Re: Power Problem with a G3r
At this point I would have Avaya or a Business Partner take over the problem. If you look at the power distribution unit you will see a large white plug with a lot of wires in it that plugs into the unit. That cable represents power connections to several parts of the PBX. It is possible that the parts within the power distribution unit for the wires leading to carriers B and C (maybe even D and E if you had those carriers) might be bad and a new distribution unit is required. That unit is not field repairable.
The good news is that it does not take long to replace it, I have done it in less than ten minutes. And, yes, when it fails the failure is seldom a complete failure. It is also possible that the problem is one of the fuses in that power supply. Those can be replaced if it is one of them.
