4.1 Air Filter Inspection
The ONS 15454 SDH contains a reusable filter that you should remove and visually inspect
approximately every 30 days, depending on the cleanness of the operating environment. For more
information about filter brackets and air filter installation, see Chapter 1 in the Cisco ONS 15454 SDH

The air filter is made of gray, open-celled, polyurethane foam that is specially coated to provide fire and
fungi resistance. Figure 4-1 illustrates a reusable fan tray air filter in an external filter bracket.
