Figure 12: Air Filter Carrier (7750 SR-a4)
The air filter prevents large particles, debris, and dust from entering and circulating through
the system. The air filter must always be in place while the chassis is powered.
Filters should be inspected monthly and replaced when accumulated dust is present. The
replaceable filters can be ordered separately, as described in
.
Removing and Replacing an Air Filter on page 189
for more information.
Impedance Panels
Impedance panels are required on all empty card and component slots to prevent excess dust
accumulation and to help control airflow and electromagnetic interference, and for safety
reasons. Impedance panels do not have board components or connector pins.
