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.
Replacing fan assemblies in all 32-slot routers
This section describes how to replace fan assemblies in MLXe 32-slot routers.
CAUTION
Removal of Brocade NetIron MLXe Series 32 rear fan modules allows access to bus bars and backplane. Avoid contact with
these parts. There are hazardous energy levels at these locations.
A 32-slot router has ten fan assemblies located at the rear of the router. They are numbered as indicated in the following figure.
You can remove and replace a fan assembly while the router is powered on and running.
NOTE
To avoid overheating of the router, remove one fan assembly at a time, and replace it promptly. Wait for the LED on the fan
assembly being replaced to turn green before replacing another fan assembly. Do not remove all fans from the device at once.
