Configuring the ports
Nominal power for MACH 4000:
The device provides the nominal power for the sum of all PoE ports plus
a surplus. Should the connected devices require more PoE power than is
provided, the device then switches PoE off at the ports. Initially, the device
switches PoE off at the ports with the lowest PoE priority. If multiple ports
have the same priority, the device first switches PoE off at the ports with
the higher port number.
Select the
Basics:Power over Ethernet dialog.
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 follow-
ing 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 exceed-
ed/not achieved, the device will send a trap, provided that "Send
trap" is enabled. For the power threshold you enter the power yield-
ed as a percentage of the nominal power.
"Nominal Power" displays the power that the device nominally pro-
vides for all PoE ports together.
"Reserved Power" displays the maximum power that the device pro-
vides 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.
