6. Check the fan status LED in the lower left corner of the faceplate. It will light red momentarily when power is applied, then change
to green when the fan comes up to speed.

Replacing fan assemblies in 16-slot routers

Brocade MLX and NetIron XMR 16-slot routers have one fan assembly accessible from the front of the router and two assemblies
accessible from the rear of the router.
You can remove and replace a fan assembly while the router is powered on and running.
To avoid overheating of the 16-slot router, remove one fan assembly at a time, and replace it promptly. Do
not remove all fans from the device at once.
To replace a fan assembly, you need the following:
•
A new fan assembly, which you can order from Brocade.
•
A small flat-blade screwdriver.
•
An ESD wrist strap with a plug for connection to the ESD connector on the router.
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
Replacing the rear fan assemblies in 16-slot routers
The instructions for replacing the rear fan assemblies in the 16-slot router apply to both standard) and high-speed fan assemblies.
Perform these steps to replace a rear fan assembly.
1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on the router.
2. Loosen the four captive screws that secure the fan assembly to the router.
3. Remove the fan by inserting your fingers underneath the fan assembly and pulling the assembly toward you as shown in
Figure 157. Pulling the fan assembly unseats the fan connector from the router connector.
Be careful not to insert your fingers into the fan while removing it. The fan may still be spinning at a high
speed.
