Overview
The EDS-2008-EL/ELP Series has an 8-port combination to simplify
network expansion. There are two housing types available for the user
to select depending on the requirements of their application. The ELP
has a plastic housing and the EL has a metal housing. The compact
switches provide a cost-effective solution for your industrial Ethernet
connection requirements.
The EDS-2008-EL/ELP Series provides 12/24/48 VDC (9.6 to 60 VDC)
power input, and the switches are available with a standard operating
temperature range from -10 to 60°C, or with a wide operating
temperature range from -40 to 75°C (only available for the –T models
in the EL Series). The switches are rugged enough to operate reliably in
harsh industrial environments.
To provide greater versatility for use with applications from different
industries, the EDS-2008-EL/ELP Series also allows users to enable or
disable broadcast storm protection (BSP), Quality of Service (QoS)
function via the DIP switches on the top panel.
The EDS-2008-EL/ELP switches can be easily installed with DIN-rail
mounting as well as distribution boxes. The DIN-rail mounting
capability and IP40 housing with LED indicators ensure that the plug-
and-play EDS-2008-EL/ELP switches are reliable and easy to use.

the EDS. Mount the EDS on the corrosion-free mounting rail that
adheres to the EN 60715 standard.
Suggested Installation Method
STEP 1:
Insert the upper lip of the DIN
-
rail kit into the mounting rail.
S
TEP 2:
Press the device towards the
mounting rail until it snaps into
place.
Alternatively, you can use
a screwdriver to attach to the
bottom of the DIN
-
rail kit and pull
down.
Suggested Removal Method
STEP 1:
Pull down the latch on the DIN
-
rail kit with a screwdriver.
STEP 2:
Slightly pull the device forward
and lift up to remove it from the
mounting rail.
NOTE
1. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment
may be impaired.
2.
The installation and the safety of any system incorporating
the equipment is the responsibility of the assembler of the
system.
3.
This is an OPEN TYPE module and should be installed in a
safety enclosure with mechanical rigidity and an
appropriate IP rating.

Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS on the
wall, as illustrated below.
There are two options for installation: The first option
is to h
ook the EDS DIN-rail latch on the opening of
the
wall mount kit (see picture above) and then
m
ount the wall-mount kit on the wall with screws.
(The other option is to perform these two steps in
the other order.)
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 th
e 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.
Once the screws are fixed in the
wall, insert the
two screw heads
through the large parts of the
keyhole
-shaped apertures, and
then slide EDS downwards, as
indicated. Tighten the
two
screws for added stability.
WARNING
External metal parts are hot. Take necessary precautions if it is
necessary to touch.

Wiring Requirements
WARNING
Do not disconnect modules or wires
unless the power supply
has been switched off or the area is known to be non
-
hazardous.
The devices may only be connected to the supply
voltage shown on the type plate.
The devices are designed for operation with a
Safety Extra-L
ow
V
oltage. Thus, they may only be connected to the supply
voltage connections and to the signal contact with the
Safety
E
xtra-Low Voltages (SELV) in compliance with IEC950/
EN60950/ VDE0805.
WARNING
Safety First!
Be sure to
disconnect the power cord before installing and/or
wiring your
Moxa EtherDevice Switch.
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 t
he 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 that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring to 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.
A 4 mm2conductor must be used when a connection to the external
grounding screw is utilized.

- 11 -
ATTENTION
This product is intended to be mounted to a well
-grounded
mounting surface, such as a metal panel.
Wiring the Power Input
The top two contacts and the bottom two contacts of the 2 or 3 contact
terminal block connector on the EDS’s top panel are used for the EDS’s
two 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 the EDS’s top panel.
NOTE
The power source comes from secondary circuits. These circuits
are separated from mains circuits by a transformer in which the
primary windings are separated from the secondary windings
by reinforced installation, double installation, or a screen
connected to the protective conductor terminal.
ATTENTION
Before connecting
the EDS to the DC power inputs, make sure
the DC power source voltage is stable.
ATTENTION
One individual conductor in a clamping point with 28
-14 AWG
wire size, and a torque value of 1.7 lb-in should be used.
Communication Connections
The EDS-2008-EL/ELP models have 10/100BaseT(X) Ethernet ports and
100BaseFX Ethernet ports.

10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS’s front panel are used to
connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward.
Suppose you are connecting devices I and II. As opposed to 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 transmit data
from device II to device I, for full-duplex transmission.
All you need to remember is 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 are making 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 by the following illustration,
or A1-to-A2 and B1-to-B2).

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the EDS’s
10/100BaseT(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.
Dual Speed Functionality and Switching
The EDS’s 10/100 Mbps RJ45 switch 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.
Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is
made to either filter or forward the packet. Packets with source and
destination addresses belonging to the same port segment will be
filtered, constraining those packets to one port, and relieving the rest of
the network from the need to process them. A packet with a destination
address on another port segment will be forwarded to the appropriate
port, and will not be sent to the other ports where it is not needed.
Packets that are used in maintaining the operation of the network (such
as the occasional multi-cast packet) are forwarded to all ports. The EDS
operates in the store-and-forward switching mode, which eliminates
bad packets and enables peak performance to be achieved when there
is heavy traffic on the network.

- 15 -
Switching and Address Learning
The Moxa EDS has an address table that can hold up to 8,000 node
addresses, which makes it suitable for use with large networks. The
address tables are self-learning, so that as nodes are added or
removed, or moved from one segment to another, EDS automatically
keeps up with new node locations. An address-aging algorithm causes
the least-used addresses to be deleted in favor of newer, more
frequently used addresses. To reset the address buffer, power down the
unit and then power it back up.
Auto-Negotiation and Speed Sensing
The EDS’s RJ45 Ethernet ports independently support auto-negotiation
for transmission speeds of 10 Mbps or 100 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.
When an RJ45 cable is connected, auto-negotiation takes place, and
then each time a LINK is enabled. The EDS advertises its capability for
using 10 Mbps or 100 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 or 100 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.
