I have the console cable plugged in and using powerchute to find out what is wrong with this unit. Last December it was functioning correctly, it was unplugged and sat in the bottom of the cabinet untouched for 10 months. We finished our migration and we are now using it to power around 5 servers. When I plugged the unit back in, the unit had a flat line beep and then said overload with no load on it. The overload reset switch does not stick out in the back, and if I unplug the battery and plug it back in, it will work as normal with a battery charge eventually going all the way up. With all of my servers plugged in and powered on the unit only shows about 3 out of 5 lights for the load. Eventually the same with happen, it will say overload and my servers will turn off. Sometimes the unit will display replace battery. As soon as I hold down the test button, it never passes and it will say overload, replace battery or AVR Trim.
I contacted APC support and they had me do a few steps and a brain dead test. The support was quite worthless, at one point the person didnt even read the past history of the ticket. Thier solution is to purchase a new unit.
Nothing has resolved this. I have posted pictures of my powerchute. Maybe someone can help me....
If the unit had been sitting for 10 months without the battery charge then it probably needs a new battery at the very least. If the battery was left connected for that duration then it should definitely be replaced. However, if the unit showed overload without any load, that generally isn't a good sign. If you just replace the battery I'm inclined to believe you still may encounter overload alarms.
The X180 at the end of your model number indicates that an APC network management card (ap9617) comes installed in the unit. I would configure that and [download the event and data logs|http://nam-en.apc.com/app/answers/detail/a_id/9321/kw/download%20event] as it may still have the old logs. The PowerChute logs begin only when the software is installed. These may help.
I forgot to get the log. I haven't gone onsite all week since Sat, and tonight I was trying to verify that my backups are executing and forgot to grab the log. I will try to grab tomorrow.
Today, when I tried to do test / power on, all the lights came on. Seemed normal for a few seconds, then shut off. The event log shows nothing other than communication est. disconnected. Battery connected, disconnected. Battery discharged etc...
