Connecting Power; Power Over Ethernet (Poe) From The Lan; Power Over Ethernet From A Poe Injector - 3Com AirConnect 9550 Quick Start Manual

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.
Access Point

Power over Ethernet from a PoE Injector

To power the AP using a PoE injector or midspan (not included), follow these steps:
1
Connect 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 3CNJPSE-GIG
2
Connect a LAN cable from the Ethernet port on the AP to the other LAN port on the PoE
injector.
3
Plug the PoE injector into a properly grounded electric outlet. See the illustration.
