Replacing the Front Fan Assembly in the NetIron MLX-16
To replace a fan assembly, do the following:
1.
Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located on the
front of the chassis.
2.
Using the flathead screwdriver, loosen the four captive screws that secure the fan assembly to the chassis
front.
3.
Remove the fan assembly from the chassis by grabbing the handle on the fan assembly and pulling it toward
you as shown in Figure 6.9. Pulling the fan assembly unseats the assembly connector from a chassis
connector.
WARNING:
Be careful not to accidently insert your fingers into the fan while removing it from the chassis. The
fan may still be spinning at a high speed.

4.
Insert the new fan assembly into the fan slot and push the assembly in until the face plate is flush with the
chassis. Pushing the assembly in seats the fan connector with the chassis connector.
5.
Secure the fan to the chassis by tightening the four captive screws.
6.
Access the CLI, and enter the
show chassis
command to verify that the fans are operating normally.
Replacing the Fan Tray Assembly in the NetIron MLX-4 and NetIron MLX-8
The NetIron MLX-4 and NetIron MLX-8 have a fan tray assembly accessible from the front of the chassis. The fan
tray assembly pulls air out of the chassis.
NOTE:
If you did not remove the extra shipment screws from the NetIron MLX-4 and NetIron MLX-8 chassis
during installation (see “Removing NetIron MLX-4 Extra Shipment Screws” on page 3-5 or “Removing NetIron
MLX-8 Extra Shipment Screws” on page 3-13), then you will not be able to remove the fan tray assembly. In this
case, you will have to remove the NetIron MLX-4 or NetIron MLX-8 from the rack to remove the shipment screws.
