into contact with and damaging the connectors.
Installing a Fan Module
Before you begin
• A fan slot must be open and ready for the new fan module to be installed.
• You must have a new fan module on hand and ready to install within one minute of removing the original
• The new fan module must have the same airflow direction as the other fan and power supply modules
Step 1
Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the
open fan slot in the chassis.
Step 2
Slide the fan module into the slot until it clicks in place.
Step 3
Verify that the Status (STS) LED turns on and becomes green.
Replacing a Power Supply Module
The switch requires two power supplies for redundancy. With one power supply providing the necessary
power for operations, you can replace the other power supply during operations so long as the new power
supply has the same airflow direction as the other modules in the chassis.
You can replace a power supply with another supported power supply that has the same power source type
and the same wattage rating as the other installed power supply. Additionally, the airflow direction of the
power supply must match or conform to the airflow direction of the installed fan modules. For the airflow
direction used by the switch, see the coloring of the fan modules.
Replacing an AC Power Supply
You can replace an AC power supply during operations so long as the other power supply provides to the
switch.
Before you begin
Note
You can determine the airflow direction by looking at the coloring of the latch on each power supply. AC
power supplies with burgundy latches have port-side intake airflow direction, and power supplies with blue
latches have port-side exhaust airflow direction.
