When thefan tray operates correctly, the OK LED is on, and the FAIL LED is off.If the OK LED is off or the FAIL LED is on, the fan tray has failed. To troubleshoot the fan tray:1. If both LEDs are off, verify that the power modules are operating correctly. For more information,see "Power supply system failure."2. Verify that the air intakes and exhaust vents of the chassis are not blocked. If they are blocked,clean them to keep good ventilation. If you install air filters, remove the air filters, clean them, andinstall them again.3. Verify that the fan tray is fully seated.
