9.3.2 Ethernet connection
The device can be powered by the following ways:
• Using the connector A
• Using the PoE (Power over Ethernet) function, which is integrated into
the Ethernet connection on connector B.
To power the unit via PoE, a switch that supports PoE is needed.
PoE comes into two standards:
• Type A: The PoE switch powers the device via Pair 2 (Pin 1 and Pin 2)
and Pair 3 (Pin 3 and Pin 6)
• Type B: The PoE switch powers the device via Pair 1 (Pin 4 and Pin 5)
and Pair4 (Pin 7 and Pin 8)
This device supports both types.
