our NE80E had version VRP5.10-120002j version and we had 10G board on it. after a while the 10G boards got problem and they never registered again in the NE80E. we have 4 NE80E and on each of them we have 3 10G board.and on all of them we see this problem.
after 10G board fault the main board of NE80E alarm alarm LED was red and in display device the 10G LPU was not registered.
we upgrade the version to NE40E/NE80E VRP5.10-120031 and after that I install the damaged board that in previous VRP doesn't registered and I see that the damaged board registered successfully. and now 3 weeks past and the 10G boards are all safe.
we change so many 10G boards in NE80E's. they were work but after a while they were fault.
