2. Connect a standard Ethernet cable from an Ethernet switch or
PC workstation to “Ethernet” port of POE-171.
3. Connect the long cable to “Ethernet+DC” port.
4. Connect with IEEE 802.3at/802.3af devices. Due to the
capability of IEEE 802.3at/802.3af Power over Ethernet, the
POE-171 can directly connect with any IEEE 802.3at/802.3af
end-nodes, such as PTZ (Pan, Tilt & Zoom) network cameras,
PTZ speed dome, color touch-screen, Voice over IP (VoIP)
telephones and multi-channel wireless LAN access points
which support IEEE 802.3at/802.3af In-line Power over
Ethernet port. The screen in Figure 3 appears.

Once POE-171 detects the existence of an IEEE 802.3at/802.3af
device, the PoE In-use LED indicator will be steadily on to show
it is providing power.
