Um, well.... The beginning of the year, we had a utility shutdown for
repairs, so we shut all our servers down, and the UPSs as well. Brought
them back up after the long weekend... and it took over a month for the
red light to come back. Watch out that the one you swapped doesn't come
back in a few weeks.
