Ethernet (Poe) Ports - Cisco Aironet 1550 Series Hardware Installation Manual

Chapter 1 Overview

Ethernet (PoE) Ports

The access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The access
point PoE-in port uses an RJ-45 connector (with a liquid tight adapter) to link the access point to the
10/100/1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to
optionally supply inline 56-VDC power from the power injector.
When a 1552E or 1552H access point is powered by PoE, the PoE-Out port is not active.
Note
The access point PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector to provide LAN
connectivity and IEEE 802.3af power to a single peripheral customer device, such as a camera or sensor
gateway. The PoE-out port should not be connected to a switch or hub. The Ethernet MAC addresses are
printed on the bottom of the access point under the LEDs.
The PoE-out port is disabled when the access point is powered by the power injector.
Note
Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to
match the cable connections.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access
point senses the Ethernet and power signals and automatically switches internal circuitry to match the
cable connections.
To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power
Caution
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause
the access point to malfunction and cause possible over-current conditions at the power source.
Fiber Option
Warning Class 1 laser product. Statement 1008
The factory-orderable fiber option provides a fiber input and output capability. Fiber data is transmitted
and received over a single-strand fiber cable, which is connected to the access point using these SFP
modules:
