The cooling modules are hot-swappable and can be replaced while the system is powered
on and operational.

a. Unseat the faulty cooling module. Wait until the blades have fully stopped before
proceeding to the next step.
b. Hold the cooling module handle and slowly slide the module out of the chassis.
Place the cooling module in an antistatic bag or a grounded antistatic mat.
3.
Install the new cooling module.
4.
Before installing, ensure the correct handle is attached to the new module.
The upper FAN3 modules have a different handle from the lower FAN3 modules. The
lower modules are recessed deeper in the chassis and therefore require a deeper
handle. The deeper handle has a circular cutout so that air flow is not obstructed to
the FAN3 module directly above.
Depending on whether you are replacing a lower or an upper FAN3 module, you might
need to change the metal handle. The handle for the upper FAN3 module is attached
with two screws. The handle for the lower FAN3 module is attached with four screws.
Once the correct handle is attachd to the new module, insert the module into the slot
until it is seated.
Close the cooling module door.
