Single Or Dual-Radio Operation; Antennas Supported; Ethernet Port; Console Port - Cisco Aironet 1240AG Series Hardware Installation Manual

Chapter 1 Overview

Single or Dual-Radio Operation

The 1242AG access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a
5-GHz 802.11a radio. The 1242G access point supports a single 2.4-GHz 802.11g radio. Each radio uses
dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.

Ethernet Port

The auto-sensing Ethernet port (see
your 10BASE-T or 100BASE-T Ethernet LAN. The access point can receive power through the Ethernet
cable from a power injector, switch, or power patch panel. The Ethernet MAC address is printed on the
label on the back of the access point (refer to the
page

Console Port

The serial console port can be used to monitor the access point power-up sequences using a terminal
emulator program. The port is located on the end of the unit (see
cable to connect your computer's COM port to the access point's serial console port. (Refer to
Appendix E, "Console Cable Pinouts,"
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.
After completing your configuration changes, you must remove the serial cable from the access point.
