Note
If a device is connected to a port with PoE capability, a check is made to determine whether
the power of the port is adequate for the connected device.
If the power of the port is inadequate, although PoE is enabled in "Setting", the port
nevertheless has the status "disabled". This means that the port was disabled by the PoE
power management.

Port Diagnostics

5.4.22.1

Cable Tester

With this page, each individual Ethernet port can run independent fault diagnostics on the
cable. This test is performed without needing to remove the cable, connect a cable tester and
install a loopback module at the other end. Short-circuits and cable breaks can be localized to
within a few meters.
Note
Please note that this test is permitted only when no data connection is established on the port
to be tested.
If, however, there is a data connection to the port to be tested, this is briefly interrupted.
Automatic re-establishment of the connection can fail and then needs to be done manually.
240
The PoE power supply is deactivated for this port.
The PoE power supply is activated for this port and a device is connected.
The PoE power supply is activated for this port but there is no device connected.
