Hi Daryl
What type of unit is the NMC installed in? Many different systems require their own particular firmware revision. SY (what was originally loaded) is the firmware for the Symmetra LX/RM, SUMX (what is loaded now) is the firmware for single phase SmartUPS and Matrix units, etc.

Hi,
If your UPS is a Smart-UPS you have installed the wrong firmware. You need to install SFSUMX672.
