Connecting architecture with IEEE 802.3af/at/bt device
Once POE-171A series 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
Since the PoE port of POE-171A series supports
52-56V DC PoE power output, please check and
assure the powered device (PD) accepts DC power
range of 52-56V DC. Otherwise, it will damage the
powered device (PD).
5.3 POE-171A series and POE-172S Installation
Note
Please turn off POE-172S before you switch to DC
power output mode.
1. Adjust proper DC power output and connect DC plug from
“DC OUT”
of POE-172S to remote device.
2. Connect the power adaptor to
“52-56V DC IN”
of POE-171A
series; the
“PWR”
LED will be steadily on.
3. Connect a standard Ethernet cable from
“EDC”
port of POE-171A series to
“PoE In”
port of POE-172S. The
