Issue Description

There are a demonstration 8620MC system with 3 8020 terminal, after installing MCU and checking system settings every part of the board is OK. About 10 minutes later, we could no longer find IOMX board from the operation platform, and the diagnose system show IOMX board yellow color, but in the continuous presence subrack we can still find MPCP MPSP board. During the 10 minutes, we have not done any operation such as pulling out the IOMX board.

Alarm Information


Handling Process

1. Pull out IOMX board and reinsert it at the MCU on work status, then we still can’t find IOMX board from system diagnoses window.
2. Reboot the MCU cabinet, we can’t find IOMX board, switch to the 9th slot, we still can’t find IOMX board.
3. It is may be the software problem, as MPCP and MPSP board are still in gear, so we need try to demonstrate continuous presence.  After configure continuous presence, if video image stand still, the IOMX board can’t process the signal and effect continuous presence.
4. Replace a new IOMX board, system recognize the IOMX board, find IOMX board from the operation platform, continuous presence is in gear.

Root Cause

Poor contact between IOMX board and mother board or board fault
