2. Installation
This section describes the functionalities of the Industrial Gigabit PoE+ Switch’s components and guides
how to install it on the desktop. Basic knowledge of networking is assumed. Please read this chapter
completely before continuing.
2.1 Product Description
High Power PoE for Security and Public Service Applications
To fulfill the demand of High Power PoE for network applications with Gigabit speed transmission under
wide temperature, the MC352-4P-2S provide 4 10/100/1000Mbps ports featuring both IEEE 802.3af and
IEEE 802.3at Power over Ethernet Plus (PoE+) that combine up to 30-watt power output and data per
port over one Cat.5E / 6 Ethernet cable.
With a total of up to 120 watts of PoE output capability, the MC352-4P-2S is designed specifically to
satisfy the growing demand of higher power consuming network PDs (powered devices) such as PTZ
(Pan, Tilt & Zoom) speed dome network cameras, multi-channel (802.11a / b / g / n) wireless LAN access
points and other PoE network devices by providing double PoE power, rather than the current
conventional 802.3af PoE.
Environmentally Hardened Design
The MC352-4P-2S is equipped with rugged IP30 metal case for easy deployment in heavy Industrial
demanding environments. With IP30 metal case protection, the MC352-4P-2S provide a high level of
immunity against electromagnetic interference and heavy electrical surges which are usually found on
plant floors or in curb side traffic control cabinets. Being able to operate in the temperature range from
-40 to 75 Degree C, the MC352-4P-2S can be placed in almost any difficult environment. The
MC352-4P-2S allows either DIN rail or wall mounting for efficient use of cabinet space.
Adjustable 6-Port Switch Mode or 4 + 2 Fiber Redundant Mode
Via the built-in DIP switch, the MC352-4P-2S can be configured as 6-Port Ethernet switch or 4+2 fiber
redundant mode. With the 6-port switch mode, the MC352-4P-2S can operate in Store-and-Forward
mechanism with high performance; on the other hand, when in the 4+2 fiber redundant mode, it provides
rapid fiber redundancy of link for highly critical Ethernet applications. The redundant-mode also supports
auto-recovering function, if the destination port of a packet is link down, it will forward the packet to the
other port of the backup pair.

The fault 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, or
port link failure (available for managed model) and then forms an open circuit. The following illustration
shows an application example for wiring the fault alarm contacts.

2.1.6 Cabling
10/100/1000Base-T
All 10/100/1000Base-T ports come with Auto-Negotiation capability. They automatically support
1000Base-T, 100Base-TX and 10Base-T networks. Users only need to plug a working network device
into one of the 10/100/1000Base-T ports, and then turn on the Industrial Gigabit PoE+ Switch. The port
will automatically runs in 10Mbps, 20Mbps, 100Mbps or 200Mbps and 1000Mbps or 2000Mbps after the
negotiation with the connected device.
100Base-FX/1000Base-SX/LX
The MC352-4P-2S Industrial Gigabit PoE+ Switch has two SFP interfaces that support 100/1000 dual
speed mode (Optional Multi-mode/Single-mode 100Base-FX/1000Base-SX/LX SFP module) through
DIP switch setting.
Cabling
Each 10/100/1000Base-T port uses RJ-45 sockets -- similar to phone jacks -- for connection of
unshielded twisted-pair cable (UTP). The IEEE 802.3/802.3u/802.3ab Fast/Gigabit Ethernet standard
requires Category 5 UTP for 100Mbps 100Base-TX. 10Base-T networks can use Cat.3, 4, 5 or
1000Base-T uses 5/5e/6 UTP (see table below). Maximum distance is 100 meters (328 feet). The
100Base-FX/1000Base-SX/LX SFP slot is used as LC connector with optional SFP module. Please see
table below and know more about the cable’s specification.
Port Type Cable Type Connector
10Base-T Cat 3, 4, 5, 2-pair RJ-45
100Base-TX Cat.5 UTP, 2-pair RJ-45
1000Base-T Cat.5/5e/6 UTP, 4-pair RJ-45
100Base-FX 50/125µm or 62.5/125µm multi-mode

1000Base-SX/LX 50/125µm or 62.5/125µm multi-mode
9/125µm single-mode LC (Multi/Single mode)
Any Ethernet devices like hubs/PCs can be connected to the Industrial Gigabit PoE+ Switch by using
straight-through wires. The four 10/100/1000Mbps ports are auto-MDI/MDI-X and can be used on
straight-through or crossover cable.
2.1.6.1 Installing the SFP transceiver
The sections describe how to insert an SFP transceiver into the MC352-4P-2S SFP slot.
The SFP transceivers are hot-pluggable and hot-swappable. You can plug-in and out the transceiver
to/from any SFP port without having to power down the Industrial Gigabit PoE+ Switch as the Figure 2-3
appears.

3. Check the LNK/ACT LED of the SFP slot of the switch / converter. Ensure that the SFP transceiver
is operating correctly.
2.1.6.2 Remove the Transceiver Module
1. Make sure there is no network activity by consulting or checking with the network administrator. Or
through the management interface of the switch/converter (if available) to disable the port in
advance.
2. Remove the Fiber Optic Cable gently.
3. Turn the latch of the SFP module to a horizontal position.
4. Pull out the module gently through the latch.

Figure 2-4: Pulling out from the transceiver
Never pull out the module without pulling the latch or the push bolts on the
module. Directly pulling out the module with violence could damage the module
and the SFP module slot of the Industrial Gigabit Ethernet Switch.
2.1.7 Redundancy Overview
The MC352-4P-2S Industrial Gigabit PoE+ Switch provides rapid fiber redundancy of link for highly
critical Ethernet applications. The redundant-mode supports auto-recover function. If the destination port
of a packet is link down, it forwards the packet to the other port of the backup pair. The following figure
shows the redundant function.

Link status auto detect and redundant on Dual ports with same connector type.
Only Primary-Port is active at a time, the Backup-Port is blocked.
When Primary-Port link failure occurs, the traffic swaps to Backup-Port automatically.
Once the Primary-Port status is back to link up, the traffic will swap from Backup-Port to
Primary-Port.
2.2 Mounting Installation
This section describes how to install the Industrial Gigabit PoE+ Switch and make connections to it.
Please read the following topics and perform the procedures in the order being presented.
In the installation steps below, this Manual uses IGS-801 (IFS 8 Port Industrial Gigabit
Switch) as the example. However, the steps for IFS Industrial Gigabit PoE+ Switch are
similar.
2.2.1 DIN-Rail mounting
The DIN-Rail is screwed on the Industrial Gigabit Ethernet Switch when out of factory. When needed to
replace the wall mount application with the DIN-Rail application on Industrial Gigabit Ethernet Switch,
please refer to the following figures to screw the DIN-Rail on the Industrial Gigabit Ethernet Switch. To
hang the Industrial Gigabit Ethernet Switch, follow the steps below:
