Chapter 3 - Installing
3. Remove the adhesive from the air gasket (“L” shaped foam) and place it on top of the workstation
as shown in the following “Air flow and air dam arrangement” figure. The adhesive keeps the
gasket in place. The gasket stops the exhaust air from re-circulating around the workstation.
4. Remove the adhesive from the air dam (clear flat sheet with two chamfered corners). Cover the
ventilation slots at the bottom of the electronic enclosure near the front side of the workstation, with
the chamfers downward. For this workstation, the ventilation slots to be left open (uncovered) are
on the right side. The dam causes cooling air to be drawn down from the back panel area (refer to
the following Air flow and air dam arrangement figure).
5. Test that the electronics enclosure can be closed and opened without binding. With some
workstations, it may be necessary to trim or augment the air gasket.

A Local Control Network Processor (LCNP) board and LCN Media Access Unit (MAU) are no
longer used if the Workstation has been upgraded to be an ELCN node.
