Powering the Access Point
The Ethernet cable from the power injector to the access point (PoE In port) must be at least 10 ft (3.1
Note
m) in length.
The PoE Out port is disabled when the access point is powered by the power injector.
Note
When your access point is powered by an optional power injector, follow these steps to complete the
installation:
Before applying PoE to the access point, ensure that the access point is grounded (see the
Step 1
the Access Point (all models)" section on page
Review
Step 2
Note
Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
Step 3
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Warning
Use only the 1500 power injector (AIR-PWRINJ1500-2=) for the access point. This power injector is
designed to meet the power requirements of the access point and is a listed Class 2 limited power source
(LPS).
The installer is responsible for ensuring that powering the access point from this type of power injector
Note
is allowed by local and/or national safety and telecommunications equipment standards.
Tip
Ensure that the antennas are connected and that a ground is attached to the access point before you apply

It is recommended to install the injector in its own IP67 enclosure such as a Hoffman box, since
the PoE injector is not weather proof.
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.
When a 1552H access point is powered by PoE, the PoE Out port is not active.
