Re: Problems with Best UPS 9910-140

After a user complained that his AS/400 seemed to be haunted, IBM
and uninterruptible power supply (UPS) manufacturer Best Power
discovered that under certain operating and environmental
conditions, the continuous powered mainstore (CPM) UPS units that
Best Power manufactures for IBM Global Services to resell may cause
AS/400 servers to shut down without corresponding source code. The
CPM units at risk are 9910-080 and 9910-140 UPS Products with serial
numbers EC 2P OD 47286 2.07 code, EC 2P OD 47287 2.08 code, EC 2P OD 47275
4.01 code. EC numbers are located on the rear of the UPS.

IBM and Best Power issued a software enhancement to ward off the
remote -- but frightful -- possibility. The free enhancement as well
as technical support is available at
http://www.bestpower.com/service_support/ibmalert/. Customers can
also call Best Power at 1-800-356-5737.

> 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.
