2.6 Power Injector and Power Tap Systems

An AP-5131 or AP-5181 access point can receive power via an Ethernet cable connected to the access
point's LAN port (using 802.3af). When users purchase a WLAN solution, they often need to place
access points 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 and Power Tap solutions merge power and Ethernet into one cable, reducing the
burden of installation and allow optimal access point placement in respect to the intended radio
coverage area.
Both the Power Injector and Power Tap are integrated AC-DC converters requiring 110-220 VAC power
to combine low-voltage DC with Ethernet data in a single cable connecting to the access point. The
access point can only use a Power Injector or Power Tap when connecting the unit to the access
point's LAN port. The Power Injector (Part No. AP-PSBIAS-1P2-AFR) is included in certain AP-5131
kits. The AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R) is ordered separately and is intended
for AP-5181 outdoor deployments.
NOTE Though an AP-5181 can use the Power Injector solution (Part No. AP-
recommended 48-Volt Power Supply (Part No. 50-14000-243R).
Motorola recommends the AP-PSBIAS-5181-01R Power Tap for use an
AP-5181 and its intended outdoor deployment.
PSBIAS-1P2-AFR), Motorola recommends using the AP-5181 Power Tap
(Part No. AP-PSBIAS-5181-01R) designed especially for outdoor
deployments.
