Hardware Introduction
Switch Front Panel
The front panel of the Industrial Gigabit PoE+ Switch consists of Ethernet interfaces
and LED indicators.
Front View
Figure 1: MC352-4P-2S-V2 Front View
PoE Power Usage LED
The front panel of the Industrial Gigabit PoE+ Switch has four LEDs that indicate PoE
Power Usagesof 30W, 60W, 90W and 120W. With these LED indications, you can
monitor the current PoE power in use status of Industrial Gigabit PoE+ Switch easily
and efficiently.

MC352-4P-2S-V2 User Manual 7
DIP Switch
The front panel of the Industrial Gigabit PoE+ Switch provides one DIP Switch for
configuring fiber redundant function.
The DIP Switch settings and descriptions:
Fiber Mode (DIP Switch)
Switch (Default Mode) This mode allows the Industrial Gigabit
PoE+ Switch to use 6 ports.
Redundant This mode allows one of the two SFP
ports to be redundant while the other 5
ports are in operation.
Redundancy Overview
The Industrial Gigabit PoE+ Switch provides rapid link fiber redundancy for critical
Ethernet applications;the redundant mode supports auto-recover function. If the link of
the destination port of a packet is down, it will forward the packet to the other port of the
backup pair. The following figure shows the redundant functions.
Figure 2: Redundancy Behavior Topology
Note: Using the Redundant mode, port 5 is defined as Primary Port and port 6 as
Backup Port.

Switch Upper Panel
The upper panel of the Industrial Gigabit PoE+ Switch consists of one terminal block
connector within two DC power inputs. Figure 3 shows the upper panel of the Industrial
Gigabit PoE+ Switch.
Figure 3: Industrial Gigabit PoE Switch Upper Panel
Wiring the Power Inputs
The six-contact terminal block connector on the top panel of Industrial Gigabit PoE+
Switch is used for two redundant power inputs. Please follow the steps below to insert
the power wire.
Caution: When performing any of the procedures like inserting the wires or tightening
the wire-clamp screws, make sure the power is OFF to prevent from getting an electric
shock.
To insert the power wire:
1. Insert positive and negative DC power wires into contacts 1 and 2 for POWER 1, or
contacts 5 and 6 for POWER 2.
V1+ V1- V2+ V2-
2. Tighten the wire-clamp screws for preventing the wires from loosening.

Note: The wire gauge for the terminal block should be in the range between 12 and 24
AWG.
Wiring the Faulty Alarm Contact
The faulty alarm contacts are in the middle of the terminal block connector as the
picture shows below. Inserting the wires, the Industrial Gigabit PoE+ Switch will detect
the fault status of the power failure and then forms an open circuit. The following
illustration shows an application example for wiring the faulty alarm contacts.
Note:
1. The wire gauge for the terminal block should be in the range of 12 ~ 24 AWG.
2. Alarm relay circuit accepts up to 24 V, max. 1 A currents.
Grounding the Device
The device must be correctly grounded to avoid serious damage.
Insert the wires into the fault alarm contacts

Installation
This section describes how to install the Industrial PoE+ Switch on the DIN rail and
wall.
Note: The following pictures show how to install the device. However, the device in the
picture is not MC352-4P-2S-V2.
Mounting the DIN rail
The DIN rail bracket is screwed on the Industrial PoE+ Switch when shipped. You need
an Industrial PoE+ Switch when replacing the wall-mount application with DIN rail
application.
To mount the Industrial PoE+ Switch:
1. Screw the DIN rail bracket on the Industrial PoE+ Switch.
2. Carefully insert the bottom of the switch into the track, as shown below.
3. Ensure the DIN rail bracket is tightly secured on the track.

MC352-4P-2S-V2 User Manual 13
4. Please refer to the following procedure to remove the Industrial PoE+ Switch from
the track.
Mounting the Wall-mount Plate
To install the Industrial PoE+ Switch on the wall:
1. Loosen the screws to remove the DIN rail bracket from the Industrial PoE+ Switch.
2. Place the wall-mount plate on the rear panel of the Industrial PoE+ Switch.
3. Use the screws to attach the wall-mount plate on the Industrial PoE+ Switch.
4. Use the hook holes at the corners of the wall-mount plate to hang the Industrial
PoE+ Switch on the wall.
5. To remove the wall-mount plate, reverse the steps above.
