5. Hardware Installation
The following section describes the hardware features of PoE-171
and POE-171S. Before connecting any network device to them,
please read this chapter carefully.
Please refer to following sections for detailed information about
POE-171
5.1 Before Installation
Before your installation, it is recommended to check your
network environment. If there is any IEEE 802.3at device that
needs higher power to be powered on and works normally,
the POE-171 provides you with a way out to supply power to
this Ethernet device conveniently and easily. The POE-171 is
equipped with a power adaptor which is 100-240V AC input and
injects DC 56V power into the pin of the twisted pair cable (pair
1/2 [-], 3/6 [+] and pair 4/5[+], 7/8[-]).
If there is difficulty in finding a power socket for AC-DC adapter
of your non-PoE IEEE 802.3at networked device, the POE-171
and POE-171S (Ultra PoE Splitter) provide you with a way out to
supply DC power to this Ethernet device conveniently and easily.
Note
The POE-171 and POE-171S can be installed in
a pair. However, the use of third-party device is
allowed if the device complies with IEEE 802.3at
Power over Ethernet.
5.2 The POE-171 Installation
1. Connect the AC power adaptor to “52-56V DC IN” of
POE-171; the “PWR” LED will be steadily on.
