1.5 Power over ETHERNET
For the devices
OS24-080900T5T5TFFBHH
OS24-080900T5T5TNEBHH
The device supports Power over ETHERNET according to IEEE 802.3at
(PoE+) and allows you to supply current to devices such as IP phones via the
twisted-pair cable.
On delivery, the Power over ETHERNET function is activated globally and on
all PoE-capable ports.
The device provides a nominal power of 61.1 W for the sum of all PoE ports.
Should the connected devices require more PoE power than is provided, the
device then switches PoE off at the ports. The device first switches PoE off
at the ports with the higher port number.
With “Function on/off” you turn the PoE on or off.
With “Send Trap” you can get the device to send a trap in the following
cases:
– If a value exceeds/falls below the performance threshold.
– If the PoE supply voltage is switched on/off at at least one port.
Enter the power threshold in “Threshold”. When this value is exceeded/
not achieved, the device will send a trap, provided that “Send trap” is
enabled. For the power threshold you enter the power yielded as a
percentage of the nominal power.
“Nominal Power” displays the power that the device nominally provides
for all PoE ports together.
“Reserved Power” displays the maximum power that the device provides
to all the connected PoE devices together on the basis of their
classification.
“Delivered Power” shows how large the current power requirement is at
all PoE ports.
The difference between the "nominal" and "reserved" power indicates how
much power is still available to the free PoE+ ports.
In the “POE on” column, you can enable/disable PoE at this port.
The “Status” column indicates the PoE status of the port.
