Replacing a Fan Tray
The fan tray is designed to be removed and replaced while the system is operating without causing an electrical
hazard or damage to the system if the replacement is performed within one minute.
If you do not have the appropriate replacement fan tray, leave the original fan tray in its slot to preserve the
designed airflow for the switch until you have the replacement fan module.
Statement 263—Fan Warning
The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers,
and other objects away from the openings in the fan assembly's housing.
Warning
To replace a fan tray, follow these steps:

• Verify that you have an antistatic surface or bag for placing the fan module that you remove from the
chassis.
• Verify that the replacement fan tray has the correct direction of airflow (it has the same coloring as the
other fan and power supply modules in the same chassis).
Step 1 Remove the fan tray that you are replacing as follows:
