, and update the UPS firmware via the Network Management Card web interface.

NOTE: When performing the UPS firmware update using the NMC web interface, while connected to the web interface over Wi-Fi, a different network, or VPN, a file transfer timeout may occur if an HTTPS connection is used. Refer to FAQ000234317 for alternative methods to update the UPS firmware using the NMC.

Step 1 - Check if you have a Network Management Card 2 running Smart-UPS / Matrix Application, or a Network Management Card 3 running Smart-UPS Application, and ensure there are no active alarms reported.

Network Management Card 2 running Smart-UPS / Matrix Application:


Network Management Card 3 running Smart-UPS Application:


Step 2 - If using Network Management Card 3, go to Step 3.
If using Network Management Card 2: Verify the firmware revision of your Network Management Card. From the NMC web interface choose “About”, then “Network”. The firmware must be v.6.4.0 or higher, but we recommend you always run the latest available NMC firmware. To update the firmware of your Network Management Card, refer to FA156047 .



Step 3 – Identify the correct UPS Firmware file.
Note: Always update to the latest Network Management Card firmware before updating the UPS firmware.  See .  See FA156047, FAQ000261841

• From the NMC web interface choose “About”, then “UPS”:
• Identify the "ID" number to select the proper firmware file for your UPS.
  • For example, for a UPS with ID 1025 the proper filename will be SRT1025UPS_15-0.enc

• Download the appropriate firmware file available in the table below.

The "ID" is a unique identifier for the hardware platform of your UPS. You need to use the "ID" number to make sure to select the correct firmware file. A particular UPS model may have different "ID" numbers depending on when it was manufactured, or its current firmware version. Always check the "ID" number of the UPS before starting the update, and ensure you use a firmware file with the compatible ID. If the incorrect file is used, the update will be refused, and will need to be restarted using the correct firmware file.

Use the table below to determine the correct firmware file for your UPS.

Notes:

1. *For SRT UPS models with ID of 1001, 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 to UPS 02.9 is completed, perform the firmware update again using SRT1013UPS_15-0.enc
2. ** For SRTL UPS models with ID 1226 & 1227, always perform a Logic Reset or "Brain Dead" before initiating the firmware update. Refer to FAQ000269051 for more information.
3. It is not recommended to perform a firmware downgrade to a lower firmware version.
4. In rare situations, the UPS firmware update may not install automatically after the firmware file was transferred to the UPS. Refer to FAQ000258690 to complete the UPS firmware update.
5. For more information about enabling or disabling firmware updates via the NMC for the UPS models that support this feature, refer to FAQ00024438.
6. Once firmware updates via the NMC have been disabled, attempts to update the UPS firmware using the NMC will be refused:
7. For SRYL (Smart UPS Modular Ultra), if upgrading from 13.2 or greater you may put the UPS into Manual Bypass. See Set the UPS to Manual Bypass Mode section in the Smart UPS Modular Ultra Manual.

Step 4 – The majority of UPS models support firmware update with output on. Refer to the above table, and if you have a UPS that supports firmware update with output on, go to Step 5.

NOTE: For UPS devices that require the UPS output to be off before initiating the update, ensure that network access is not dependent on the UPS for power, when updating via the Network Management Card.

If network access is dependent on the UPS for power, refer to FA279197 for instructions on updating the UPS firmware using the Firmware Upgrade Wizard.

If network access is not dependent on the UPS for power, ensure the attached load is correctly shut down before proceeding with turning off the UPS output.



To turn off the UPS output, from the NMC web interface choose “Control”, then “UPS”:





Step 5 – Navigate to the "Configuration" Menu, select "Firmware Update", then use the "Choose File" button to browse for the correct firmware file downloaded and identified in Step 3.
Once the correct Firmware file has been selected, click the “Update UPS” button to apply the update.



The below window will open after selecting “Update UPS”



Notes:

1. The update may take several minutes. When this window closes, the update is complete. Verify that the new UPS Firmware version is shown using the same procedure shown in Step 3.

• Note: For Smart UPS Modular Ultra, the update may take more than 20 minutes to complete

1. If the update does not complete, or if any errors are displayed, ensure that the conditions in Step 1 are met. Try updating the UPS firmware with the UPS output turned off. If no alarms are shown, try updating the UPS firmware using the Firmware Upgrade Wizard, which can be found in FA279197.

Step 6 - If the UPS output was turned off in Step 4, the UPS output should now be turned back on.
From the NMC web interface choose “Control”, then “UPS”
“Skip outlet on delays” may be selected if required to restore power immediately.



The attached load can now be turned on.
