Power over Ethernet (PoE)
The SPOEB10xx-1xx media converter transmits electrical power, along with
data, to remote devices over standard twisted-pair cable in an Ethernet network.
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 10BASE-T and 100BASE-TX
device configurations; therefore, Mode B requires a 4-pair cable.
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.

LED Description
PWR Green: Power ON
Fiber LACT Green: ON = Link, Blinking = activity
Fiber DPX Green: ON = Full, OFF = Half
TP* LACT Green: ON = Link, Blinking = activity
TP SPD Green: ON = 100Mb/s, OFF = 10Mb/s
TP DPX Green: ON = Full, OFF = Half, Blinking = collision
TP ON (PSE) Green: ON = Enabled, OFF = Disable
TP ERR (PSE) Yellow: OFF = no problems detected
Faults:
• Yellow: ON solid = main power is over or under voltage
• Blink: 1 times per sec - no signature detected
• Blink: 2 times per sec - overload while applying power
• Blink: 3 times per sec - short circuit detected
• Blink: 4 times per sec - multiple problems detected
* TP means twisted pair.
