Is the yellow light on because there was a message about battery in warning
status? Some other reason?
Our production E4A has a dual-input power supply that can keep the whole
box up on either power cord by itself. After experiencing a number of
UPS failures over the years, that shut us down while there wasn't a
thing wrong with the power coming out of the wall, when we got the E4A,
and determined that it could run on either power cord alone, we plugged
one into the wall, and one into the UPS.
When we have a power failure (naturally, we haven't had a UPS failure
since we started doing this!), or when we simulate a power failure to
test my power monitor program that sends out an email if it sees a
system operator message indicating power trouble, we get a yellow light
that doesn't go away until we clear it in SST.
