4.1.1 Functions
Data Transmission
10/100Base-T(X) Ethernet port is equipped with RJ45 connector. The port is self-adaptive. It can
automatically configure itself to work in 10M or 100M state, full or half duplex mode. The port can
also adapt to MDI or MDI-X connection automatically. You can connect the port to a terminal or
network device with a straight-through or cross-over cable.
POE
The 10/100Base-T(X) Ethernet ports of KIEN2204S support 802.3at POE output. Serving as the
Power Sourcing Equipment (PSE), KIEN2204S can provide power supply for PDs through
10/100Base-T(X) Ethernet ports. Each POE port provides 30W feed (44-57VDC).
1. POE Definition
POE indicates that the device can provide power supply for PDs through Ethernet ports. The
device allows a maximum distance of 100m for power supply.
2. POE Power Supply
The device supports data wires (1, 2, 3, and 6) and free wires (4, 5, 7, and 8) to be used for PD
power supply at the same time.
