Eaton UPS 600 ASR USBS keeps awake my iMac

Hi!!

i bought last week an UPS Eaton Ellipse 600VA USBS ASR.

I plugged to my mac and everything is alright (i can see the icon showing the charge), but when i set 'sleep' in my mac, just "sleeps" around 30 seconds. Then, wakes up automatically.

This just happen when the usb between UPS and iMac is plugged. If i unplug it, everything's ok and my imac sleeps perfectly.

I did not install any driver (as far as i know, is no necessary). I´ve tried with software such like PleaseSleep but the problem continues.... What can i do?

Thanks for advance!!!

iMac 24'' Intel - 2,66Ghz, Mac OS X (10.6.2)

Does the UPS have enough juice to power the iMac? In other words, if you pull the plug on the UPS how long does the Mac run?

It is quite possible that the UPS is overloaded, especially if anything besides the iMac is plugged in.

Is that UPS Mac compatible?

Hi, only the iMac is plugged in the UPS, no other device is connected.

The UPS is 600VA (400WA), enough to supply the computer. I´ve tested the UPS power (disconnecting from general power) and gives power to the mac perfectly.

In the specifications, Mac OSX 10.6.2 is full compatible. My iMac recognizes the model (ELLIPSE), shows the UPS tab in the power management and everything looks alright.

No overload light is shown in the UPS.

Thanks!!!

I can't seem to find anything on the Eaton website indicating that the unit is Snow Leopard compatible–are you able to supply a link?

I do see where it says Mac OSX compatible, but unfortunately that does not specifically mean Snow Leopard. It does sound like it is the UPS waking up the Mac.

I also don't see any Mac drivers or software posted on their site. Have you been able to find updated versions?

You´re right, on Eaton website is not shown, but in the instructions inside (also you can download it), they confirm compatibility and shows even some known bugs for 10.6.2 (such as does not restart after a shutdown), but does not tell nothing about this.

Well that particular bug (and others that they mention) would indicate that the unit is not actually Snow Leopard compatible but that it simply kind of works.

The bug that they do mention would certainly indicate that their UPS is not capable of communicating properly with SL. My guess is that if you email them and they respond they will indicate that this is a "bug" as well.

If you do contact them, ask when you can expect updated (read Snow Leopard compatible) drivers and software.

If it isn't too late you may want to return this unit and get something that is known to be compatible.
