I have a additional fan and power supply kit for our new 4500-X core switch. I wanted to change the fan's but I got en error message on the console line and the fan indicated the red light.
The log sends following error
Feb 23 09:47:02.416: %C4K_IOSMODPORTMAN-4-AFANTRAYREMOVED: Fan tray 5 has been removed Feb 23 09:47:17.420: %C4K_IOSMODPORTMAN-6-AFANTRAYINSERTED: Fan tray 5 has been inserted Feb 23 09:47:19.420: %C4K_IOSMODPORTMAN-4-AFANTRAYBAD: Fan tray 5 has failed Feb 23 09:47:19.420: %C4K_CHASSIS-3-SUPERVISORFANTRAYPARTIALFAILURE: A fantray, among the currently installed fantrays, is not functioning.

Any ideas or procedures for changing the fans and the Power Supplies? Is there an command to change in the config? Or is the change only possible with a powerd-off Switch?
The chassis determines which airflow direction is correct by polling all of the fan assemblies and the power supplies. The airflow direction for all of the devices must be the same. If the airflow direction of the replacement fan assembly does not match the other fan assemblies airflow direction or the power supply airflow direction, the system software shuts down the power supply and generates an error message to the console.
