Install the air filters
For compatibility with Network Equipment Building System (NEBS), this switch
requires a filtered air supply. The switch is shipped with air filters which must be
installed in each of the fan units.
To install an air filter:
1. Using a flat screwdriver, undo the captive screws on the front of the fan
unit.
2. Slide the fan unit out of its cage. The internal power connection is quite
solid, so pull firmly on the captive screws.
3. Insert the air filter into the narrow slot between the front grill of the fan
unit and the fan. Position the air filter with the plastic frame towards the fan
and the pull tab to the top. The air filter should fit snugly.
4. Slide the fan unit back into its cage, making sure that the air filter and the
pull tab are clear of any contact points.
5. Press the fan unit firmly into place and tighten the captive screws on the
front of the fan unit.
