Board Layout

Interceptor PoE Board Layout Reference

Connector Reference:

J6 - Eight port RJ-45 switch
U13, U14 - Ethernet magnetics
J2 - FFC (40 pos) connection to carrier board
J1 - PoE power input (48V DC)
H1, H2, H3 - Mounting holes

Connectors

J1 - Power Input (Terminal Block)

48V DC power input from VOITA converter.

Terminal	Signal
+	+48V DC
-	Ground (GND)

Warning

Ensure correct polarity when connecting the VOITA converter. Reverse polarity may damage the board.

J2 - FFC Connector (40-pin)

Connection to Interceptor Carrier Board (J9 or J10).

Parameter	Value
Type	40-pin FFC/FPC
Pitch	0.5mm
Orientation	Contacts up, blue reinforcement tape down, printing visible on top

Important

Insert the FFC cable evenly and deep. Most of each contact should be inside the connector, though the back portion of each contact may be partially visible. What matters is that all contacts are inserted to the same depth—if one side is deeper than the other, reseat the cable. Even and deep is key. Locked in.

If you do not have it locked in and move the cable while powered on, it can burn out the cable and make it useless.

J6 - Ethernet Ports (8-port)

Eight RJ-45 ports with PoE injection.

Port	Interface (Board 1)	Interface (Board 2)
0	poe0	poe8
1	poe1	poe9
2	poe2	poe10
3	poe3	poe11
4	poe4	poe12
5	poe5	poe13
6	poe6	poe14
7	poe7	poe15

The interface name depends on which carrier board connector the PoE board is attached to:

J9 → Board 1: poe0 through poe7
J10 → Board 2: poe8 through poe15

Dual Board Port Numbering

When using two PoE boards:

Board	Carrier Connector	Ports	Interfaces
Board 1	J9	0-7	poe0-poe7
Board 2	J10	8-15	poe8-poe15

Port Layout

The board is designed to stack alongside or above the carrier board:
