About Airespace AP Connectors

The Airespace AP has the following external connectors:

• One RJ-45 jack, used for connecting the Airespace AP to

the Airespace Switch.

• One 48 VDC power input jack, used to plug an optional

factory-supplied external power adapter into the Airespace AP.

• Three reverse-polarity TNC antenna jacks, used to plug

optional external antennas into the Airespace AP--two for an

802.11b radio, and one for an 802.11a radio.

Note: No 802.11a external antennas are currently certified

or available in this release. Contact Airespace, Inc. for a list of

FCC-approved 802.11b external antennas.

The Airespace AP communicates with an Airespace Switch using

standard CAT5 (Category 5) or higher 10/100 Mbps unshielded

twisted pair cable with RJ-45 connectors. Plug the CAT5 cable

into the RJ-45 jack on the side of the Airespace AP.

Note that the Airespace AP can receive power over the CAT5

cable from the Airespace Switch or other equipment. Refer to

About Power Over Ethernet for more information about this

option.

The Airespace AP can be powered from an optional factory-

supplied external AC-to-48 VDC power adapter. If you are

powering the Airespace AP using an external adapter, plug the

adapter into the 48 VDC power jack on the side of the Airespace

AP.

The Airespace AP includes two 802.11a and two 802.11b high-

gain internal antennas, which provide omnidirectional coverage.

However, the Airespace AP can also use optional factory-supplied

external high-gain and/or directional antennas; one for an 802.11a

radio and two for an 802.11b radio. When used with external

antennas, each Airespace AP radio supports diversity, if enabled.

When you are using external antennas, plug them into the reverse-

polarity TNC jacks on the side of the Airespace AP.

Note: No 802.11a external antennas are currently certified

or available in this release. Contact Airespace, Inc. for a list of

FCC-approved 802.11b external antennas.

Note: The Airespace APs must use the factory-supplied

internal or external antennas to avoid violating FCC regulations

and voiding the user’s authority to operate the equipment.
