Description: The fans in a fan tray are not functioning normally.
Follow these guidelines to troubleshoot the fans:
Check the fan LEDs and alarm LEDs on the craft interface.
If the major alarm LED on the craft interface lights, use the CLI to get information about
the source of an alarm condition:
If the CLI output lists only one fan failure, and the other fans are functioning normally,
the fan is most likely faulty and you must replace the fan tray.
Place your hand near the exhaust vents at the side of the chassis to determine whether
the fans are pushing air out of the chassis.
