Maintaining the Cooling Components
The Acme Packet 3900 air filter removes airborne particles before they are drawn into
the Acme Packet 3900 chassis. To prevent system malfunction and prolong the life of
the system’s cooling components, do these things:
•
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 3900 chassis. Cleaning the fan module requires that
you remove the module itself. If you are not shutting down the Acme Packet 3900,
this procedure must be performed quickly or else the system may overheat and cause
packet processing to stop.
This maintenance should be performed alongside other preventive maintenance to
take place within a planned maintenance or downtime window, during off-peak hours.
