That’s all I found without physical manual…
These SRCs start with 1.
SRC What it means
1xxx xxxx Check for a specific 1xxx SRC. If you do not see your SRC, a System Power Control Network (SPCN) failure may have been detected.
My Problem Analysis, Repair and Parts manual doesn’t show that exact SRC code (I have a 9406-720). But, the range of the code (2541) (in my manual) is inbetween the range of UPS (internal batteries) (2413 – UPS interface failure) or the power supply (2551 – power supply fault).
