The response is displayed in the status line. If there is an active
connection, the message appears: "Ethernet 10/100/1000 Mbit
connection“
and only the identified speed is displayed.
If the port is not active, "No connection" is displayed. Then you can switch
to one of the 4 tone transmission modes. The trace tone is transmitted on
all of the wire pairs. The assigned port in the patch panel can be clearly
identified with the PROBE.
PoE/PoE+ test per IEEE 802.3af/at
Start the test by pressing the SEL button. The
KE7200 / KE7100
activates the PoE port and shows in the display whether the PoE is
available or not. If the PoE can be activated, it is. Then the maximum load
is applied to drain the cable charge. The maximum available power is
then measured. This is done according to IEEE 802.3af and to IEEE
802.3at. The standard regulates the voltage that can be on the line when
a specific current is flowing. If the voltage is below the standard value, the
KE7200 / KE7100
reduces the load until the voltage lies within the
normal range. This power is then calculated and displayed.
Start the test
new for each measurement.
This information is important in every network with PoE powered devices
since faults repeatedly arise because the power supply in the switch has
reached the limit. If a small, additional load is created, for example from
different operating conditions such as turning on an infrared light, the
network fails and the switch only provides the emergency power. This
situation cannot be detected without the proper test equipment.
IP test
–
KE7200 only
In the IP test, the
KE7200
can search the network for IP addresses and
users. This can be done in DHCP mode or with a fixed IP. If the network
is also monitoring MAC addresses, the MAC address of the
KE7200
can
be changed.
First, DHCP mode is started by selecting "IP test/DHCP request". A
connection to the network is established. Once this is available, it is
shown in the status line. The IP address allocated to the
KE7200
via DHCP is displayed. The search for allocated IP addresses starts
immediately in the assigned address space. The number found is also
displayed. The
KE7200
then queries all of the addresses for information
which it lists. If names are available, they are displayed; if not, only the IP
address is displayed.
This procedure can take a while, especially if there are many users in the
network. You can monitor the changing of the found IP addresses.
