Replacing fan assemblies
You can replace a fan or a fan control module while the router is powered on and running. The fans
and fan control modules are located on the rear panel of the router.
NOTE
Fan trays are hot swappable. However, a hot-swap procedure should be completed within five
minutes so the device will continue to function correctly without any fans. It is recommended that
you disconnect the power supply from AC or DC power before installing or removing the fan tray.
While fan assemblies are being replaced, and there is an increase or decrease in fan-speed due to
that, syslogs or console messages are not generated.
