3.7.1 Replacing the Air Filter of the USG9580
This section describes the procedure for replacing the air filter on the USG9580.
Precautions
To ensure proper heat dissipation and ventilation for the system and to prevent the
accumulation of dust in the air filter, clean the air filter at least once every three months and
replace it once a year. If the environment is especially dusty, clean the air filter more
frequently.
Configuring a Cleaning Cycle for the Air Filter
You can configure a cleaning cycle for the air filter on the chassis 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.
NOTE
The air filter does not have memory. All monitored information is saved on the MPU, which may be inserted,
removed, switched, or replaced at any time. Therefore, the monitoring cycle may differ from the set cycle.
However, this does not affect the monitoring function.
