Carefully unpack the standard detachable antennas.

Screw an antenna into each of the sockets in the access point housing.

Hand-tighten the antennas at the very base of the SMA connectors without 
handling the antenna tips.

Access Point 8250 and Access Point 8750: Position the antennas so they turn out 
and away from the access point at a 45-degree angle. After network startup, you 
may need to adjust the antennas to fine-tune coverage in your area.

Depending on the coverage required for your site, you may want to replace the 
standard detachable antennas with one of the external antennas available for use 
with the access point. See “Selecting and Connecting a Different Antenna Model” 
on page 22.

It is advisable to connect the power and check the Ethernet cables and LEDs before 
installing the unit in a hard-to-reach location. 

The access point complies with the IEEE 802.3af power-over-Ethernet standard. It 
receives power over a standard category 5 straight (8-wire) Ethernet cable. 

There are two ways to supply power to the access point:

n

Use the 3Com Integrated Power-over-Ethernet power supply. In this case, you need 
to supply a second Ethernet cable to connect to the wired LAN. 

Rotate for
best reception.
