The air filter has two parts: a reusable metal carrier, and a replaceable filter. The filter is
designed to snap into the carrier, and has a polarity tab. Replacement filter units can be
ordered separately from Alcatel-Lucent. Filter replacements are individually bagged, five to
a box.
Note: Each replacement filter is packaged in an oversized plastic bag to allow the dirty filter
to be placed in the bag for disposal without releasing the dust.
Alcatel-Lucent recommends that you inspect the air filter monthly. If dirt and dust
accumulation are found, replace the air filter.
