Mounting Dimensions unit = mm (in)
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 y ou need to
reattach the DIN-rail attachment plate, make sure the metal spring is
situated towards the top, as shown in the figures below.
STEP 1:
Insert the top of the DIN
the slot just below the metal spring.
-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 o n 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

EDS on the wall requires 4 screws. Use the
s
witch, with wall mount plates attached, as a guide to
mark the correct locations of the 4 screws. Th e heads of
the screws should be less than 6.0 mm in dia meter, and
the shafts should be less than
shown in the figure at the right.
Before tightening screws into the wall, make s ure the screw head
and shank size are suitable by inserting the scr ew into one of the
keyhole-shaped apertures of the wall mounting plates.
Do not tighten the screws all the way in — 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 four
screw heads through the
large parts of the
keyhole
and then slide the EDS
downwards, as indicated.
Tighten the four screws for
added
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 s ure you are using th e
correct voltage. Do NOT use a voltage greater than
specified on the product label.
These devices mus t be supplied by an AELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.
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 w iring 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 communicat ions 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 k ept separat e. The ru le of thumb is
that wiring with similar electrical characteristics can be bundled
together.
• Keep input wiring and output wiring separated.
• It is strongly adv ised that you label wiring for all devices in the system
when necessary.
Grounding the Moxa EtherDevice Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the groun d connect ion from th e
ground screw to the grounding surface prior to connecting devices.
This product is intended to be mounted to a well
mounting surface, such as a metal panel.
Wiring the Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fa ils, the other live source act s as a backup,
and automatically supplies the EDS-210A with power.
The two 2-contact terminal block connectors on the EDS's top panel are
used for the EDS's two DC power inputs. Top and fron t view of the
terminal block connectors are shown here.
Step 1: Insert the negative/p o s it iv e DC wire s int o th e
V
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.
Insert the plastic terminal block connector
prongs into the terminal block receptor, which is located
on
Before connecting the EDS
-210A to the DC power inputs, make
sure the DC power source voltage is stable.

Communication Connections
EDS-210A models have 10/100BaseT(X) Ethernet ports,
10/100/1000BaseT(X) Ethernet ports,100BaseSFP and 1000BaseSFP.
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 devi ces .
Next, we show pinouts for both MDI (NIC-type) po rts a nd MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.
RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring
RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
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 d epending 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 the following section, 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-210A series are SFP type slots, which support
both 100Base-FX and 1000Base-X speed fiber transceiver to work
properly. Moxa provides complet e transceiver models for various distance
requirements.

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 (tra nsmit) port of device I to the Rx (r eceive)
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).

Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If on e power source fa ils, the other live source acts as a backup,
and automatically supplies all of the EDS’s power needs.

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.
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 trans mission rate supp orted 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.

- 11 -
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 th e
same time, other nodes are opera ting at 100 Mbps or 1000 Mbps.
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 t he cable expected t o 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 connect ed to a no n-negotiatin g device,
it will default to 10 Mbps speed and half-duplex mode, as required by the
IEEE802.3 standard.
