2.5.2 AP-5181 Power Options
The power options for the AP-5181 include:
• Power Injector (Part No. AP-PSBIAS-1P2-AFR)
• Power Tap (Part No. AP-PSBIAS-5181-01R)
• Any standard 802.3af compliant device.
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 the 802.3af standard). 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.
CAUTION An AP-5181 model access point cannot use the AP-5131
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.
NOTE Though an AP-5181 can use the standard Power Injector solution (Part
No. AP-PSBIAS-1P2-AFR), Motorola recommends using the AP-5181
Power Tap (Part No. AP-PSBIAS-5181-01R) designed especially for
outdoor deployments.
