powering will not be activated.
Note: During the PoE operating, the surface will accumulate heat and caused surface
temperature becomes higher than ambient temperature. Do remember don’t touch
device surface during PoE operating.
Note: To enable the IEEE 802.3at High Power PoE function, the power input voltage is
required to be larger than DC 54V to obtain better performance. Applies voltage lower than
DC 54V to PoE Switch but connecting to a PD in performing 30W high power output may
cause the PoE function of the switch to be disabled automatically, due to the OCP (output
current protect) mechanism is activated (
0.686A current is design as OCP design
). To avoid
this issue, it is required a professional engineer to adjust the power supply output to 54V
DC, by setting variable resistor equipped in the switching power supply.
For the JetNet 6910G-M12 series, the internal DC/DC output voltage is required DC
54V at minimum; so the a lower value in “power budget” may not impact when a high
DC 110V input is presented.
PD Status Detection (Link Partner Line Detect)
JetNet 6910G-M12 delivers a convenient function –
PD Status Detection. This provides automatic
detection of a remote device powered by JetNet
6910G-M12. If the remote system crashes or is
unstable, JetNet PoE Switch will perform a remote
system reboot by turning off and on again to trigger
the remote device. The following figure shows the
Web configure interface for Power over Ethernet PD
Status Detection.
Administrator can enable/disable PD Status
Detection function and type in the IP address that you want to detect. The Cycle Time is
the gap per detection. After configuring, please click the Apply button to enable and
perform the functions.
