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.
Removing an AC Power Supply
To remove an AC power supply, you must first disconnect the power cable and then remove the module from
the chassis.
Before you begin
• To replace a power supply during operations, you must have a functioning power supply providing power
• Ensure that the chassis is grounded. For grounding instructions, see

to the switch while you replace the other power supply. If there is only one power supply installed in the
switch and you need to replace it, install the new power supply in the open slot and power it up before
removing the original power supply.
