Installation
Power over Ethernet (PoE)
The
There are two modes of transmitting 48VDC PoE as defined in IEEE 802.3af: Mode A uses pins 1&2, 3&6 to transmit data and power; Mode B uses pins 4&5, 7&8 to transmit power. These are the spare pairs in
To set A or B PoE Mode, do the following:
1.Remove the 4 screws and pull the cover off the media converter.
2.Locate the 3 header connects J2, J3, and J4.
2 Set jumpers 2, 3, and 4 to the same side, either (S or U). See diagram below.
