APPENDIX C: POWER OVER ETHERNET
APPENDIX C
Power over Ethernet
The BLK-IPE101 encoder supports Power over Ethernet (PoE) in conformance with the IEEE 802.3af
standard. IEEE 802.3af allows for two power options for Category 5 cables.
•
The PoE module signature and control circuit provides the PoE compatibility signature and power
classification required by the Power Sourcing Equipment (PSE) before applying up to 15 W power to
the port.
•
The high efficiency AC/DC converter operates over a wide input voltage range and provides a
regulated low ripple and low noise output. The AC/DC converter also has built-in overload and
short-circuit output protection.
C.1 PoE compatibility
With non Power Sourcing Equipment (PSE)
When it is connected with non PSE, use the power adaptor to provide power to the encoder.
With power adaptor
Connecting both PSE and power adaptor does not do any harm to the products. Disconnecting power
adaptor while it is operating does not stop operation. The product continues to work without rebooting.
C.2 Power classification
The PoE Power Class supported by the IP device is Class 0.
