Altitude™ 4521 Series Access Point Installation Guide

Above the Ceiling (Plenum) Installation
An above the ceiling installation requires placing the Access Point above a suspended 
ceiling and installing the provided light pipe under the ceiling tile for viewing the status 
LED of the unit. An above the ceiling deployment enables installations compliant with drop 
ceilings, suspended ceilings and industry standard tiles from .625 to .75 inches thick. 
NOTE
The Access Point is Plenum rated to UL2043 and NEC1999 to support above the ceiling 
installations. To ensure UL compliance and proper Access Point operation within the Air Handling 
Plenum, the Access Point must be installed with the bottom surface of the unit in contact with the un-
finished surface of the ceiling tile. Placing the product on the ceiling tile will facilitate the positioning of 
the light pipe. Placement of the product in the Air Handling Plenum off of, or away from, the unfinished 
surface of the ceiling tile is not UL approved and certification of UL2043 compliance would be void in 
that case.
CAUTION
Extreme Networks does not recommend mounting the Access Point directly to suspended 
ceiling tile with a thickness less than 12.7mm (0.5in.) or a suspended ceiling tile with an unsupported 
span greater than 660mm (26in.).
The mounting hardware required to install the Access Point above a ceiling consists of:
●
Light pipe
●
Badge for light pipe
●
Decal for badge
To install the Access Point above a ceiling: 
1 If possible, remove the adjacent ceiling tile from its frame and place it aside.
2 If required, install and attach a security cable to the Access Point’s lock port.
3 Mark a point on the finished side of the tile where the light pipe is to be located.
4 Create a light pipe path hole in the target position on the ceiling tile.
5 Use a drill to make a hole in the tile the approximate size of the Access Point LED light 
pipe.
