I have 2 of these things: APC SmartUPS SC1500 (220v). My Proliant G5 DL380 PSUs seem to really hate them. This is what happens when UPS switches to battery (PSU2 is plugged into the SC1500):
iLo IML log:
</>hpiLO-> show system1/log1/record2 severity=NonCritical date=06/06/2013 time=07:32 description=System Power Supply: General Failure (Power Supply 2) </>hpiLO-> show system1/log1/record3 severity=NonCritical date=06/06/2013 time=07:32 description=System Power Supplies Not Redundant
Every single time the SC1500 goes on battery, PSU goes dark then quickly back up again. If i plug PSU1 into the SC1500, same result.
I did some reading (really nice stuff BTW), http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02492972/c02492972.pdf http://community.spiceworks.com/topic/93413-hp-ml350-g6-vs-apc-1500-ups
i have older SmartUPSes from APC (SU1400RMI2U) which either put out a better sine or have a faster transfer time because the PSUs in the DL380 acts very natural when they switch over to battery.
Aren't all SmartUPSes supposed to put out a clean sine?
I'm going to bring my Tektronix from home and check just how much of a sine is the SC1500's output really, but i was just wondering if this is a common problem with the SC1500 or i've been delivered some duds.
