Displaying detected connection errors
In the state on delivery, the device displays a detected connection error
via the signal contact and the LED display. The device allows you to
suppress this display, because you do not want to interpret a switched off
device as an interrupted connection, for example.
Configure Power over ETHERNET
If the device is equipped with PoE media modules, it will then allow you to
supply current to devices such as IP phones via the twisted-pair cable.
PoE media modules support Power over ETHERNET according to IEEE
802.3af.
On delivery, the Power over ETHERNET function is activated globally and
on all PoE-capable ports.
Nominal power for MS20/30, MACH 1000 and PowerMICE:
The device provides the nominal power for the sum of all PoE ports plus
a surplus. Because the PoE media module gets its PoE voltage
externally, the device does not know the possible nominal power.
The device therefore assumes a “nominal power” of 60 Watt per PoE
media module for now.
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:Port Configuration dialog.
In the "Propagate connection error" column, select the ports for
which you want to have link monitoring.
