Nortel Networks recommends that you replace the air filter every three months.
After you install the first 8010co chassis at your site, inspect the air filter monthly
until you can establish an average period of replacement.
If you install a second 8010co chassis in the same equipment rack, the effect of the
total airflow on the filters changes. Inspect the air filters frequently: the average
period of replacement for the lower air filter can differ from that of the upper air
filter because of its proximity to the floor. You may want to replace both filters
according to the shortest average.

Removing and inserting an air filter (8010co chassis only)

Replace an air filter in the 8010co chassis while the switch continues to operate.
To minimize the amount of time that the switch operates without an air filter, have
the replacement filter ready to install before you remove the old one.
