SELECTING AND CONNECTING A DIFFERENT ANTENNA MODEL
The standard detachable antennas supplied with the Access Point 7250 are suitable
for a broad variety of environments. If you require a different type of antenna for the
Access Point 7250, several options are available by model number from the 3Com
Web site (www.3Com.com).
For each of the antenna models, you will need either a 6-foot accessory cable
(model 3CWE480) or a 20-foot accessory cable (model 3CWE481) to provide the
transition from the SMA connector on the access point to the N-type connector
on the antenna.
To ensure the physical safety of anyone near the antenna and to prevent damage
to the access point, follow the building codes for antenna installations in your area.
Antennas can be connected to either side of the access point after the standard
detachable antennas have been removed, as shown below.
Important Note: For FCC regulatory compliance reasons, in the United States,
Canada, and other countries governed by FCC guidelines, external antennas can
only be used in an access point operating temperature range of 15° C - 40° C
(59°
F - 104° F)
If the access point is used with an external antenna, you must also purchase an
antenna cable. For maximum efficiency, use the shortest antenna cable possible.
Antenna cables induce signal loss, which will limit the radiated power output
and range of the access point. Of the options available, we recommend the
3Com 6-foot Antenna Cable (3CSE480).
