One MIPU board condition is alarm checking in local management desk but no any alarm information. Check MCU resource by RMCC, no resource belongs to this MIPU. In local management desk, we can see that this MIPU board indicator is green.
This board condition is “alarm” showing in local management desk.
Pulling out and plugging board do not have any effect. Change board slot and everything is normal, which means board is good. So it is motherboard interface behind slot that has problem. So we should change slot.
Data configuration problem causes interface connection problem and board problem, but local management desk has no prompt.
It does not means normal that no yellow or red board MCU in local management desk. We should check every board regularly.
