Installing a Fan Module

The four fan modules and the power supplies are hot-swappable if you install a second

(redundant) power supply.

NOTE:

To run the system, the four fan slots must have operating fan units. If you do

not install a module in each slot, the system shuts down in one minute.

NOTE:

The system supports two airflow direction options. You can only use a single

direction in a chassis.

Normal is airflow from the I/O side to the power supply.

•

Reversed is airflow from the power supply to the I/O side.

There are environmental factors that could decrease the amount of time required between

fan replacements. Check these environmental factors regularly. Any unusual environmental

circumstance at the site that causes an increase in temperature and/or particulate matter in

the air might affect performance (for example, new equipment installation).

Remove the fan module from the shipping box.

Use the grab handle to slide the module into the switch fan slot.
