Hi

On a yearly inspection on a S5 based system, I changed the Lithium battery (MB) in the power supply,

Before removal of the old lithium battery "MB low" was off and "RB low" was lit. :-)

When removing the old lithium battery both "MB low" and "RB low" was lit. :-)

After installing the new lithium battery both "MB low" and "RB low" turned off. :-O

There is no rechargable battery (RB) in the system, so why does this happen (i.e. why does the status lamp for the non existing rechargable battery follow the status of the lithium battery)?

Anyone knows about this behavior?

Info: We have a spare system identical the the above, where the "RB low", as expected, stayed lit after replacing the lithium battery.
