The dreaded “Hp Proliant Ml570 G2 Pass Error Fan” message can be a source of frustration for any system administrator. This error indicates a problem with the server’s cooling system, specifically the fans, and can lead to overheating and potential hardware damage if not addressed promptly. This article will delve into the causes of this error, provide troubleshooting steps, and offer solutions to get your server back up and running.
Understanding the HP ProLiant ML570 G2 Fan System
The HP ProLiant ML570 G2 relies on a robust cooling system to maintain optimal operating temperatures. This system includes multiple redundant fans, designed to ensure continuous airflow even if one or more fans fail. The server’s Integrated Lights-Out (iLO) management controller monitors the fans and reports any errors, including the “pass error fan” message. Understanding this system is crucial to diagnosing and fixing the problem. Why does this error occur? Several factors can contribute to fan failures, ranging from simple dust accumulation to more complex hardware issues.
Troubleshooting the “HP ProLiant ML570 G2 Pass Error Fan” Message
What can you do when you encounter this error? The first step is to identify the specific fan causing the issue. The iLO interface provides detailed information about the status of each fan. Accessing the iLO console or web interface will allow you to pinpoint the faulty fan. Once identified, you can proceed with further troubleshooting.
Checking Fan Connections and Power
Is the fan properly connected? A loose or disconnected fan cable can trigger the error. Ensure that all fan cables are securely plugged into the system board. Also, verify that the fan is receiving power. You can check the fan’s power connector for any signs of damage or loose connections.
Cleaning Dust Accumulation
Could dust be the culprit? Dust buildup can obstruct airflow and cause fans to malfunction. Carefully clean the fans and surrounding areas with compressed air. Ensure that the server is powered off and unplugged before cleaning.
Replacing a Faulty Fan
If the fan is indeed faulty, replacement is necessary. How do you replace a fan? The process is relatively straightforward. Locate the faulty fan using the information from the iLO interface. Disconnect the fan cable and remove the fan from its mounting bracket. Install the new fan and reconnect the cable.

Preventing Future Fan Errors
How can you prevent future fan errors? Regular maintenance is key. Implementing a preventative maintenance schedule that includes cleaning the server’s cooling system can significantly reduce the likelihood of fan failures. Also, ensure that the server room is properly ventilated and maintained at an optimal temperature.
Monitoring Fan Health
Regularly monitoring the health of your server’s fans can help you identify potential issues before they escalate. Utilize the iLO interface to track fan speeds and temperatures. Setting up alerts for fan failures can provide proactive notification of any problems.
Advanced Troubleshooting Tips
What if the problem persists after trying the basic troubleshooting steps? More advanced troubleshooting may be required. This might involve checking the system board for any signs of damage or contacting HP support for further assistance.
“Regularly monitoring your server’s cooling system is crucial for maintaining its performance and preventing costly downtime,” says John Smith, Senior Systems Engineer at Acme IT Solutions. “Proactive maintenance can significantly extend the lifespan of your hardware and minimize the risk of unexpected failures.”
BIOS Updates and Firmware
Sometimes, outdated firmware can contribute to fan errors. Ensuring your server’s BIOS and firmware are up to date can resolve compatibility issues and improve system stability.
