Wireless LAN Access Point 8250
(3CRWE825075A), Wireless LAN Access
Point 8750 (3CRWE875075A) and
802.11g Wireless LAN Access Point
Upgrade Kit (3CRWEGMOD75A) may
only be used with external antennas
under the following conditions:
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). In these coun-
tries only external antennas with a gain of
up to 8 dBi may be used. This includes the
antennas listed in the table below.
In the European Community, you may use
the antennas listed in the table as well as
the 3Com 13 dBi Sector-Panel Antenna
(3CWE495). The temperature restriction
does not apply.
•
If the access point is used with an exter-
nal 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 out-
put and range of the access point. Of the
options available, we recommend the
3Com 6-Foot Antenna Cable (3CWE480).
