Cisco Aironet 1200 Series Access Point Hardware Installation Guide
OL-2155-02
Chapter 1 Overview
Key Features
Antenna Connectors
The access point supports two antenna connectors on the back of the unit for the 2.4-GHz radio. The
5-GHz radio supports only integrated antennas.
2.4-GHz Radio
The access point provides two reverse-polarity TNC (R-TNC) connectors that you can use to connect a
single antenna or dual diversity antennas to provide coverage for your wireless LAN area. Diversity
coverage helps maintain a clear radio signal between the access point and wireless client devices. Just
as you can improve signal clarity on your car radio at a stoplight by creeping ahead a few inches, the
access point can improve signal quality by choosing the antenna that is receiving the best signal from a
client device.
Ethernet and Console Ports
Ethernet Port
The Ethernet port accepts an RJ-45 connector, linking the access point to your 10/100 BASE-T Ethernet
LAN. The access point can receive power through the Ethernet cable from a switch with inline power,
from a power patch panel, or from the access point’s 1200 series power injector.
Console Port
The console port provides access to the access point’s management system using a terminal emulator
program. Use an RJ-45 to DB-9 serial cable (refer to Appendix C, “Console Cable Pinouts”) to connect
your computer’s COM port to the access point’s serial console port. Assign the following port settings
to a terminal emulator to open the management system pages: 9600 baud, 8 data bits, No parity, 1 stop
bit and no flow control.
Metal Enclosure
The access point uses a metal enclosure having adequate fire resistance and low smoke-producing
characteristics suitable for operation in a building’s environmental air space in accordance with Section
300-22(c) of the NEC, such as above suspended ceilings. The access point also supports an industrial
temperature operating range (refer to Access Point Specifications, page 1-10).
Note If you plan to mount the access point in environmental air space using a 5-GHz radio, Cisco recommends
that you mount the access point horizontally with its antennas pointing down. Doing so will result in the
access point complying with regulatory requirements for environmental air space with the 5-GHz radio
installed.
