Configuring Power Over Ethernet - Hirschmann MACH 4000 User Manual

Configuring the ports
Displaying connection error messages
In the state on delivery, the Switch displays connection errors via the sig-
nal contact and the LED display. The Switch allows you to suppress this
display, because you do not want to interpret a switched off device as an
interrupted connection, for example.
Select the
Basics:Port Configuration dialog.
In the "Signal contact mask" column, select the ports for which you
want to have link monitoring.

Configuring Power over ETHERNET

If the Switch is equipped with PoE media modules, you will then have the
option of supplying current to devices such as IP phones via the twisted-
pair cable. PoE media modules support Power over ETHERNET accord-
ing to IEEE 802.3af.
On delivery, the Power over ETHERNET function is global and activated
on all ports.
System power for MS20/30 and Power MICE:
The Switch provides the nominal system power for the sum of all PoE
ports plus a surplus. Because the PoE media module gets its operating
voltage externally, the Switch does not know the possible system power.
The Switch therefore assumes for now a "nominal system power" of 60
Watt per PoE media module.
System power for MACH 4000:
The Switch provides the nominal system power for the sum of all PoE
ports plus a surplus. Should the connected devices require more power
than is provided by the system, the Switch then disables the ports. Initial-
ly, the Switch disables the ports with the lowest PoE priority. If multiple
ports have the same priority, the switch first disables the ports with the
higher port number.
Select the
Basics:Power over Ethernet dialog.
