PoE Mode:
PoE Mode Description
802.3bt
Lights to indicate the device is working in IEEE 802.3af/at/
bt PoE mode.
Force
Lights to indicate the device is working as 4-pair 60-watt 
force PoE PSE.
PoE Mode:
PoE Mode Description
Standard Fully conforms to the IEEE 802.3af/at/bt standard.
Legacy
The legacy detection is to identify the valid current 
signature of the PDs that do not fully follow the IEEE 
802.3af/at/bt standard. This protects against damage to 
the PDs as the right PoE mode is applied.
Force
If the output power of injector is less than 1 watt when it 
works in Legacy mode; after 20 seconds, the Force mode 
will be enabled.
When the Force mode is enabled, it will provide PD with 
max. 60W.
If the output power of injector is less than 1 watt when it 
works in Force mode; after 2 seconds, the Legacy mode 
will be enabled.

Note
1. After adjusting the DIP switch, the PoE port will stop 
and then work again.
2. Before connecting the Ethernet+DC port to network 
device, please make sure that it accepts PoE input to 
prevent damage.
5. Hardware Installation
The following section describes the hardware installation of the 
POE-171A series and POE-176-95. Before connecting any network 
device to it, please read this chapter carefully.
5.1  Before Installation
Before your installation, it is recommended to check your network 
environment. If there is any IEEE 802.3bt device that needs to be 
powered on and works normally, the POE-171A series/POE-176-95 
provides you with a way out to supply power to this Ethernet device 
conveniently and easily. The POE-171A series/POE-176-95 is equipped 
with a power adaptor which is 100-240V AC input and injects DC 
52~56V power into the pin of the twisted-pair cable (pair 1/2 [-], 3/6 
[+] and pair 4/5 [+], 7/8 [-]).
5.2  POE-171A series/POE-176-95 Installation
1. Connect the AC power adaptor to the “52-56V DC IN” of the POE-
171A series/POE-176-95; the “PWR” LED will be steadily on.
2. Connect a standard Ethernet cable from an Ethernet switch or PC 
workstation to the “Ethernet” port of the POE-171A series/POE-176-
95.
3. Connect the long cable to the “Ethernet+DC” port of the POE-171A 
series/POE-176-95 and the IEEE 802.3af/at/bt PD.
4. The POE-171A series/POE-176-95, adopting the IEEE 802.3af/at/
bt technology, can directly connect with any IEEE 802.3af/at/bt end-
nodes, such as PTZ (pan, tilt & zoom) network cameras, PTZ speed 
dome cameras, color touch screen, Voice over IP (VoIP) telephones 
and multi-channel wireless LAN access points as the screen in Figure 
3 is shown below.

Once the POE-171A series/POE-176-95 detects the existence of an IEEE 
802.3af/at/bt device, the PoE-in-Use LED indicator will be steadily on 
to show it is providing power.
Note
1. The 10Gbps speed is available for the POE-176-95 only.
2. Since the PoE port of the POE-171A series/POE-176-95 
supports 52-56V DC PoE power output, please check 
and assure the PD accepts DC power range of 52-56V 
DC. Otherwise, it will damage the PD.
