Cisco Aironet 1131G - Radio access point AIR-LAP1131G-E-K9 User Manual

The 1131AG access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a 
5-GHz 802.11a radio. The 1131G 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.

The auto-sensing Ethernet port accepts an RJ-45 connector, linking the access point to 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 

port is located in a cable bay area that is hidden by the closed top cover (see 

).

Do not attempt to connect a cable with a protective boot to the access point Ethernet port. Because of 
limited space in the connection area, booted connectors might not fit.

The serial console port can be used to monitor the access point power-up sequences using a terminal 
emulator program. The port is located in a cable bay area that is hidden by the top cover (see 

Use an RJ-45 to DB-9 serial cable to connect your computer’s COM port to the access point’s serial 
console port. (Refer to 

 for a description of the console port 

pinouts.) 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.

Do not attempt to connect a cable with a protective boot to the access point console port. Because of 
limited space in the connection area, booted connectors might not fit.

The access point has three LEDs to indicate Ethernet activity, radio activity, and status indications (see 

). For additional information, refer to the 

 or the 

.

The Status LED provides general operating status and error indications (top cover closed).

The Ethernet LED is located in the cable bay area under the access point top cover. This LED signals 
Ethernet traffic on the wired Ethernet LAN and provides Ethernet error indications. 

The Radio LED is located in the cable bay area under the access point top cover. This LED signals 
that wireless packets are being transmitted or received over the radio interface and provides radio 
error indications. 

The access point cover must be closed to view the Status LED but the cover must be open to view the 
Ethernet and the Radio LEDs.
