Chapter 1 Overview
Hardware Features
LEDs
The access point has three LEDs (see Figure 1-1) to indicate Ethernet activity, radio activity, and status
indications (refer to the “Checking the Autonomous Access Point LEDs” section on page 3-2 or the
“Checking the Lightweight Access Point LEDs” section on page 4-3 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.
Ethernet Port
The Ethernet port is located on the bottom of the unit in the access point connector area (see Figure 1-3).
The auto-sensing Ethernet port accepts an RJ-45 connector, linking the access point to your 10BASE-T,
100BASE-T, or 1000BASE-T Ethernet LAN. The Ethernet interface supports automatic media
dependent interface crossover (MDIX) detection, which automatically senses cable type
(straight-through or crossover) and adjusts the internal connections appropriately. Also the interface
automatically senses the data rate being received over the connected cable.
The access point can receive power through the Ethernet cable from a 1250 series power injector. The
Ethernet MAC address is printed on the label on the bottom of the access point.
