Air Flow Recommendations
Air flow for the switches differs slightly for each model. Air may be drawn through the chassis using fans
or the switch may be convection cooled. Refer to the diagrams below for more information.
Chassis Air Flow - OS6855-24
Note
.
A filter is NOT required under most operating conditions. If a filter is used it must be changed on a
minimum quarterly basis. Under extreme conditions a more frequent schedule may be required. Failure to
maintain a regular filter maintenance schedule may cause particle build up resulting in restricted airflow
and increased operating temperature. Refer to the Alcatel-Lucent price list for information on replace-
ment filters.
1. Air Intake.
The chassis fans pull air
from the main air intake vents located in
the right-hand panel of the chassis.
(optional filter)
2. Air Flow.
The air from the
intake vent is directed through the
chassis past the circuit board. This
air flow provides required cooling
for chassis components.
3. Air Exhaust.
The air flow is
exhausted through the fan exhaust
vents at the left-hand and front of the
chassis.
