Replacing fan assemblies in 16-slot routers
Brocade MLXe Series 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.
NOTE
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.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in place. If you run the chassis with
an uncovered slot, the system will overheat.
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.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm 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 the
following figure. Pulling the fan assembly unseats the fan connector from the router connector.
DANGER
Be careful not to accidently insert your fingers into the fan tray while removing it from the chassis. The fan may still be
spinning at a high speed.
