Installing the AP-2500 in a Plenum
In an office building, plenum is the space between the structural ceiling and the tile ceiling that is provided to help air
circulate. Many companies also use the plenum to house communication equipment and cables. However, these
products and cables must comply with certain safety requirements, such as Underwriter Labs (UL) Standard 2043:
“Standard for Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in
Air-Handling Spaces.”
The AP-2500 has been certified under UL Standard 2043 and can be installed in the plenum only when the following
conditions apply:
• The AP’s plastic cover has been removed.
• There are two 802.11b cards installed in the card slots OR there is only one 802.11b card installed and the
other card slot is protected with the metal faceplate shipped with the unit from the factory.
NOTE
The AP-2500 using the 5 GHz Upgrade Kit is not certified for plenum installation.
