Replacing fan assemblies in 16-slot routers
Brocade MLX and Brocade 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.
Brocade MLXe 16-slot routers have two fan assemblies accessible from the rear of the router.
You can remove and replace a fan assembly while the router is powered on and running.
CAUTION
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.

assembly toward you as shown in Figure 232 and Figure . Pulling the fan assembly unseats the
fan connector from the router connector.
