7. “Link/Act” LED of port will be ON if network connection works.
8. “PoE out” LED of port will be ON if PoE power is delivering.
9. If “PoE out” LED blink, remove the connection because it is overload.
Here is the application note for this application.
1. The system PoE budget is 60W.
2. It is 30W maximum per port for 802.3at connection, and 60W total
maximum for Port 1~4.
3. PoE power allocation on port is according to the class of PD. And it
is Class 1: 4W, Class 2:7W, Class 3:15W, Class 4: 30W, Class 0:
13W.
4. When no system budget is available, “PoE Max” LED will be ON.
5. When total PoE delivering power on Port 1~4 > 60W, “PoE Max” LED
will Blink.
6. Port priority is only for PoE+ Extender Switch starting to power ON.
And it is Port 4 > Port 3 > Port 2 > Port 1. After power ON, there is
no port priority.
6.4 Powered with Uplink PoE Connection
Follow the steps for installation.
1. Connect uplink PoE connection to Uplink port.
2. “Power” LED will be ON if PoE+ Extender Switch receives power
from Uplink connection.
3. “PoE in” LED will be ON if it is a 802.3at connection. (It will be OFF
for a 802.3af connection.)
4. “Link/Act” of Uplink port will be ON if network connection works.
5. Connect PoE PD devices to Port 1~4.
6. “Link/Act” LED of port will be ON if network connection works.
7. “PoE out” LED of port will be ON if PoE power is delivering.
8. If “PoE out” LED blink, remove the connection because it is overload.
Here is the application note for this application.
> 802.3at PoE connection on Uplink port
1. The system PoE budget is 20~22W. (It depends on the PoE voltage
from Uplink port. The PoE voltage is 50~57V for 802.3at spec.
More power could be delivered with higher PoE voltage.)
2. Per port delivering power or Port 1~4 total delivering power cannot
over system PoE budget.
3. PoE power allocation on port is according to the class of PD. And it
is Class 1: 4W, Class 2:7W, Class 3:15W, Class 4: system budget,
