Installing and Removing Cooling Fans
The 5 CPU fan units are hot swappable. You can remove and install a fan unit at the rear of the appliance
without shutting down the appliance.
Before You Start:
To replace a fan unit, you need:
 Physical access to the appliance
 Replacement fan unit
 Flat headed screwdriver
Caution - Components inside the appliance can overheat if they are not
cooled even for a short period of time. If you replace a failed fan unit, and do
not completely remove power to the appliance, do not let the appliance run
without a fan unit for longer than necessary.
To replace a fan unit:
1. Find the fan grille at the rear of the appliance and the retaining screw that secures it ("Check Point
21400 VSX Rear Panel" on page 19).
The fans are numbered as in the diagram.
2. Use the screwdriver to loosen the retaining thumb screw by turning it counterclockwise.
3. Remove the fan grille:
a) Use your fingernail to move the grille to the right.
b) Pull out the grille.
