Re: UPS Connection at V5R4

["David Turnidge" <daveturnidge@xxxxxxxxx>]

I have been going through agony with UPSs myself. This is some of what I
learned:

If you plug in a cable to the UPS port on the iSeries, it reports a UPS
connected - EVEN IF THE OTHER END OF THE CABLE IS NOT CONNECTED TO A UPS.
This can be done while the system is running with no negative results. Take
out the cable and it reports that you are disconnected from the UPS.

OTOH, if you are plugged into another "server" (MSFT in our case) via USB
connecter, and then attach the iSeries cable AS WELL, the iSeries seems to
get a message that power has been lost, and will power off using whatever
method you have installed - in our case, 5 minutes. After it happened twice
to the same system we took the hint and didn't connect both system's sense
cables to the same UPS.

What we are planning to do is install the Ethernet management card,
disconnect the MSFT server and let the networking side control the system as
a result of feed back from the ethernet card. Then we can connect the sense
cable to the iSeries and all should be well.

Still learning,

Dave
