Installing and Removing a Module
Appendix A
A-10
To protect the chassis and maintain air flow through the chassis, you must
install filler plates (5110-FP) in all empty module slots. Filler plates also
aid in cooling the chassis when a fan chassis is connected to the chassis.
ATTENTION: Install filler plates in empty slots. If you do not,
air will not flow properly through the chassis and noise
immunity will be reduced.
Follow the steps below to install filler plates.
1. Check the module documentation to locate the empty slot or slots.
2. Attach the filler plate to the empty slot.
a. Place the filler plate over
the empty slot.
b. Tighten the thumbscrews.
