Hardware Installation Guide

Moxa EtherDevice Switch

Third Edition, April 2014

- 2 -

Overview

The EDS-G205 series is equipped with 5 Gigabit Ethernet ports, making it

an ideal and economical solution for demanding, high bandwidth Gigabit

Ethernet applications. In addition, the built-in relay warning function

alerts system administrators when power failures or port breaks occur.

The EDS-G205 series includes 2 models: one with an operating

temperature range of 0 to 60°C, and the other one with extended

operating temperature range of -40 to 75°C. These 2 models have passed

a 100% burn-in test to ensure that they fulfill the special needs of

industrial automation control. The EDS-G205 series can be easily

installed with DIN-Rail mounting as well as distribution boxes.

NOTE

Throughout this Hardware Installation Guide, we use EDS as an

abbreviation for Moxa EtherDevice Switch:

EDS = Moxa EtherDevice Switch

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

witch, with wall mount plates attached, as a guide

o 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.

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.

- 6 -

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 a

AELV source as defined in

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

- 7 -

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:

•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.

•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.

•Keep input wiring and output wiring separated.

•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.

- 8 -

FAULT: The two middle contacts of the

-contact terminal block connector

are used to

detect both power faults and port faults. The

two wires attached to the Fault contacts form

n open circuit when:

1. EDS has lost power from one of the DC

power inputs.

2. The PORT ALARM DIP switch for one of

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

connected properly.

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 DC

inputs. Top and front views of one of the terminal block connectors are

shown here.

STEP 1:

Insert the negative/positive DC

wires into the

V-/V+ terminals.

STEP 2:

To keep the 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 DC power inputs, make sure the

DC power source voltage is stable.

Communication Connections

EDS-G205 Models have 5 10/100/1000BaseT(X) Ethernet ports.

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.

- 9 -

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.

Redundant Power Inputs

Both power inputs can be connected simultaneously to live 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 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.

DIP Switch Settings

The default setting for each DIP switch is OFF.

The following table explains the effect of setting

the DIP switches to the ON positions.

DIP Switch

Setting

Description

BSP

Enables broadcast storm protection

OFF

Disables broadcast storm protection

----

refers to Jumbo

Frame

Enables jumbo frame function

OFF Disables jumbo frame function

PORT Alarm

Enables the corresponding PORT Alarm. If

the port’s link fails, the relay will form an

open circuit and the fault LED will light up.

OFF

Disables the corresponding PORT Alarm.

The relay will form a closed circuit and the

Fault LED will never light up.

ATTENTION

To actively update DIP switch settings, power off and then power

on the EDS.
