Wiring the power inputs
The six-contact terminal bloc k connect or on the top panel of
industrial gigabit Ethernet switch is used for two DC redundant
power inputs. Follow the steps below to insert the power wire.
1. Insert positive and negative DC power wires into contacts
1 and 2 for Power 1 or 5, and 6 for Power 2.
Insert the wires into the fault alarm contacts.
Note:
1. The wire gauge for the terminal block should be in the
range between 12 to 24 AWG.
2. Alarm relay circuit accepts up to 30 V, max. 3 A currents.
V1+ V1 - V2 + V2 -
2. Tighten the wire-clamp screws for preventing the wires
from loosening.

Wiring the fault alarm contact
The fault alarm contacts are in the middle of the terminal block
connector. Upon inserting the w ir es, the industrial gigabit
Ethernet switch detects the fault status of the power failure and
then forms an open circuit. The following illustration shows an
application example for wiring the fault alarm contacts.

Mounting
Note: Ensure that the industrial managed switch is mounted
vertically with the power connectors on the top and a minimum
of three inches above and below the switch to allow for proper
air flow. This device uses a convection flow of hot air which
rises and brings cold air in from the bottom and out of the top
of the device. Do not mount the switch horizontally as this does
not allow air to flow up into the device and will result in damage
to the switch. Do not tie DC1 to DC2. DC2 is for secondary
power redundancy. Do not plug DC power into the device while
the AC power cord is plugged in. This is not a hot-swappable
switch. Hot-swapping this device will result in damage.
3. Ensure that the DIN-rail is secured to the track.
DIN-rail mounting installation
To replace the wall-mount application with DIN-rail application
on industrial gigabit Ethernet switch, refer to the following
figures to screw the DIN-rail on the industrial gigabit Etherne t
switch.
To hang the industrial gigabit Ethernet switch, follow the steps
below:
1. Screw the DIN-rail on the industrial gigabit Ethernet
switch.
2. Place the bottom of DIN-rail lightly into the track.
To remove the industrial gigabit Ethernet switch from the track,
carefully pull out the bottom of the DIN-rail to remove it from
the track.
Wall-mount plate mounting
To install the industrial gigabit Ethernet switch on the wall,
follow the steps below.
1. Remove the DIN-rail from the industrial gigabit Ethernet
switch. Loosen the screws to remove the DIN-rail.
2. Place the wall-mount plate on the rear panel of the
industrial gigabit Ethernet switch.

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.
Performance is poor
Theper port LED illuminates,
but the traffic is irregular.
The industrial gigabit
Ethernet switch doesn’t
connect to the network
Check the cable connection and
try swapping out a cable.
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.
Ensure that the attached device
is not set t o 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.
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.
