Chapter2 Installing the Access Point

Connecting the Ethernet and Power Cables

Note Some older switches and patch panels might not provide enough power to operate the access point. At

power-up, if the access point is unable to determine that the power source can supply sufficient power,

the access point automatically deactivates both radios to prevent an over-current condition. The access

point Status LED turns amber and an error log entry is created (refer to the “Checking the Autonomous

Access Point LEDs” section on page3-2 or the “Checking the Lightweight Access Point L EDs” section

on page 4-3).

Connecting to an Ethernet Network with an Inline Power Source

Caution Be careful when handling the access point; the bottom plate might be hot.

Note If your access point is connected to in-line power, do not connect the power module to the access point.

Using two power sources on the access point might cause the access point to shut down to protect internal

components and might cause the switch to shut down the port to which the access point is connected. If

your access point shuts down, you must remove all power and reconnect only a single power source.

Follow these steps to connect the access point to the Ethernet LAN when you have an inline power

source:

Step1 Connect a Category 5 Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access

point (see Figure 2-13).

Figure2-13 Ethernet and Power Ports

Step2 Connect the other end of the Ethernet cable to one of the following:

•A switch with inline power (see the “Connecting the Ethernet and Power Cables” section on

page 2-20).

•The end of a Cisco Aironet power injector labeled To AP/Bridge. Connect the other end labeled To

Network to your 10/100 Ethernet LAN.
