I rencently won a APC POWERSTACK PS450I on Ebay for £12.50 inc a 90 day warrenty.

I have recieved the UPS through the other day, and also got some power cables through to be able to test it finally.

If I plug the UPS in to a power outlet and turn the UPS on a green light flashes, I hear a click and an orange light flashes as well next to a picture of a batter with a line through it. After a couple of seconds the orange light goes off, and then the green light is on constantly next to the picture that looks like it is to do with power surges. I have left the unit like that for over 24hrs and then pulled out the power cable and the orange light is on constant and bleeps every now and again. Which is all ok

When I run something from UPS (e.g. Cisco Switch), unless I plug it in / power up after the UPS has done its power up cycle (or whatever its called) a red light appears next to the picture with a battery with a cross through it and it bleeps constantly. If I turn on the UPS and then the switch, and remove the power lead from the UPS the red lights comes on and starts bleeping and instantly the switch goes off i.e. no delay.

I have ordered a DB9 cable and downloaded Parachute to see if it gives me any more information when I can test it. Although I haven’t had any hardware dealing with UPS’s before I would say that it is an issue with the battery, as it seams to be whenever its need to switch to the battery it has any problems.



Any ideas guys???
