1Overview
1.1 Introduction
This manual covers the ESML6-FL2 series. The KBC ESML6-FL2 products are high
performance, managed, eight-port industrial Ethernet switches designed for use in a
wide range of operating temperatures in non-environmentally conditioned, industrial
applications. Redundancy is offered through the DT-Ring technology that recovers
cable or port failures automatically in less than 100ms. The unit has redundant
power supply terminals and an alarm output for power supply and uplink port
failure.
1.1.1 ESML6-FL2
The ESML6-FL2 is a managed switch which provides 6, 10/100 twisted pair copper
ports two of which can be configured as uplink redundant ports and an additional
two uplink, full-duplex, multimode or singlemode 100Mbps fiber ports. The switch is
capable of dual redundant ring operation. Each copper port supports a self-adaptive
function allowing it to be configured to 10Base-T or 100Base-TX, full or half-duplex
operation mode, supporting automatic MDI/MDI-X connection. The settings of the
DIP switch (see Page 9) sets the mode of uplink ports 1,2,4 & 8 (see Figure. 2.1) as
either straight-through, redundant, master or slave. The switch is available as either
a DIN rail or wall-mount configuration.

2.5 Ethernet RJ45 Connections
2.5.1 RJ45 Ethernet Ports
The ESML6-FL2 offers 4, 10/100 Base T/TX RJ45 ports numbered 3, 5, 6 & 7 (see
figure 2.1). Each port is adaptive and supports auto MDI/MDI-X connection. They
can be connected by straight through or cross-over cables to terminal devices,
servers, hubs or other switches. Each switch supports IEEE802.3x so the optimum
transmission mode (either half-duplex or full-duplex) and data rate (either 10Mbps
or 100Mbps) will be selected automatically. The connected devices should support
this feature too however, if the connected devices are not adaptive, the port will
send at the correct rate but with default mode of half-duplex.
2.5.2 Uplink Redundant Ethernet RJ45 ports
The ESML6-FL2 has 2 uplink redundant RJ45 ports: ports 1 & 2 (see Figure 2.1).
These two ports can be set in either straight-through mode or redundant mode. In
the straight-through configuration they are set as normal Ethernet ports in
redundant mode they provide redundancy for a twisted pair network and have a
recovery time of less than 100ms.
2.6 Fiber Optic Connections
The ESML6-FL2 offers two pairs of uplink redundant 100Base-FX, full-duplex fiber
ports, ports 4 & 8 (see Figure 2.1) which can be either singlemode or multimode.
Each optical connector is a duplex SC. The interface should be used in a pair (Tx and
Rx), where the Tx interface is the optical transmitting terminal which connects to the
optical receiving terminal (Rx) of the remote device. The optical Rx is the receiving
terminal which connects to the transmitting terminal (Tx) of the same optical
interface of the remote device. The two pairs of uplink redundant fiber ports can be
used to form a fiber optic redundant ring network. If a system failure occurs, the
redundant recovery time of the ring network is less than 100ms.

Figure 2.1 Switch Ports
2.7 Grounding / Earthing
The ESML6-FL2 has an earth point located on the top panel of the switch. To achieve
the best earth connection, a circular cold-press terminal should be crimped to one
end of the earth wire and attached to the unit with the screw, making sure that the
star washer stays in contact with the body of the switch. The cross-section of
grounding wire should not be less than 2.5mm2.

2.8 DIP Switch Setting
The DIP switch settings are used to set the fiber and copper uplink ports to either
redundant mode (in a ring configuration) or straight-through (not in a ring
configuration) and if they are in redundant mode then whether they are a master or
slave.
Note: In a redundant ring network, only one switch can be set as the master and
others are set as slaves.

2.10 Power Input Terminals
The ESML6-FL2 has two green screw terminal blocks (Power Input 1 & Power Input
2) mounted on the top panel of the switch, see Figure 2.3. The power inputs can be
used independently or they can be connected to two separate external 24V DC
power supplies to provide redundancy. The red sleeved wire should be connected to
the +ve power input and the blue sleeved wire should be connected to the –ve
power input of the green male screw block terminal.
Figure 2.3 Power Input Terminals
2.11 Alarm Relay Output
The alarm terminal, which is also a green screw block terminal, (see Figure 2.3) has
a relay output. Under normal conditions the relay is open if there is a failure of
either of the power supplies the terminal relay becomes closed. This terminal can be
connected to other switching devices, lights or alarms to indicate that a power
source has been lost. The maximum voltage this terminal can be connected to is
350Vdc and maximum current is 120mA (see the diagram below for an example of
this kind of set up).

2.12 RS232 Console Interface
The console interface on the ESML6-FL2 is a shielded RJ45 connector based on 3-line
RS232. The switch can be connected to a 9 pin serial port of a pc using a cable with a
DM9F connector. Hyper Terminal software in Windows can be used to gain access to the
switch software in order to configure, monitor and manage the switch. For further
information on accessing the management software please see separate software
management manual for this switch.
3Troubleshooting
3.1 Self-testing
When the device is powered on, the Power LED will be illuminated showing that there is
power to the unit. The RUN LED will be either on, flashing or off depending on the DIP
switch setting (see Figure 2.2).
3.2 Twisted Pair Port Testing
As shown in Figure 3.1, with the switch powered on, connect two RJ45 ports from the
switch to two test computers and send the “ping” command between each computer. If
both the computers receive the complete command without packet loss and the green
LED flashes, this means that the two RJ45 ports are working correctly. Test the other
RJ45 ports as required, using the same method. During normal operation the green
LINK/ACT LED will flash to show data transfer and the yellow 10M/100M will either be off
to show 10Mbps (10BASE-T) operation or on to show 100Mbps (100BASE-TX) operation.

3.3 Fiber Port Testing
As shown in Figure 3.2, connect two ESML6-FL2 units via their fiber ports. Then
attach a computer to any RJ45 port on each device using a straight though cable and
send the “ping”command between the connected computers. If both computers get
the command without packet loss and the corresponding LINK/ACT indicators of the
fiber ports flash, this then shows the fiber ports under test are functioning correctly.

The ESML6-FL2 offers 6, RJ45 10/100Base-TX ports each of which can be connected
to terminal devices directly or to another industrial Ethernet switch or hub. The
ESML6-FL2 also has 2 pairs of uplink 100Base-FX fiber ports which can be used to
form a redundant optical ring which has a recovery time of less than 100ms. A
typical redundant ring set up is shown in Figure 5.1 below.
