Replacing a Chassis Air Filter
Fans in the BlackDiamond 20808 switch draw cooling air in through the lower front of the chassis and
exhaust air through vents at the upper back. A replaceable filter immediately below the front fan tray
filters air as it enters the chassis.
Required Tools
You need a #2 Phillips screwdriver to replace the chassis air filter in the BlackDiamond 20808 switch.
Replacing the Air Filter
To replace the filter:
1 At the front of the switch, completely loosen the captive retaining screw at each side of the
ventilation panel (Figure 72) and remove the panel from the front of the switch.
