Removing a Fan Module
Statement 263
— Fan Warning
The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers,
screwdrivers, and other objects away from the openings in the fan assembly's housing.
Warning
Step 1 On the fan module that you are removing, press the two sides of the fan module handle next to where it connects to the
fan module and pull on the handles enough to unseat it from its connectors.
Step 2 Holding the handle, pull the module out of the chassis.
Do not touch the electrical connectors on the back side of the module and prevent anything else from coming
into contact with and damaging the connectors. Caution
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
fan module if the switch is operating.
• The new fan module must have the same airflow direction as the other fan and power supply modules
installed in the switch.
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
(AC, DC, HVAC, or HVDC) and the same wattage rating as the other installed power supply. Additionally,
