Hi All

We have a very simple set up, looking for a very simple (reliable) solution:

Setup:
One Dell box with redundant power supplies running Windows 2003, plugged into two separate APC SmartUPS 1500 units (USB, no smart cards) on two separate circuits.

Solution required:
IF (UPS1 = Low) AND (UPS2 = Low) THEN: Shutdown gracefully ELSE: DO NOTHING!!

APCUPSD only allowes for one instance (and therefore one UPS) in a windows environment.
PowerChute can't do this without using APC Smart Cards which means utilizing our switch, but the switch does not have redundant power supplies, so it will only live for as long as one of the two UPS units. And no, i don't have the budget to buy two smart cards pluse a switch with redundancy ;)

Thanks
