Step 10: Power on the Unit
The unit is equipped with a Power-over-Ethernet (PoE) module. Using PoE, you
can provide electricity and wired connectivity to the unit over a single Category
5 cable. Although the power injector that is supplied with the unit is 802.3af-
compatible, standard 802.3af-compliant power modules will not properly power
the units. Always use the supplied power injector.
The PoE integrated module provides –48 VDC over a standard CAT5
Ethernet cable.
Maximum power supplied to the unit is 20 Watts (when the unit is heating
or cooling); the units typically draw less than 7.5 Watts.
The unit only accepts power on the “extra pairs”, not on the data pairs
according the conguration for “midshipman” power injection, see the IEEE
802.3af standard.
Once you have connected the power injector to the Ethernet cabling and
plugged the power injector cord into an AC outlet, the unit is powered on.
There is no ON/OFF switch on the unit. To remove power, unplug the AC cord
from the AC outlet or disconnect the RJ45 connector from the “Data and Power
Out” port on the power injector.
