Try erasing the neighbor relationship and re-create it. delete the cells and re-create them then you can assume it is a hardware/software problem in one of the boards. this is an advanced troubleshooting, so good luck if you reach that stage 🙂 regards pix 26th July 2010 at 12:08 #63712 julianoGuest you can see two parameter: NY1 and timer T3105 16th March 2011 at 12:56 #63713 CoreGuest How to know if the failures on the same cell or not from Core side?!
