Replacing a Fan Module
(For NCS 5001, NCS 5002, and NCS 5011) 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 five minutes. If you do not have the appropriate replacement fan module, leave the original fan module in its slot to preserve the designed airflow for the router until you have the replacement fan module.
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. Statement 263 |
