1.

Connect an RJ-45 Ethernet cable between the network data supply (host) and the Power 
Injector’s Data In or the Power Tap’s DATA IN connector.

2.

Connect an RJ-45 Ethernet cable between the Power Injector’s Data & Power Out 
connector or the Power Tap’s DATA/PWR OUT connector and the access point’s LAN port.

Ensure the cable length from the Ethernet source (host) to the Power Tap (or Power Injector) 
and access point does not exceed 100 meters (333 ft). Neither the Power Tap or Power 
Injector has an On/Off switch. Each receives power as soon as AC power is applied. 

3.

For Power Tap installations, have a certified electrician open the Power Tap enclosure, feed 
the power cable through the unit’s LINE AC connector, secure the power cable to the unit’s 
three screw termination block and tighten the unit’s LINE AC clamp (by hand) to ensure the 
power cable cannot be pulled from the unit and is protected from the elements.

4.

For Power Tap installations, attach a ground cable between the EARTH GROUND 
connector (on the back of the unit) to a suitable earth ground connection as defined by your 
local electrical code.

5.

Verify all cable connections are complete before supplying power to the access point. 

The Power Injector demonstrates the following LED behavior under normal and/or problematic 
operating conditions: 

CAUTION Ensure AC power is supplied to the Power Injector or Power Tap (for 

AP-5181 installations) using an AC cable with an appropriate ground 
connection approved for the country of operation.

CAUTION Cabling the Power Injector to the access point’s WAN port renders the 

access point non-operational. Only use a Power Injector or Power Tap 
with the access point’s LAN port.

The AP-5181 Power Tap (Part No. AP-PSBIAS-5181-01R) does not have 
LED indicators.
