2.9 Periodic Maintenance
Periodic maintenance consists of cleaning of the bridge’s two internal air filters.
This should be done at least once per year, and more often as required by the
bridge’s environment.

Cleaning the Filters
You will have to remove operating power to the bridge before cleaning the filters.
Contact your network administrator and make sure your application will not be
adversely affected. Then remove power to the bridge.
Remove the filters, clean them with a detergent solution suitable for your site, and
reinstall them. The filter locations are described below.
Upper Filter
Remove the four screws securing the bridge’s enclosure cover, and remove the
cover. The upper filter is accessible behind the bridge’s front panel.
Lower Filter
Remove the two screws securing the bridge’s power supply, and move the supply
away from the rest of the bridge assembly. The lower filter is accessible behind
the power supply’s front panel.
