1. Phenomenon description
The inspection department found a red light alarm on the H3C server during the on-site inspection, and checked the server status on the spot. After the on-site inspection, no failure was found. The out-of-band log information was collected and no alarm was found.
2. Solve the problem
After replacing the motherboard twice, I still gave an alarm after minimizing the start of the server. After unplugging a power supply, the alarm was cleared. Finally, it was because of the power supply. However, there was no alarm because it was a pitfall, and it took 3 days.
