Power Injector System - Motorola AP7131 Installation Manual

Installation Guide

2.3.2 Power Injector System

The Access Point can receive power via an Ethernet cable connected to the GE1/POE (LAN) port.
When users purchase a WLAN solution, they often need to place Access Point in obscure locations. In the past, a
dedicated power source was required for each Access Point in addition to the Ethernet infrastructure. This often
required an electrical contractor to install power drops at each Access Point location. The Power Injector merges
power and Ethernet into one cable, reducing the burden of installation and allowing optimal Access Point
placement in respect to the intended coverage area.
The Power Injector (Part No. AP-PSBIAS-1P3-AFR) is a high power POE Injector delivering up to 30 watts. The
Access Point can only use a Power Injector when connecting the unit to the Access Point's GE1/POE port. The Power
Injector is separately ordered and not shipped with an existing AP SKU.
An AP7131 and AP7131N can also be used with the 3af power injector (AP-PSBIAS-1P2-AFR). However, AP
functionality is limited when powered by an AP-PSBIAS-1P2-AFR, since the AP has Ethernet connectivity limited to
only the GE1 port.
The Access Point Power Supply (Part No. 50-14000-247R) is not included with the Access Point and is orderable
separately as an accessory. If the Access Point is provided both POE power over the GE1/POE connection, as well
as the 50-14000-247R power supply concurrently, the Access Point will source power from the 50-14000-247R
supply only. Disconnecting AC power from the 50-14000-247R, causes the Access Point to re-boot before sourcing
power from the POE power injector. If the Access Point is operating using injector supplied power, the Access Point
will not automatically reboot if an AC adapter is connected. The Access Point continues to operate with power
supplied from the AC adapter without change to the Access Point's operating configuration. If using AC adapter
supplied power and a change to the Access Point's operating configuration is warranted (for example, if needing
to access the GE2 port), the Access Point needs to be manually rebooted by the customer.
CAUTION
The Access Point supports any standards-based compliant power
source. However, using the wrong solution (including a POE system
used on a legacy Access Point could either limit functionality or
severely damage the Access Point and void the product warranty.
