5. Connecting Power and the Network

The sensor connects to your network through its Ethernet port. This is also how the unit receives power. The sensor can be powered by the following methods:

•By Power Over Ethernet (PoE) supplied through the LAN by a 802.3af PoE compliant device such as a switch or hub.

•By PoE supplied by an optional 3Com PoE injector (not included). 3Com PoE injectors include the 3CNJPSE and 3CNJPSE24 midspan supplies.

Power Over Ethernet (PoE) from the LAN

To power the sensor using PoE provided by a switch or other 802.3af compliant device, simply plug the network cable from the device into the sensor’s Ethernet port.

Power Over Ethernet from a PoE Injector

To power the sensor using a 3Com PoE Injector (available separately), do the following:

1Connect the LAN cable from the switch or hub to the Hub/Switch port on the 3Com PoE Injector (available separately).

2Next connect a LAN cable from the Ethernet port on the sensor to the other port on the PoE injector.

3Plug the PoE Injector into a properly grounded electric outlet.
