A QFX3008-I Interconnect device bottom air filter is located beneath the bottom fan
tray and front panel display. Two captive screws on either side of the air filter door secure
the air filter in the chassis.
CAUTION: Do not run the device for more than 2 minutes without the air filter
in place.
CAUTION: Always keep the air filter in place while the device is operating,
except during replacement. Because the fans are very powerful, they could
pull small bits of wire or other materials into the device through the unfiltered
air intake. This could damage device components.
