You can remove and replace a fan assembly while the NetIron MLX-16 chassis is powered on and running.
CAUTION:
To avoid overheating of the NetIron MLX-16 chassis, remove only one fan assembly at a time, and
replace it promptly. Do not remove all fans from the chassis at one time.
To replace a fan assembly, you need the following:
•
A new fan assembly, which you can order from Foundry
•
A small flathead screwdriver
•
An ESD wrist strap with a plug for connection to the ESD connector on the NetIron MLX Series chassis
WARNING:
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
Replacing the Rear Fan Assemblies 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 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 from the chassis by inserting your fingers underneath the fan assembly and pulling the
assembly toward you as shown in Figure 6.8. Pulling the fan assembly unseats the fan connector from a
chassis connector.
WARNING:
Be careful not to insert your fingers into the fan while removing it from the chassis. The fan may still
be spinning at a high speed.

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 assembly to the chassis by tightening the four captive screws.
6.
Access the CLI, and enter the
show chassis
command to verify that both fans are operating normally.
