Air filter removal and replacement
You can remove and replace an air filter when it gets too clogged with dirt and dust to operate efficiently. You should perform regular
physical inspections to determine how often to replace the air filter. Maintaining clean air filters ensures optimal airflow through the
devices.
Based on the traffic and particulate levels of the installation location, the site operator should determine the appropriate replacement
intervals for the air filter.
If the air filter were to become sufficiently blocked, the thermal policy of the device would notify the administrator of an environmental
issue with the system.
If a site-specific interval cannot be determined by the site operator, the filter should be replaced on an interval of every 3 months.
The filters are single use and non-recyclable. They have a UL fire rating of FLAME RETARDANT, UL 94HF-1 UAF and PPI
measurement of 25.
The chassis is shown in a four-post recessed-mount rack configuration, but the mounting of the air filter is the same for any rack mount.
Refer to the following illustration.
