Replacing the Controller Fan

You can hot-swap the controller fan canister (replace it while the controller module
is running), as long as you complete the exchange within 15 minutes. This time limit
applies to the total time that the fan canister is out of the chassis, beginning when
you remove the failed unit and ending when you install the new one.
Caution – Do not run the controller module without adequate ventilation and
!
cooling to the controllers. Leaving the unit running without proper cooling to the
controllers may damage their circuitry. If there will be a delay of more than 15
minutes from the time you remove the controller fan canister and insert a new one,
shut down the controller module. This will prevent the controller from overheating.
1. Remove the controller module front panel.
See Section 5.1.1 "Removing the Front Panel" on page 5-2.
2. Loosen the thumbscrew (counter-clockwise) on the fan canister (
If the thumbscrew is too tight, use a flat blade screwdriver to loosen it.
