Ethernet (Poe) Ports - Cisco Aironet 1550 Series Getting Started Manual

In the cable configuration, the cable modem is activated only when the access point is powered
Note
by POC or external 12 VDC power. When using only PoE power, the cable modem is
deactivated.
Three AC power cord options are available:
• 40-ft (12.2-m) power cord for installations in the US and Canada. One end of the power
terminated with an access point AC power connector and the other end is terminated with an
AC plug (AIR-CORD-R3P-40NA=).
• 40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is
terminated with an access point AC power connector and the other end is unterminated.
(AIR-CORD-R3P-40UE=).
• 4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada
(AIR-PWR-ST-LT-R3P=).

Ethernet (PoE) Ports

The access point supports an Ethernet uplink port (PoE-In) and a PoE out port (PoE-Out). The access
point Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to
the 10BASE-T, 100BASE-T, or 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 1552EU access point is powered by PoE, the PoE-Out port is not active.
Note
The access point PoE-Out Ethernet port uses an RJ-45 connector (with weatherproofing) to provide
LAN connectivity and IEEE 802.3af power to a 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 a label 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
The access point senses the Ethernet and power signals and automatically switches internal
