1. Problem phenomenon

Customers reported that every time they tried to start the 2u industrial pc, the indicator light on the chassis did not light up. At the same time, although the fan started, it soon stopped and the whole machine fell into silence.

1. Hardware check: Faced with this problem, we quickly conducted a hardware check and suspected that the power supply or the components on the motherboard may have failed, resulting in the inability of the current to flow normally.

2. System log analysis: Because the chassis did not light up, we could not enter the system, so we could not perform detailed analysis through the system log. We will focus on the hardware and try to solve this mystery.

2. Possible causes

1. Power supply problem: We first checked whether the power supply is normal and whether the power line is damaged, as this may cause the chassis to fail to light up.

2. Cooling fan problem: The fan stops after starting, which may be due to a fault in the cooling fan itself or the protection mechanism caused by overheating.

3. Solution

- Detected a short circuit on the light board: After careful investigation, we found that the problem was with the light board on the chassis, where the switch button was short-circuited.

Possible causes of light board short circuit:

1. Aging of the light board: Long-term use may cause the light board to age, increasing the risk of failure.

2. Circuit design defects: Design defects may make the light board more susceptible to current fluctuations.

Operation steps for replacing the light board:

1. Back up machine data: Before any hardware replacement, we recommend that users first back up important machine data to avoid data loss due to replacing the light board.

2. Disassemble the old light board: Provide detailed disassembly steps to ensure that users will not encounter operational problems when replacing the light board.

3. Install the new light board: Instruct users on how to correctly install the new light board, including precautions for anti-static and correct circuit connection.

4. Problem Solving Effect

1. Start the chassis: After replacing the light board, the user restarted the chassis and found that the indicator light could light up normally and the fan could continue to run, verifying that the problem was effectively solved.

2. User Feedback: Solicit user feedback to confirm whether there are other potential problems and their experience during use. The user expressed satisfaction with the solution and did not find other abnormalities.
