5. Hardware Installation

5.1  Before Installation

The POE-E304 is installed between the PSE (Power Source Equipment) 
and the PD (powered device); it is powered by PSE and forwards the 
Ethernet data and remaining POE power or an external power supply 
to the PD and it can be installed easily by just plug and play without 
affecting the data transmission performance.

Note

1. 

When the PoE-in-use LED turns steady orange, 
it means the Gigabit PoE OUT is supplying power 
successfully from PSE.

2. If the PoE-in-use LED is not lit, please check the 

remote PSE or the cable connecting to a PC or a 
network device to see if the cable is correct.

Never connect any 

non-standard

 POE PSE to the Gigabit 

PoE Extender; it will damage the device permanently.

5.3  Connecting POE-E304 to Powered Device (PD)

Step 1:

 Connect the additional Cat5e/6 cable that will be used to 

connect to the remote 

Powered Device (PD)

 to the 

“PoE 

Out”

 port of the Gigabit PoE Extender.

Step 2:

 The 

"PoE Out"

 port is also the power injector which transmits 

DC voltage to the Cat5e/6 cable and transfer data and power 
simultaneously between the PSE and PD.

Note

1. To provide you with better PoE power and data 

extension quality, we strongly recommend that you use 

“Solid UTP Cable”

 when installing the POE-304.

2. The POE-E304 can be installed with a third-party device 

if the device complies with IEEE 802.3at/af standard.

5.2  Connecting POE-E304 to PSE

This section describes how to install Gigabit PoE Extender and make 
connection to it. Please read the following topics and perform the 
procedures in the order being presented.
There are 4 RJ45 ports in the Gigabit PoE Extender, of which the 

“PoE 

IN”

 port functions as 

"PoE (Data and Power) input"

 and the four 

”PoE Out” 

ports function as 

"PoE (Data and Power) output"

.

Step 1:

  Connect a standard Cat5e/6 UTP cable from 

power source 

equipment (PSE)

, such as PoE switch, PoE injector hub and 

single port PoE injector, to the 

“PoE IN”

 port of the Gigabit 

PoE Extender.

Step 2:

  The PSE delivers both Ethernet data and PoE power over UTP 

cable to the Gigabit PoE Extender.

Step 3:

  Once the Gigabit PoE Extender detects the existence of an 

IEEE 802.3at/af device, the 

“PoE-in-Use”

 LED indicator will 

be lit steadily, showing it is providing powerr.

Note

1. If the connected device is not fully complying with IEEE 

802.3af/at standard or in-line power device, the PoE-in-
Use LED indicator of the Gigabit PoE Extender will not 
be lit steadily.

2. According to IEEE 802.3af/at standard, the Gigabit 

PoE Extender will not inject power to the cable if not 
connected to a standard IEEE 802.3af/at device.

5.4  PoE Power Distribution

The POE-E304 can obtain a maximum of 60-watt PoE power from Ultra 
PoE input port and supplies a maximum of 55-watt PoE power budget 
to four PoE output ports, extending both the reach of 

Gigabit Ethernet

 and

same time.

Note

1. 

The PoE Output Budget means the 4-port PD 
aggregated power output. The aggregated power 
consumption will be below 55 watts if with ultra PoE 
PSE.

2. If the PoE output, whose power source is 

IEEE 

802.3at PoE+

, is more than 25 watts, the device will 

be shut down.
