Installing the Access Point
Powering the Access Point
The 1540 series access points can be powered only through Power-over-Ethernet (PoE), using 802.3af
or 802.3at power, or UPoE, from in-line power injector or a suitably powered switch port. Power for full
operation is provided by 802.3af (or higher), and operates at 2x2:2 for both 2.4 GHz and 5 GHz radios.
The 1540 series access point supports the following power injectors:
•
•
•
•

Connecting a Power Injector
When your access point is powered by a power injector, follow these steps to complete the installation:
Step 1
Before applying PoE to the access point, ensure that the access point is grounded (see the
the Access Point" section on page
Step 2
See the
needed for the installation.
Step 3
Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
Note
Tip
Step 4
Ensure that the access point is grounded before you apply power to the access point.
Step 5
Connect a shielded outdoor-rated Ethernet (CAT5e or better) cable between the power injector and the
PoE-in connector of the access point.
Step 6
Connect the Ethernet cable to the access point PoE-In port. See
Access Point" section on page
For details on installing Ethernet, see
AIR-PWRINJ5 (provides 802.3af power)
AIR-PWRINJ6 (provides 802.3at power). This power injector can only be used in an indoor
environment. Therefore the cable from the injector must travel from the indoor location to the access
point mounted outdoor.

The installer is responsible for ensuring that powering the access point from this type of power
injector is allowed by local and/or national safety and telecommunications equipment standards.
To forward bridge traffic, add a switch between the power injector and controller. Refer to the
Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0 for more
information.
