Replacing Modules
Step 1
Remove the fan module that you need to replace as follows:
a) Verify that the fan modules that you are not replacing each have a lit Status (STS) LED (see the following figure for
the location of the LED). If you are replacing a fan module during operations, the other two fan modules must be
operating.
Note If you are replacing the fan module while the chassis is not operating, you can skip this step.

2 Status (STS) LED
3 Handle
b) Pull the fan module handle to slide the module out of the chassis.

connectors on the back side of the module. Also, to prevent any damage to the electrical connectors, prevent
them touching anything that can bend or break them.
c) Place the removed module on an antistatic surface or in an antistatic bag. If possible, repack the module in its packing
materials for safe shipping or storage.
Step 2
Follow these steps to replace the missing fan module within two minutes to avoid a shutdown.
a) Remove the replacement fan module from its packing materials and place it on an antistatic surface.
Hold the module by its handle and do not touch the electrical connectors on its backside. Also, to protect the electrical
connectors, avoid letting them come in contact with anything other than the electrical connectors inside the chassis.
b) Verify that you have the right fan module for the chassis. The correct fan module has one of the following part
numbers:
• N9K-C9300-FAN2-B (port-side exhaust airflow direction and a blue stripe)
• N9K-C9300-FAN2 (port-side intake airflow direction and a burgundy stripe)
4 Colored stripe specifying the airflow direction
(burgundy for the port-side intake direction or blue
for the port-side exhaust direction)
5 Electrical connectors on the backside.
