3.7.2 Replacing the Air Filter of the USG9560
This section describes the procedure for replacing the air filter on the USG9560.
Precautions
To ensure good heat dissipation and ventilation for the system and to prevent the
accumulation of dust on an air filter, you need to clean the air filter regularly. It is
recommended that an air filter be cleaned at least once every three months and be replaced
once every year. When an air filter is placed in the dusty environment, it needs to be cleaned
more frequently.
Configuring a Cleaning Cycle for the Air Filter
You can configure a cleaning cycle using the
dustproof check-timer day
days
command in
the system view.
When the air filter has already been running for a period of time, the system generates an
alarm to remind you to clean the air filter. You can use the
reset dustproof run-time
command to clear the alarm and re-count the runtime of the air filter. The default cleaning
cycle is 90 days. The value 0 indicates that the air filter monitoring is stopped.
