8~14-Port Managed Ethernet Switch
Quick Installation Guide
Overview
The Managed Ethernet Switch solutions are designed for supporting standard industrial
applications. Managed switches are easier to prioritize, partition, and organize user’s network,
providing a more reliable and better quality services.
Package Checklist
Please verify the box contains the following items:
Management Ethernet switch
M3 Screws (for the wall mount plates & DIN CLIP)
RJ45 Ethernet port Dust Cover
SFP Ethernet port Dust cover

Safety Instructions
When a fiber connection is removed during installation, testing, servicing or an active fiber is
broken, ocular exposure to optical energy may be potentially hazardous, depending on the
laser output power.
The primary hazards of exposing laser radiation from an optical-fiber communication systems
are:
●
Damage to eyes from accidental exposure to a beam emitted by a laser source.
●
Damage to eyes from viewing the connector that attaches to a broken fiber or an
energized fiber.

Mounting steps:
1. Screw the din-clip with screws in the accessory kit.
2. Hook the unit onto the din-rail.
3. Push the bottom of the unit towards the din-rail until it locks in place.

Ethernet Interface (RJ45 Ethernet)
The switch provides two types of Ethernet interfaces: electrical (RJ45) and optical (SFP)
interfaces.
Connecting the Ethernet interface via RJ45:
●
To connect the switch to a PC, use straight-through or cross-over Ethernet cables,
●
To connect the switch to an Ethernet device, use UTP (Unshielded Twisted Pair) or
STP (Shielded Twisted Pair) Ethernet cables.
The pin assignment of RJ-45 connector is shown in the following figure and table.
MLB-E42xx
MLB-E42xx-P
Ethernet Interface (Fiber, SFP)
For both 100/1000 Mbps fiber speed connections, the SFP slots are available. The SFP slot
accepts the fiber transceivers that typically have an LC connector.
The fiber transceivers have options of multimode, single mode, long-haul or specialapplication transceivers.
DANGER: Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical
fiber and putting the dust cover in position, as laser outputs will emit
infrared laser light at this point.

Connecting Power Terminal Block
The switch can be powered from two power supplies (input range 12V – 58V). Insert
the positive and negative wires into V+ and V- contacts on the terminal block
respectively and tighten the wire-clamp screws to prevent the wires from being
loosened.
Note: 1. The DC power should be connected to a well-fused power supply.

Alarm Relay and Ground
The alarm relay output contacts are in the middle of the DC terminal block connector as
shown in the figure below.
The alarm relay out is “Normal Open”, and it will be closed when detected any predefined
failure such as power failures or Ethernet link failures.

Console Connection
The Console port is for local management by using a terminal emulator or a computer with
terminal emulation software.

●
8 data bits, 1 stop bit
●
None Priority

None flow control

To connect the host PC to the console port, a RJ45 (male) connector-to-RS232 DB9 (female)
connector cable is required. The RJ45 connector of the cable is connected to the CID port of
IVS-500; the DB9 connector of the cable is connected to the PC COM port. The pin
assignment of the console cable is shown below:
