Replacing a Fan Module During Operations
All fan and power supply modules must have the same airflow direction or else an error can occur with the
switch overheating and shutting down. You can determine the airflow direction of a fan module by the color
of the stripe on the front of the module. If the fan module has a red stripe for port-side intake airflow, the
power supplies must have red coloring for the same airflow direction. To avoid over heating the switch, make
sure that the fan modules are positioned this way:
• For port-side intake airflow with red coloring, position the ports in a cold aisle.
Before you begin
Before you can replace a fan module, ensure that these conditions exist:
• There are four functioning fan modules in the other fan slots. In order to replace a fan module during
• The replacement fan module must have the same airflow direction as the other modules in the chassis.
If you must replace the fan module during operations and the above conditions are not met, leave the fan
module that you need to replace in the chassis to preserve the designed airflow until you have the required
module.
Procedure
Step 1
Remove the fan module that you need to replace.
Step 2 Use these steps to replace the missing fan module within two minutes to avoid a shutdown.

operations, there must be three fan modules circulating air in the chassis at all times. The other fan module
is redundant and can be replaced.
