1.2.2 Pressing the Mode Button to Detect Power-Feeding on a Port
By default, S3026C-PWR feeds power to its connected PDs through signal lines.
However, some PDs are actually powered via spare lines. Therefore, you can press the
"mode" button on the front panel of S3026C-PWR to perform reverse detection on the
connected PDs so as to find the "some" and feed power to them. The detection itself
does not impact the ongoing power-feeding ports, for it only detects those ports that are
not in service. Once it finds any PDs connected on certain ports are powered via spare
lines, the system will supply power to them. The left LED of a port indicates the port
power-feeding status: ON means the port is in service; OFF means the port is not in
service; flashing means the port operates abnormally. The detection stops in 45
seconds. And then the ports not in service restore to signal lines mode.
1.2.3 Selecting the Power-Feeding Mode on a Port
S3026C-PWR is capable of concurrent data transfer and current transfer through the
signal lines 1, 3, 2 and 6 in category-3/category-5 twisted pairs. Alternatively, it can also
use the signal lines 1, 3, 2 and 6 in category-3/category-5 twisted pairs to transfer data
and use the spare lines 4, 5, 7 and 8 to transfer current. You can opt for either power
supply mode by inputting command lines or pressing the mode button.
You can select the power-feeding mode of a current port by executing the following
commands.
Perform the following configurations in Ethernet port view.
