The lower section of the top front panel houses the air filter, which cleans intake air drawn in by the blower. Three cutouts in the top of the panel contain semiopaque black plastic windows, through which the three system
LEDs are visible when they are on. EMI shielding surrounds the entire outer edge of the top front panel. The shielding acts as a spring, and compresses when you push the panel into the chassis to keep the panel fitted tightly into the chassis opening.
The bottom front panel is vented and covers the lower area of the top front panel that houses the air filter. The bottom front panel fits over the lower section of the top front panel and attaches to the chassis with ball studs. You must remove the bottom front panel before you can remove the top front panel. You can remove the bottom front panel while the system is operating to access or clean the air filter, but always turn system power off before removing the top front panel.
The chassis panels provide shielding against electromagnetic interference (EMI) and work with the blower and air filter to maintain a constant flow of cooling air through the chassis. Replace the chassis panels if they become warped or broken.
