Chapter 2 Installing the Access Point
Connecting the Ethernet and Power Cables

Connecting to an Ethernet Network with an Inline Power Source

Follow these steps to connect the access point to the Ethernet LAN when you have an inline power
source:
Step 1 Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point.
Step 2 Connect the other end of the Ethernet cable to one of the following:
A switch with inline power, such as a Cisco Catalyst 3500XL, 3550, 4000, or 6500 switch.
An inline power switch panel, such as a Cisco Catalyst Inline Power Patch Panel.
The end of a Cisco Aironet power injector labeled To AP/Bridge. Connect the other end labeled To
Network to the 10/100 Ethernet LAN.
Caution The Cisco Aironet Power Injector (Cisco AIR-PWRINJ3= or Cisco AIR-PWRINJ-FIB= ) is designed for
use with 1100 or 1200 series access points. Using the power injector with other Ethernet-ready devices
can damage the equipment.
Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a
building’s environmental air space; no other power injectors or power modules have been tested to UL 2043
and they should not be placed in a building’s environmental air space, such as above suspended ceilings.
Note If you use a power injector to power the access point, you must use the power supply included with your
access point and the Cisco Aironet Power Injector specified for the access point.

Connecting to an Ethernet Network with Local Power

Follow these steps to connect the access point to an Ethernet LAN when you are using a local power
source:
Step 1 Connect the Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on the access point.
Step 2 Plug the other end of the Ethernet cable into an unpowered Ethernet port on your network.
Step 3 Connect the power modules output connector to the 48-VDC power port labeled 48VDC on the access
point.
Step 4 Plug the other end of the power module into an approved 100- to 240-VAC outlet.
