Removing a Fan Module
Warning
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray.
Statement 258
Caution Before you remove a fan module, ensure that the module that you are going to install in the open slot has
the same direction of airflow as the module that you are removing to avoid over heating the switch and
causing it to shutdown. If the module that you are removing has a black stripe for back-to-front airflow,
the new module must also have a black stripe. If the module that you are removing does not have a black
stripe, then the new module must also not have a black stripe.
To remove a fan module, follow these steps:
Step 1 Loosen the captive screws on the fan module by turning them counterclockwise, using a flat-blade or
number 2 Phillips screwdriver if required.
Step 2 Grasp the handle of fan module and pull it outward.
Step 3 Pull the fan module clear of the chassis.
Installing a Fan Module
Caution Before installing the new fan module, ensure that the module is marked for the same direction of airflow
as all of the other modules installed in the switch. If the installed modules have a black stripe for
back-to-front airflow, then the new module you are installing must have a black stripe. If the installed
modules do not have a black stripe (front-to-back airflow), then the module that you are installing must
also not have a black stripe. If all of the modules are not taking in cold air from the cold aisle, the switch
can overheat and shutdown.
To install a fan module, follow these steps:
Step 1 Hold the fan module with the LED at the bottom (Cisco Nexus 5596 or Cisco Nexus 5020) or right (Cisco
Nexus 5548 or Cisco Nexus 5010).
