Chapter 1 Overview
Hardware Features
Ethernet Port
The auto-sensing Ethernet port (see Figure TBD ) accepts an RJ-45 connector, linking the access point
to your 10BASE-T, 100BASE-T, or 1000BASE-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 “Locating the Product Serial
Number” section on page -viii).
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 Figure 1-2). 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 Appendix E, “Console Cable Pinouts,” 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.
Note After completing your configuration changes, you must remove the serial cable from the access point.
LEDs
The access point has three LEDs (see Figure 1-2) to indicate Ethernet activity, radio activity, and status
indications (refer to the “Checking the Access Point LEDs” section on page 6-2 for additional
information).
• The Status LED provides general operating status and error indications.
• The Ethernet LED signals Ethernet traffic on the wired Ethernet LAN and provides Ethernet error
indications.
• The Radio LED signals that wireless packets are being transmitted or received over the radio
interface and provides error indications.
Power Sources
The access point can receive power from an external power module or from inline power using the
Ethernet cable. The access point supports the IEEE 802.3af inline power standard and Cisco CDP Power
Negotiation. Using inline power, you do not need to run a power cord to the access point because power
is supplied over the Ethernet cable.
Warning This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source. Statement 353
The access point supports the following power sources:
• Power module
• Inline power:
– Cisco Aironet 1250 Series Power Injector ( (AIR-PWRINJ3 or AIR-PWRINJ-FIB)
– An inline power capable switch, such as the Cisco Catalyst 3550 PWR XL, 3560-48PS,
3570-48PS, 4500 with 802.3AF PoE module, or the 6500 with 802.3AF PoE module
