Unsure of what firmware to download for Smart UPS SMC1500IC

[Astral85]

There are six firmware files available to download on the SMC 1500IC product page and I'm unsure which one to download. Could anyone explain what to look for?

This APC Resource link will provide you all the insight you need to know and follow:

More specifically, this resource link will provide you the link to the FUW (Firmware Upgrade Wizard). The Windows based FUW application contains all the needed files, notes, and EXE application. Once the FUW Application is launched it will present you with the ONLY specific firmware that applies to your hardware.

The FUW includes ALL the UPS firmware for other APC UPS Models hence why you see multiple files available for download. 

NOTE: The UPS Firmware should only be done to resolve bugs, security, or to obtain a feature enhancement. The firmware upgrade process should be guided and done live over the phone with an APC Technical Support personal when (In Warranty). Should there be a problem / failure they may be able to assist in a break fix or facilitate an RMA.

If the hardware is NOT in warranty you have a better than 50% chance of bricking the unit during the firmware upgrade process if all requirements are not met. 

Good luck and let me know how it all turns out and if this answered your query please do mark this as a solution.
