1.2 About the Power over Ethernet Injector
The POE-152 is an IEEE 802.3af Power over Ethernet Injector that provides DC 48V over Ethernet cables. The POE-152
IEEE 802.3af Power over Ethernet Injector inserts DC Voltage into Cat.5 cable, allowing the cable between the Injector
(POE-152) and Splitter (POE-152S-5V/12V) to transfer data and power simultaneously. The maximum distance between
the Injector (POE-152) and Splitter (POE-152S-5V/12V) is 100 meters. With POE-152 being installed, it combines the
Ethernet digital data with power over the twisted pair cables as an IEEE 802.3af Power over Ethernet Injector. And the
IEEE 802.3af Power over Ethernet splitter shall separate the digital data and the power into two outputs.
Unlike existing Power over Ethernet Injector, except the 10/100Mbps Fast Ethernet connection ability, the POE-152 also
provide 1000Mbps Gigabit Ethernet connection ability.
With IEEE 802.3af Power over Ethernet devices being installed, the system administrator only has to use a single RJ-45
Ethernet cable to carry both power and data to each device. Besides, to connect through POE-152 and
POE-152S-5V/12V, you could also have benefits including cost saving, easy for networking planning and higher reli-
ability. What’s more, upon any IEEE 802.3af devices being installed, the POE-152 or together with POE-152S-5V/12V
can make the connection while migrating or splitting the power and the Ethernet digital packets, such as connecting the
POE-152 to an IEEE 802.3af complied devices, AP or IP phone.

2. HARDWARE INSTALLATION
This product provides three different running speeds – 10Mbps, 100Mbps, 1000Mbps in the same device and auto-
matically distinguishes the speed of incoming connection.
This section describes the hardware features of POE-152. Before connecting any network device to the POE-152, read
this chapter carefully.
2.1 Before Installation
Before your installation, it is recommended to check your network environment. If there is any IEEE 802.3af devices need
to power on, the POE-152 can provide you a way to supply power for this Ethernet device conveniently and easily. The
POE-152 equips with an AC-DC adapter with DC 48V input and injects, this DC power into the pin of the twisted pair cable
(pair 1, 2 and pair 3, 6 for Fast Ethernet) and (pair 4, 5 and pair 7, 8 for Gigabit Ethernet).
If there is very difficult to find a power socket for AC-DC Adapter of your non-IEEE 802.3af networked device, the POE-152
and POE-152S can provide you a way to supply DC power for this Ethernet device conveniently and easily.
The10/100/1000Mbps speed duplex mode from Ethernet port of POE-152 depends on which Ethernet device attached.
@Notice:
The POE-152 and POE-152S can be installed in pair. However, the use of third-party device is allowed if the device
complied with IEEE 802.3af standard.

2.2 POE-152, the Injector installation
1. Connect a standard network cable from Switch/workstation to “Ethernet” port of POE-152.
2. Connect the long cable that will be used to connect to the remote device to the port “Ethernet + DC”. The screen in
Figure 1 appears.
3. Connect the AC adapter to “DC 48V” of POE-152. The power LED will be steady on.
Figure 1: the Injector installation
2.3 POE-152 and POE-152S, the IEEE 802.3af Injector and Splitter installation
1. Connect a standard network cable from “Ethernet+DC” of POE-152 to “Ethernet+DC” of POE-152S. The POE LED of
POE-152 / POE-152S will light on continuance. The screen in Figure 2 appears.

@Notice:
1. According to IEEE 802.3af standard, the POE-152 will not inject power to the cable if not connecting to
IEEE 802.3af devices.
2. Please ensure the output voltage is correct before applying power to remote device.
2.4 Connect with IEEE 802.3af devices
Due to the capability of IEEE 802.3af standard, the POE-152 can directly connect with any IEEE 802.3af end-nodes like
wireless access point, VoIP phones and Internet camera where support IEEE 802.3af In-line Power over Ethernet port.
The screen in Figure 4 appears.
Figure 4: Connection to IEEE 802.3af device
Once POE-152 detects the existence of an IEEE 802.3af device, the LED indicator will be steady, ON to shows it is
providing power.
@Notice:
If the connected device is not fully complying with IEEE 802.3af standard or in-line power device, the LED indicator of
POE-152 will not be steady on.

3.TROUBLESHOOTING
This chapter contains information to help you solve issues. If the POE-152 is not functioning properly, make sure the
POE-152 was set up according to instructions in this manual.
The PoE LED is not lit
Solution:
Check the cable connection between POE-152 and IEEE 802.3af device.
Why I connect my PoE device to POE-152 and it cannot power on?
Solution:
1. Please check the cable type of the connection from POE-152 to the other end. The cable should
be an 8-wire UTP, Category 5/5e/6, EIA568 cable within 100 meters. A cable with only 4-wire,
short loop or over 100 meters, all will affect the power supply.
2. Please check and assure the device that fully complied with IEEE 802.3af standard.
10/100/1000Base-T port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to
change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
