Dealing with an “Hp Proliant Ml570 G2 Fan Failure Detected” message can be frustrating, especially when your server’s stability is at stake. This error indicates a problem with the cooling system, which, if left unaddressed, can lead to overheating and potentially damage critical components. We’ll explore the causes, troubleshooting steps, and solutions for this common issue.
Understanding the HP ProLiant ML570 G2 Cooling System
The HP ProLiant ML570 G2 relies on a robust cooling system to maintain optimal operating temperatures. Multiple fans work in concert to dissipate heat generated by the processors, memory modules, and other internal components. The server’s Integrated Lights-Out (iLO) management controller monitors these fans and triggers the “fan failure detected” message when a problem arises. Understanding how this system works is crucial for effective troubleshooting. The fans themselves are hot-swappable, meaning they can be replaced without powering down the server, minimizing downtime.

Common Causes of HP ProLiant ML570 G2 Fan Failure
Several factors can contribute to fan failures in the ML570 G2. Dust accumulation is a frequent culprit, obstructing airflow and hindering fan performance. Over time, the fans themselves can wear out, leading to reduced speed or complete failure. Loose connections or faulty cabling can also disrupt the communication between the fans and the iLO controller. Finally, a malfunctioning iLO controller itself can sometimes incorrectly report a fan failure.
Troubleshooting HP ProLiant ML570 G2 Fan Failure Detected Errors
When you encounter a “fan failure detected” message, it’s essential to take a systematic approach to diagnose the problem. Start by checking the iLO event logs for specific error codes related to the fans. Physically inspect the fans for any signs of damage, obstruction, or unusual noise. Ensure all fan cables are securely connected. If possible, test the fans individually to isolate the faulty component.

Solutions for HP ProLiant ML570 G2 Fan Issues
Once you’ve identified the cause of the fan failure, you can implement the appropriate solution. Cleaning dust buildup from the fans and server interior is often a simple yet effective fix. Replacing a faulty fan is straightforward thanks to the hot-swappable design. If a cable or connection is the issue, reseating or replacing the cable should resolve the problem. In rare cases, a faulty iLO controller may require replacement.
What if the iLO is reporting a false positive?
Sometimes, the iLO can incorrectly report a fan failure. Updating the iLO firmware to the latest version can often resolve such issues. However, if the problem persists, further investigation into the iLO controller itself may be necessary.
How to prevent future fan failures?
Regular maintenance, including cleaning the server and fans, can significantly extend the lifespan of your cooling system. Monitoring fan speeds and temperatures through iLO can help detect potential issues early on. Using high-quality replacement fans is also crucial for long-term reliability.
