Introduction
Thank you for purchasing MiLAN Technology’s EmPoweredTM Series 8-port Power over
Ethernet Injector Hub. Power-over-Ethernet (PoE) eliminates the need to run 110/220
VAC power to other devices on a wired LAN. Using Power-over-Ethernet, system
installers need to run only a single CAT5 Ethernet cable that carries both power and data
to each device. This allows greater flexibility in locating network devices and significantly
decreases installation costs, in many cases.
There are two system components in PoE -- the Power Sourcing Equipment (PSE)
initiates the connection to the second component, the Powered Device (PD). The current
is transmitted over two of the four twisted pairs of wires in a Category-5 cable.
The MIL-L800i complies with the IEEE 802.3af standard and is completely compatible
with existing industry standard Ethernet switches and networked devices. Since the
Power Sourcing Equipment (PSE) tests whether a networked device is PoE-capable,
power is never transmitted unless a Powered Device (PD) is at other end of the cable. It
also continues to monitor the channel. If the Powered Device does not draw a minimum
current, because it has been unplugged or physically turned off, the PSE automatically
shuts down the power to that port. Optionally, the standard permits Powered Devices to
signal to the PSEs exactly how much power they need.

device
On Orange Device is overload or short.
Blinking Orange It is detecting the PD.
Power Off
Off -- No device attached.
Table 2-1. The Description of LED Indicators
RearPanel
The 3-pronged power plug, 2 Ventilation fan and on/off switching are located at the rear
panel of the 8 port Power over Ethernet Hub. The device will work with AC in the range
100-240V AC, 50-60Hz.

Figure 2-3 Rear panel of the 8 port Power over Ethernet Hub
PowerOn
Connect the power cord to the power socket on the rear panel of the Switch. The other
side of power cord connects to the power outlet. The internal power supply of the Switch
works with voltage range of AC in the 100-240VAC, frequency 50~60Hz. Check the
power indicator on the front panel to see if power is properly supplied.
NetworkApplication
The Power over Ethernet Hub can provides power to the PD that follow the IEEE 802.3af
standard in the network. It can solve the problem of position limitation. The network
device can be installed in more appropriate position for better performance. The
following figure is an example of network application for Power over Ethernet Hub.
[Note] When the Power over Ethernet Hub connects with the Cisco Aironet 350, please
use cross over cable for connection. For the other brands’ devices, please use
non-cross over cable.

GUI Management
ConnectingtoPoE
Connecting the PoE with PC through the console port. Then, connect the PD (Powered
Device) to the port of PoE. Run the software utility and select the COM port form Serial
Link Setup function. You will see the main utility interface as figure 4-1.
Figure 4-1. The GUI management interface
The GUI management is divided into three parts:
System Setup & Control: main system level parameters setup for the POE system.
System Information: display hardware version, firmware version, and utility
version.

11
Device Setting: you can save the device configuration to system, down load the
device current configuration to the utility system and enable auto refresh function.
Port Specific Control: each port specific function control and relate parameters
display.
Parametric Information: port parameters information display.
System Setup & Control
Calibrate System: when the system can’t do the port controlling, please remove the
PD device and enable this function to calibrate internal system.
PD Discovery R (ohms): set the PD resistor value range for the system detecting.
The default value range is 19000~26500. You can adjust the upper and lower limit
value when the system can’t detect the PD resistor in the default range. Please refer to
the “Discover R (ohms)” value in Parametric Information section to adjust the upper
and lower limit value. After you have adjusted the upper or lower limit value, please
unplug and then plug in the PD device.
Figure 4-2. System Setup & Control interface

12
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.
Figure 4-3. System Information interface

13
Device Setting
Enable Auto-Refresh: It allows the system auto refresh the system parameters.
The system auto refresh in every 2 seconds.
Load from Device : To get the last configuration value from device to the system
utility.
Save to Device : When you have configured the System Setup & Control and
Port Specific Control, please press Save to Device button to apply the new
configuration into the system.
Figure 4-4 Device Setting interface

14
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 25kΩresistor in an 802.3af compliant PD device. If the PD doesn’t follow
by IEEE 802.3af standard, you can enable this option to skip the detection on PD.
When you enable this function, the system will not perform the 25Ωresistor
detection for PD and directly transmit the power to PD. This function can be
cooperating with “PD discover R (ohms)” function in System setup & Control section
for non-standard compliant PD device.
[Note] after setting the Bypass Detection function, please unplug and then plug in
the PD device.
Bypass Classification: the system will skip the power classification and directly
transmit the power to PD when this function is enabling. Normally the system will try
to classify the 802.3af compliant PD device by checking the current class level. The
following table is a standard current classification level table.
Note: After setting the Bypass Classification function, please unplug and then plug in
the PD device.
Power Device

Table of Power Device Classification Levels

15
LED Status Indicators: current LED indicator display – green, yellow, and red. The
LED indicator will change depends on the PD status.
¾Green: It represents PD is connecting with the POE hub system and working
normally.
¾Yellow: It represents there is no PD connecting with the port.
¾RED: It represents PD’s power request is over the system support limit or the
cable is short.
Fault Status: display the PD error status message. There are three error status and
explain as following.
¾Null: It means there is no PD connected or the connected PD device status is
normal.
¾Overload: It means the current is over the PD current classification limited
(475mA @ 48V DC) that the situation happens over 50msec.
Mode Status: display the PD current operation mode status.
¾V sample or I sample: It means " Current sample or Voltage sample”. When
PD is detected and current is supplied, the POE hub will keep detecting and
sampling some current or voltage to ensure whether the PD still present on this
port. It is a IEEE 802.3af operating procedure.
¾R detect: When the port doesn’t connect with any PD, the POE hub will poll
each port and detects the resistor.
