Removing the Fan Tray

The fan Tray is designed to be removed and replaced while the system is operating without presenting

Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray. Statement 258

If you are upgrading your chassis from a fan tray 1 (low speed) to a fan tray 2 (high speed) and your
Step 1
chassis is equipped with a Supervisor Engine 2, you need to check that the current chassis configuration

configuration problems, such as power supply compatibility and power sufficiency.
If the system does not detect any configuration issues, a message is displayed saying that it is OK to
change the fan trays. If your chassis has either a Supervisor Engine 32 or a Supervisor Engine 720, skip
this step and proceed to Step 2.
Locate the fan assembly in the chassis as follows:
