DIN-Rail Mounting

The aluminum DIN-rail attachment plate should already be fixed to the back
panel of the EDS when you take it out of the box. If you need to reattach the
DIN-rail attachment plate, make sure the stiff metal spring is situated towards
the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN-rail into the
slot just below the stiff metal spring.

STEP 2:

The DIN-rail attachment unit will
snap into place as shown below.

To remove the DIN-rail from the EDS, simply reverse Steps 1 and 2.

Wall Mounting (optional)

For some applications, you will find it convenient to mount the EDS on the
wall, as illustrated below.

STEP 1:

Remove the aluminum
DIN-rail attachment plate
from the EDS’s rear panel,
and then attach the wall
mount plates, as shown in
the figure.

⇒

STEP 2:

Mounting the EDS on the wall requires 4 screws. Use the switch,
with wall mount plates attached, as a guide to mark the correct
locations of the 4 screws. The heads of the screws should be less
than 6.0 mm in diameter, and the shafts should be less than 3.5
mm in diameter, as shown in the figure at the right.

6.0 mm

3.5 mm

NOTE

Before tightening screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.

Do not screw the screws in all the way—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.

STEP 3:

Once the screws are fixed in the
wall, insert the four screw
heads through the large parts of
the keyhole-shaped apertures,
and then slide the EDS
downwards, as indicated.
Tighten the four screws for
added stability.

Wiring Requirements

WARNING

Safety First!

Turn the power off before disconnecting modules or wires. The
proper power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT use a voltage greater than what is
specified on the product label.

These devices must be supplied by an AELV source as defined in

the Low Voltage Directive 2006/95/EC and 2004/108/EC.

WARNING

Safety First!

Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could

overheat, causing serious damage to your equipment.

You should also pay attention to the following items:

y Use separate paths to route wiring for power and devices. If power wiring

and device wiring paths must cross, make sure the wires are perpendicular
at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring in
the same wire conduit. To avoid interference, wires with different signal
characteristics should be routed separately.

y You can use the type of signal transmitted through a wire to determine

which wires should be kept separate. The rule of thumb is that wiring with
similar electrical characteristics can be bundled together.

y Keep input wiring and output wiring separated.
y It is strongly advised that you label wiring for all devices in the system

when necessary.

Grounding Moxa EtherDevice Switch

Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded
mounting surface, such as a metal panel.

Wiring the Alarm Contact

The Alarm Contact consists of the two middle contacts of the terminal block on
the EDS’s top panel. You may refer to the next section for detailed instructions
on how to connect the wires to the terminal block connector, and how to attach
the terminal block connector to the terminal block receptor.

In this section, we explain the meaning of the two contacts used to connect the
Alarm Contact.

FAULT

FAULT

Top View

Front View

FAULT: The two middle contacts of the

6-contact terminal block connector are used to
detect both power faults and port faults. The
two wires attached to the Fault contacts form
an open circuit when:

1. EDS has lost power from one of the AC/

DC power inputs.
OR

2. The PORT ALARM DIP switch for one of

the ports is set to ON, but the port is not

connected properly.

If neither of these two conditions is satisfied,
the Fault circuit will be closed.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 6-contact terminal
block connector on the EDS’s top panel are used for the EDS’s two AC/ DC
inputs. Top and front views of one of the terminal block connectors are shown
here.

Top View

Front View

STEP 1: Insert the negative/positive AC/

DC wires into the V-/V+ terminals.

STEP 2: To keep the AC/ DC wires from

pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp
screws on the front of the terminal block
connector.

STEP 3: Insert the plastic terminal block

connector prongs into the terminal block
receptor, which is located on EDS’s top
panel.

ATTENTION

Before connecting the EDS to the AC/DC power inputs, make
sure the AC/DC power source voltage is stable.

Communication Connections

EDS-G308 models have 8 10/100/1000BaseT(X) Ethernet ports, or 6
10/100/1000BaseT(X) and 2 combination ports—10/100/1000T(X) and
100/1000BaseSFP.

10/100/1000BaseT(X) Ethernet Port
Connection

The 10/100/1000BaseT(X) ports located on Moxa EtherDevice Switch’s front
panel are used to connect to Ethernet-enabled devices. Most users will choose
to configure these ports for Auto MDI/MDI-X mode, in which case the port’s
pinouts are adjusted automatically depending on the type of Ethernet cable
used (straight-through or cross-over), and the type of device (NIC-type or
HUB/Switch-type) connected to the port.

In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.

100Base-FX or 1000Base-X Fiber Port

The Fiber ports on the EDS-G308 series are SFP type slots, which support both
100Base-FX and 1000Base-X speed fiber transceiver to work properly. Moxa
provides complete transceiver models for various distance requirements.

Multi-mode:

1000BaseSX 0 to 550 m, 850 nm (50/125μm, 400MHz*km)

0 to 275 m, 850 nm (62.5/125μm, 200MHz*km)

1000BaseLX 0 to 1100 m, 1310 nm (50/125μm, 800MHz*km)

0 to 550 m, 1310 nm (62.5/125μm, 500MHz*km)

Single-mode:

1000BaseLX 0 to 10 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))
1000BaseLHX 0 to 40 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))
1000BaseZX 0 to 80 km, 1550 nm (9/125μm, 19 PS/(nm*km))

Multi-mode:

100BaseFx 0 to 5 km, 1300 nm (50/125μm, 800MHz*km)

0 to 4 m, 1300 nm (62.5/125μm, 500MHz*km)

Single-mode:

100BaseFx 0 to 40 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))

The concept behind the LC port and cable is quite straightforward. Suppose
you are connecting devices I and II. Unlike electrical signals, optical signals do
not require a circuit in order to transmit data. Consequently, one of the optical
lines is used to transmit data from device I to device II, and the other optical
line is used to transmit data from device II to device I, for full-duplex
transmission.

Remember to connect the Tx (transmit) port of device I to the Rx (receive) port
of device II, and the Rx (receive) port of device I to the Tx (transmit) port of
device II. If you make your own cable, we suggest labeling the two sides of the
same line with the same letter (A-to-A and B-to-B, as shown below, or
A1-to-A2 and B1-to-B2).

ATTENTION

This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the Laser Beam.

Redundant Power Inputs

Both power inputs can be connected simultaneously to live AC/DC power
sources. If one power source fails, the other live source acts as a backup, and
automatically supplies all of the EDS’s power needs.

Alarm Contact

The Moxa EtherDevice Switch has one Alarm Contact located on the top panel.
For detailed instructions on how to connect the Alarm Contact power wires to
the two middle contacts of the 6-contact terminal block connector, see the

Wiring the Alarm Contact section on page 6. A typical scenario would be to

connect the Fault circuit to a warning light located in the control room. The
light can be set up to switch on when a fault is detected.

The Alarm Contact has two terminals that form a Fault circuit for connecting to
an alarm system. The two wires attached to the Fault contacts form an open
circuit when (1) EDS has lost power from one of the AC/DC power inputs, or
(2) one of the ports, for which the corresponding PORT ALARM DIP switch is
set to ON, is not properly connected.

If neither of these two conditions occurs, the Fault circuit will be closed.

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect the EDS’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, without paying
attention to the type of Ethernet cable being used for the connection. This
means that you can use either a straight-through cable or cross-over cable to
connect the EDS to Ethernet devices.

- 12 -

Triple Speed Functionality and
Switching

The EDS’s 10/100/1000 Mbps RJ45 switched port auto negotiates with the
connected device for the fastest data transmission rate supported by both
devices. The EDS is a plug-and-play device, so software configuration is not
required at installation or during maintenance.

The half/full duplex mode for the RJ45 switched ports is user dependent and
changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.

Auto-Negotiation and Speed Sensing

The EDS’s RJ45 Ethernet ports independently support auto-negotiation for
transmission speeds of 10 Mbps, 100 Mbps, and 1000 Mbps, with operation
according to the IEEE802.3 standard.

This means that some nodes could be operating at 10 Mbps, while at the same
time, other nodes are operating at 100 Mbps or 1000Mbps.

Auto-negotiation takes place when an RJ45 cable connection is made, and then
each time a LINK is enabled. The EDS advertises its capability for using 10
Mbps, 100 Mbps, or 1000 Mbps transmission speeds, with the device at the
other end of the cable expected to advertise similarly. Depending on what type
of device is connected, this will result in agreement to operate at a speed of 10
Mbps, 100 Mbps, or 1000 Mbps.

If an EDS’s RJ45 Ethernet port is connected to a non-negotiating device, it will
default to 10 Mbps speed and half-duplex mode, as required by the IEEE802.3
standard.
