AP 2800 and AP 3800
have similar physical dimensions with only slight differences in physical
appearance mostly to accommodate the different features like modularity and
Multigigabit support resulting in slight differences in width.
There are many
different installation options available depending upon the business
requirements. Brackets are available from Cisco as well as third-party
companies. During the ordering process, the customer may choose one of two
brackets (but not both). Each bracket is a zero-dollar ($0) option at the time
of configuration. If the customer does not choose a bracket, the selection
default is AIR-AP-BRACKET-1, which is the most popular for ceiling
installations. The other choice is a universal bracket that carries part number
The AP 2800 and AP
3800 is noticeably heavier than the AP 2700 and AP 3700. This is due to the
powerful design of the components used, which include a dual core processor, 12
radio transceivers, additional memory and processor power as well as additional
Ethernet capability including mGig on the AP 3800 and optional module support.
The mounting brackets
and ceiling rails easily handle the extra weight and the intent was to make a
very robust Access Point without the need for vent holes and to allow the
product to be used in industrial and manufacturing areas as well as commercial
Figure 1. Access Point
If the AP will be
mounted directly to a ceiling on the gridwork, then AIR-AP-BRACKET-1 mounts
flush and has the lowest profile. However, if the AP will be mounted to an
electrical box or other wiring fixture, or inside a NEMA enclosure or perhaps
wall mounted, then AIR-AP-BRACKET-2 is a much better choice. The extra space in
the bracket allows for wiring, and the extra holes line up with many popular
electrical boxes. When mounting the bracket to the ceiling gridwork, some
ceiling tiles are recessed. For this reason, two different styles of ceiling
clips, recessed and flush rails, are available.
For new installations
AIR-BRACKET-2 is recommended as it provides a little extra room and accomodates
earlier access points with modules, so it truly is a universal bracket.
Figure 2. Different clips
are available for attaching to ceiling grid work
When mounting APs to
ceiling channel rails such as the ones shown in Figure 14, an optional channel
adapter is used: AIR-CHNL-ADAPTER. It comes in a two-pack and attaches to the
ceiling grid clip above.
Thin rail or
sometimes referred to as recessed ceiling rails often look like as shown.

Mounting an AP
Directly into the Tile Using Optional AIR-AP-BRACKET-3
This bracket is not
compatible with the AP 2800 and AP 3800 Series.
If you have this
bracket currently installed and are migrating to the newer AP 2800 and AP 3800
series, you may be able to still use the existing tile and leverage the new
in-tile mount available from Oberon Wireless (a Cisco partner).
here is an overview of the existing AIR-BRACKET-3 so you may understand it
better should you encounter it within your deployments. Many hospitals and
other carpeted Enterprise environments prefer a more streamlined look and wish
to install the AP directly into the tile. This can be done on prior Cisco AP
products using the optional Cisco AIR-AP-BRACKET-3.
When using this
bracket, the "beauty ring" is used as the template to cut the tile which can be
cut using a carpet knife or electric tool such as a rotary cutting tool, e.g.,
Dremel or Rotozip. Cisco does not offer custom cut tiles as there are simply
too many different styles and the tiles are easy to cut.
The AP is fully
supported above the tile with a metal rail that extends the length of the tile.
This supports the AP should the tile become wet or otherwise fail. A mechanical
set screw pulls the AP tight to the ceiling and locks it into the bracket.
Additionally, physical security of the AP can be maintained by the use of a
Kensington style lock, but once installed it is difficult to remove the AP
without removing the tile as the AP will not slide out from the front side of

This bracket fits
the AP-1040, 1140, 1260, 1600, 2600, 3500, 3600 and 3700 Series Access Points;
however, it is not compatible with the 2800 and 3800 series.
