The Acme Packet 4500's air filter removes airborne particles before they are drawn
into the Acme Packet 4500 chassis. To prevent system malfunction and prolong the
life of the system's cooling components:
clean or replace the fan filter every three months
•
clean the air inlets once a week.
•
Cooling maintenance encompasses cleaning the fan module and cleaning the air
inlets on the front of the Acme Packet 4500's chassis. Cleaning the fan module
requires that you remove the module itself. If you are not shutting down the Acme
Packet 4500, this procedure must be performed quickly or else the system may
overheat and cause packet processing to stop.
