4. Connecting Power
This section describes how to power the AP in either of these ways:
•By Power Over Ethernet (PoE) supplied over the LAN by an 802.3af PoE compliant device such as a switch.
•By PoE supplied by a PoE injector or midspan (not included with the AP).
Power over Ethernet (PoE) from the LAN
To power the AP using PoE provided by a switch or other 802.3af compliant device, plug the network cable from the device into the AP’s Ethernet port.

PoE Switch
Power over Ethernet from a PoE Injector
To power the AP using a PoE injector or midspan (not included), follow these steps:
1Connect the LAN cable from a switch to the Switch port on the PoE injector. 3Com recommends that you use a Gigabit PoE injector such as
2Connect a LAN cable from the Ethernet port on the AP to the other LAN port on the PoE injector.
3Plug the PoE injector into a properly grounded electric outlet. See the illustration.
