Cisco Aironet 1552 Series for Hazardous Locations Installation Guide
Chapter 3 Installing the 1552 Series Access Points in Hazardous Locations
Powering the Access Point
Note The Ethernet cable from the power injector to the access point (PoE In port) must be at least 10 ft (3.1
m) in length.
Note
The PoE Out port is disabled when the access point is powered by the power injector.
When your access point is powered by an optional 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 “Grounding
the Access Point (all models)” section on page 3-60 ).
Step 2
Review Chapter 2, “Pole Mount Installation” to identify the components needed for the installation.
Note
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.
Step 3
Connect a CAT5e or better Ethernet cable from your wired LAN network to the power injector.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
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).
Note 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.
Tip 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.
Step 4 Ensure that the antennas are connected and that a ground is attached to the access point 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 (see
Figure 3-20 ).
Step 6 Connect the Ethernet cable to the access point PoE In port (see “Connecting an Ethernet Cable to the
Access Point (all models)” section on page 3-73 ).
Note When a 1552H access point is powered by PoE, the PoE Out port is not active.
