Re: using UPS on a 720

You don't/can't connect via USB. The Power7/Power8 servers have 2 serial
ports ( S1 and S2 on the back, but you can't directly use those ports.
Power Systems ( AS/400 and iSeries too ) use an OPEN/CLOSE circuit
connection to signal the system the status of the UPS. Some APC units
support a card to provide that type of signalling. On the Server side there
is special cable that when used tells the server to use the port as an UPS
Port.

Where do I connect the USB cable from a UPS to a power7 720? I want to
receive a message from the UPS when the power fails.

I have the 720 working on the UPS. The UPS is rated at 810W and the system
powered up thru the UPS. Then it held when I pulled the power cord from the
wall. Should be no problem, right?

( the UPS is made by CyberPower. purchased at Costco. $90. I had tried an
APC UPS rated at 550W. Did not hold when I powered up the 720. )

thanks,
