Cable Modem (Poc); Ethernet (Poe) Ports - Cisco Aironet 1550 Installation Manual

Hardware Features
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Warning
Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which can cause the
access point to malfunction and cause over-current conditions at the power source.
The 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.
Caution
Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is
powering the access point should be provided with ground fault protection (GFCI), as required by Article
210 of the National Electrical Code (NEC).
In the cable configuration, the cable modem is activated only when the access point is powered by POC
Note
or external 12 VDC power. When using only PoE power, the cable modem is deactivated.
The following AC power cord options are available:
•

Cable Modem (POC)

The access point POC cable modem configuration contains an internal cable modem for connection to
the cable network from the pole-mounted cable lines. The access point can be powered using the 40-to
90-VAC (quasi-square wave AC) power provided by the cable network.
The cable modem supports these main features:
•
•

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.
