Overview
The EDS-G205A-4PoE series industrial Ethernet switches are rugged
entry-level industrial 5-port Gigabit PoE switches for environments that
fall under the pollution degree 2 category. The industrial Ethernet
switches support IEEE 802.3, IEEE 802.3u, and IEEE 802.3x with
10/100/1000M, full/half-duplex, MDI/MDIX auto-sensing, and IEEE
802.3af/IEEE 802.3at PoE standards.
The EDS-G205A-4PoE series provides 12/24/48 VDC redundant power
inputs that can be connected simultaneously to a live DC power source.
The switches are available with a standard operating temperature range
from 0 to 60°C, or with a wide operating temperature range from -40 to
75°C, and their IP30 metal housing makes them rugged enough for any
harsh industrial environment.
To provide greater versatility for use with applications from different
industries, the EDS-G205A-4PoE switches also allow users to enable or
disable broadcast storm protection, 802.3az, Jumbo frame, and PoE high
power with DIP switches on the outer panel. The EDS-G205A-4PoE
switches can be easily installed on a DIN-Rail or in distribution boxes. The
DIN-Rail mounting capability and IP30 metal housing with LED indicators
make the plug-and-play EDS-G205A-4PoE switches reliable and easy to

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 m
etal spring.
STEP 2: The DIN-Rail attachment
unit will snap into place as shown
below.
To remove the EDS from the DIN-rail, simply reverse Steps 1 and 2
above.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the
EDS-G205A-4PoE on a wall, as shown in the following figures.
STEP 1:
Remove the aluminum
DIN
-rail attachment plate
from
the EDS-G205A-
4PoE’s
rear panel, and then attach
the wall mount plates as
shown
in the diagram at
the
right.
STEP 2:
Mounting
the EDS-G205A-
4PoE 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.
NOTE
Before tightening the 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 completely—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 on 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
correct
power supply voltage is listed on the product label. Check
the voltage of your power source to make sure that you are using
the correct voltage. Do NOT use a voltage greater than what is
specified on the product label
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 points:
•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.
•Please use copper conductor only.

Grounding the 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 Redundant Power Inputs
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 front views 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.
ATTENTION
Before connecting the EtherDevice Switch to the DC power
inputs,
make sure the DC power source voltage is stable and
the
DC power source is supplied by UL Listed Isolated Power Supply.
Communication Connections
The EDS-G205A-4PoE switches have 4 10/100/1000Base-T(X) PoE
Ethernet ports for connecting PoE devices, and 1 10/100/1000BaseT port
or 1 100/1000BaseX SFP slot for uplink connection. For fiber connections,
a field installed optical transceiver must be UL Recognized, in the Class I
category, and contain the following CDRH Certification Marking:
‘Complies with 21CFR 1040.10 and 1040.11’.
10/100/1000BaseT(X) Ethernet Port Connection
10/100/1000BaseT(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.

RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
NOTE
If the PD only supports PoE MDI mode (V+, V+, V-, V- for pins 1,
2, 3, 6), choose a cross
-over Ethernet cable to connect the PD
and the EDS switch. If the PD only supports PoE MDI
-X mode (V-
,
V
-, V+, V+ for pins 1, 2, 3, 6), choose a straight-through
Ethernet cable between the PD and the EDS switch.
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.
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.

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
needing to pay 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.

- 11 -
Triple Speed Functionality and Switching
The Moxa EtherDevice Switch’s 10/100/1000 Mbps switched RJ45 port
auto negotiates with the connected device for the fastest data
transmission rate supported by both devices. All models of Moxa
EtherDevice Switch are plug-and-play devices, so that software
configuration is not required at installation, or during maintenance. The
half/full duplex mode for the switched RJ45 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.
Jumbo Frame
The EDS-G205A-4PoE series supports Ethernet jumbo frames up to 10k,
which is with more than 1500 bytes of payload. This function is by default
disabled and can be enabled by turning on the DIP switch labeled “Jumbo”
on the top cover. This is commonly used for large packet size applications
such as video surveillance.
Broadcast Storm Protection
The EDS-G205A-4PoE Series has a built-in algorithm for limiting the
amount of broadcast packets through the switch. This function is by
default disabled and can be enabled by turning on the DIP switch labeled
“BSP” on the top cover. If the broadcast storm protection algorithm
detects more than 2k broadcast frames per second, then the switch will
be suppressed from receiving broadcast frames for a period of 2 ms to
prevent any further flooding.
Total Power Budget
For the total power budget, the EDS-G205A-4PoE will provide 62 W at 12
to 17 VDC input, 120 W at 18 to 35 VDC input, and 144 W at 36 to 57 VDC
input. The total power budget is the total amount of reserved PoE power
based on the PoE class of the PoE device. If a newly connected PoE device
causes the total reserved power to exceed the total power budget, the
newly connected PoE device will be denied power.
