Such a problem is likely caused because of the poor contact betweenthe PSU and the backplane due to a badly seated PSU. In this case, switch off thepower supply, loosen the captive screws on the PSU, push the PSU into thechassis a little bit, tighten the captive screws, and switch on the power supply tocheck that the normal state is resumed.z The Input LED (green) and Output LED (green) are OFF. In this case, check thatthe power cords are connected correctly, the power cords are in good condition,and the power switch has been put in the ON position.z The Fail LED (red) is ON. In this case, check that the correct power voltage is inuse (i.e., 90 to 264 VAC, 50-60 Hz for AC PSU, and -36 to -72 VDC for DC PSU).z The Fail LED (red) is ON. In this case, check that the air filter protecting the fantray is clean. Excessive dust accumulated on the air filter will block the fan trayfrom free ventilation and even lead to power supply failure.Note:If you cannot solve the problem after going through the above checking steps, contactH3C technical support.5.1.3 Troubleshooting the Fan Tray(s)The S9500 series provide two LEDs on the fan tray. You can read them and knowwhether the fans are normal.
