1 1. Introduction Power-over-Ethernet (PoE) eliminates the need to run 110/220 VAC power to other devices on a wired LAN. Using Power-over-Ether net system installers need to run only a single CAT5 Ethernet cable that carries both power and data to each de vice.
2 Remote power feeding up to 100 mete rs and for IEEE802.3 10Base-T, IEEE 802.3u 100Base-TX standard Centralized power distribution for PoE powered Device (PD) High safety short circuit protec tion to prevent cable short Supports IEEE 802.
3 2. Hardware Description This Section mainly describes the hardwar e of the POH-0850TX, and gives a physical and functional overview. P h y s i c a l D i m e n s i o n The 8-port Power over Ethernet .
4 Figure 2-2. LED indicators LED Status Color Description On Green Power is transmitting to the device Power Forwarding Off -- Power is not transmitting to the device On Orange Device is overload or short. Off -- D evice attached. Power Off Blinking Orange Detecting the device Table 2-1.
5 side of power cord connects to the power outlet. The in ternal power supply of the Switch works with voltage range of AC in the 100-240VAC, frequency 50~60Hz.
6 3. Software Utility Installation Berfore you star to remote configuring PD, please intsall the sof tware utility. Through the software utility, you can easily to cont roll the PD that connect with PoE and view the PD parameter informations . The software utility provides GUI interface and user can easily to start with it.
7 Figure 3-2 6. When installation finishes, click “O K” button to finish. See Figure 3-3. Figure 3-3 7. To run the software utility, go to “ Star ” “ Program ” “ Power Over Ethernet ”.
8 8. If you want to remove the software utility, go to “ Star ” “ Control Panel ” “ Remove/ Add application ” “ Power Over Ethernet ”.
9 4. GUI Management C o n n e c t i n g t o P o E Connecting the PoE with PC through the cons ole port. Then, connect the PD (Powered Device) to the port of PoE. Run the so ftware utility and select the COM port form Serial Link Setup function. You will see the main utility interface as figure 4-1.
10 device current configuration to the ut ility system and enable auto refresh function. Port Specific Control: each port specific function control and relate parameters display. Parametric Information: port parameters information di splay. System Setup & Control Master Enable: Enable/Disable the control of GUI.
11 System Information Chip Version: display the system chipset version and revision information. Firmware Version: display the system firmware version. Utility Version: display the system utility version Total Port Power (W): total of all the port power that the system provided to PD.
12 Figure 4-4 Device Setting interface.
13 Port Specific Control Port Enable: enabling the port. This function is co-responding with “Master Enable” function. Bypass Detection: bypass the detection function. Normally the system will try to detect the 25k Ω resistor in an 802.3af compliant PD device.
14 The LED indicator will change depends on the PD status. Green: It represents PD is connecting with the POE hub system and working normally. Yellow: It represents there is no PD connecting with the port. RED: It represents PD’s power request is over the system support limit or the cable is short.
15 Parametric Information Discovery R (ohms): display resistance value. Port Current (mA): display current value. Port Voltage (V): display voltage value. Port Power (W): display watt value. Class Current (mA): display class current value.
16 5. Technical Specification St andard IEEE802.3af Power over Ethernet Connector Data in: 8 x RJ-45, Data pin 1,2,3,6 Data and power out: 8 x RJ-45. Data pin 1,2,3,6 Power pin (V+): 4, 5, Power pin (.
17 Parametric information It will show current PD parameters which include Discover-resistor detected value, current, voltage, power consumption, classification current and determined class LED System.
18 6. Appendix Console Port Pin Assignments The female DB-9 serial port on the POE hub front panel is used to connect to the switch for out-of-band console configuration. The web inte rface configuration program can be accessed from PC running the syst em utility program.
