Displaying connection error messages
In the state on delivery the Switch displays a connection error via the
signal contact and the LED display. The Switch allows you to disable the
displaying of connection error messages, for instance to prevent a
device that has been turned off from being interpreted as an interrupted
line.
U
Configuring Power over ETHERNET
If the Switch is equipped with PoE media modules, it will then offer you
the option of supplying current to devices such as IP phones via the
twisted-pair cable. PoE media modules support Power over ETHERNET
according to IEEE 802.3af.
The Power over Ethernet function is activated global and on all ports by
default.
Systempower for MS20/MS30 and Power MICE
The Switch provides the rated system performance 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 a “nominal system power” of 60 Watt per
PoE media module for now.
System power for MACH 4000
The Switch provides the rated system performance 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 will then disable the
ports. Initially, the Switch disables the ports with the lowest PoE priority. If
several ports have the same priority, the switch will first disable the ports
with the higher port number.
