3. Use the screws to screw the wall-mount plate on the
industrial gigabit Ethernet switch.
4. Use the hook holes at the corners of the wall-mount plate
to hang the industrial gigabit Ethernet switch on the wall.
5. To remove the wall-mount plate, reverse the steps above.
Troubleshooting
This section contains issue-solving information. If the industrial
gigabit Ethernet switch is not functioning properly, ensure that
the industrial gigabit Ethernet switch was set up according to
instructions in this manual.
Issue
Solution
The per port LED does not
illuminate.
Check the cable connection and
try swapping out a cable.
Performance is poor
Check the speed duplex mode of
the partner device. The industrial
gigabit Ethernet switch is run in
auto-negotiation mode and if the
partner is set to half duplex, then
the performance will be poor.
Theper port LED illuminates,
but the traffic is irregular.
Ensure that the attached device
is not set to dedicated full duplex.
Some devices use a physical or
software switch to change duplex
modes. Auto-negotiation may not
recognize this type of full-duplex
setting.
The industrial gigabit
Ethernet switch doesn’t
connect to the network
Check the per port LED and/or try
another port on the industrial
gigabit Ethernet switch. Ensure
that the cable is installed properly
and is the correct type. Turn off
the power and then, after a while,
turn on the power again.

There are eight wires on a standard UTP/STP cable and each
wire is color-coded. Figure 3 on page 5shows the pin allocation
