2.2 POE-400 and POE-152S, the IEEE 
802.3af Injector / Splitter and Equipment 
Installation
For the places hard to nd the power inlet, the POE-400 
provide the easiest way to power your Ethernet devices 
such as PLANET IEEE 802.3af Power over Ethernet Splitter 
(POE-152S) with Internet Camera (ICA-M220) or Wireless 
Access Point (WNAP-3000PE) installed in the small ofce.
To control the power system of your networking devices, the 
POE-400 can directly co-work with PLANET ICA-HM230 and 
POE IP Phone VIP-351PT to build VoIP telephony network in 
the ofce. Besides, the POE-400 can be directly deployed to 
connect the third party IEEE 802.3af devices like Cisco AP 
and POE switches installed 100 meters away.

1.2 About the Power over Ethernet Injector 
Hub
The PLANET POE-400 is a 4-Port IEEE 802.3af Power over 
Ethernet injector hub complied with IEEE 802.3, IEEE 
802.3u and IEEE 802.3af standards. Equipped with 4 
10/100Base-TX Fast Ethernet ports, the POE-400 supports 
full 48V DC power for any remote IEEE 802.3af powered 
device (PD) like Wireless LAN Access Point, IP Phone, and 
LAN Camera. Supporting power supply of 70 Watts, POE-
400 provides sufcient power to the 4 remote devices.
There are 8 RJ-45 STP ports on POE-400. Half of the ports 
on right panel function as "Data" and the other half on left 
panel function as "Data and Power". Each of the "Data  
and Power" port as an injector which inserts DC Voltage 
into the CAT 5 cable allowing the cable between the Injector 
and Splitter to transfer data and power simultaneously.

2. Hardware Installation
This product provides two different running speeds – 
10Mbps, 100Mbps, in the same device and automatically 
distinguishes the speed of incoming connection.
This section describes the hardware features of POE-400. 
Before connecting any network device to the POE-400, 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-400 can provide you a way 
to supply power for this Ethernet device conveniently and 
easily. The POE-400 equips with an AC-DC adapter with 
DC 48V input and injects this DC power into the pin of the 
twisted pair cable (pair 4, 5 and pair 7, 8). 
If there is very difcult to nd a power socket for AC-DC 
Adapter of your non-IEEE 802.3af networked device, the 
POE-400 and POE-152S can provide you a way to supply 
DC power for this Ethernet device conveniently and easily. 
The 10Mbps or 100Mbps speed, duplex mode from Data 
port of POE-400 depends on which Ethernet device 
attached.

Figure 1: Connection architecture over POE-400
1. According to IEEE 802.3af standard, the 
POE-400 will not inject power to the cable 
if not connecting to IEEE 802.3af devices.
2. Due to the capability of IEEE 802.3af 
standard, the POE-400 can directly connect 
with any IEEE 802.3af end-nodes.

This chapter contains information to help you solve 
problems. If the PoE Injector Hub is not functioning 
properly, make sure the PoE Injector Hub was set up 
according to instructions in this manual.
How to let my non IEEE 802.3af network devices 
can work with POE-400?
Solution:
You can use PLANET Power over Ethernet Splitter, such as 
PLANET POE-152S to work as a power transformer between 
POE-400 and non IEEE 802.3af devices. Two types of POE152S are available for different voltage, 5V DC and 12V DC.
The PoE LED is not lit
Solution:
Check the cable connection between POE-400 and IEEE 
802.3af device.

Why I connect my PoE device to POE-400 and it 
cannot power on? 
Solution:
1. Please check the cable type of the connection from POE400 to the other end. The cable should be an 8-wire UTP, 
Category 5/5e, 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.

The standard RJ-45 receptacle/connector
There are 8 wires on a standard UTP/STP cable and each 
wire is color-coded. The following shows the pin allocation 
and color of straight cable and crossover cable connection:
Figure A-1: Straight-Through and Crossover Cable
Please make sure your connected cables are with same pin 
assignment and color as above picture before deploying the 
cables into your network.
Energy Saving Note of the Device 
This power required device does not support Standby mode 
operation. 
For energy saving, please remove the power cable to 
disconnect the device from the power circuit.
Without removing power cable, the device will still 
consuming power from the power source. In the view of 
Saving the Energy and reduce the unnecessary power 
consuming, it is strongly suggested to remove the power 
connection for the device if this device is not intended to be 
active.
