Problems with Best UPS 9910-140

[Philipp Rusch <Philipp.Rusch@xxxxxxxxxxxx>]

Hello all,
we have a 170-2290 and ext.box with CPM feature and a 9910-140 UPS.
Our UPS is connected with two 220 V cords.
Since a couple of weeks the UPS started clicking (like a relay which is falling 
off)
during normal operation, this is going on several times a minute or so.
No error logs, no shutdowns, just clicking.
I remembered some postings about this type of UPS, where you shouldn't use
the two downward plugs at the backplane, only the upper two of the four are
without that particular problem. Can anyone confirm this ?
Once I came in the morning, and the system was completely shutdown, no log
entrance in qsysopr log, none in sst. History log just stopped the night and I 
had
to manually put on the UPS again.
Do I have to expect growing problems with this beast, shall I call support  ?

Any help appreciated.

Regards from germany, Philipp Rusch
