Hardware Features
Dual-Radio Operation
The access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a 5-GHz
802.11a 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.

default SSID. You must create an SSID and enable the radios before the access point allows wireless
associations from other devices.

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 provides access to the access point's command-line interface (CLI) using a
terminal emulator program. The port is located on the end of the unit (see
DB-9 serial 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.
