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.

The LED board contains the three LEDs that report system software (Normal) and

power supply (Upper Power and Lower Power) status through semi-opaque panels on

the front of the chassis. Figure 2 shows the three system status indicators.
