Charging:
If the power supply modules of the DEV 5072 are working normally again, the
attached load is supplied by the power supply modules and the batteries are
charged, indicated by the downward pointing current arrow:
UPS Problems:
If the UPS functionality is activated (chapter 5.4.6.3.1) without installed
DEV 5101 or if there are problems with the communication to the BMC, no
sensible information is displayed in the panel. In these cases "System Status"
and "Latest Selftest Result" usually indicate "Unknown", numbers are repre-
sented either as "???" or as zero values, and instead of the battery capacity
indication with the percentage value a white bar labeled "Battery capacity
unknown" is shown:
Furthermore, the white bar labeled "Battery capacity unknown" is displayed if
the power system is put into operation initially or after a longer lasting power
down period, since the battery capacity indication is a longer lasting process
based on fully charged batteries.
