Overview
The EDS-G205A-4PoE series industrial Ethernet switches are rugged
entry-level industrial 5-port gigabit PoE switches that support IEEE 802.3,
IEEE 802.3u, 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 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 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 use.

Mounting Dimensions (unit = mm)
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.

- 5 -
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 the 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
B
efore 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
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 electrica
l codes dictating the
m
aximum 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.
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.

- 7 -
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 EtherDevice Switch to the DC power
inputs, make sure the DC power source voltage is stable.
Communication Connections
The EDS-P205A-4PoE switches have 4 10/100/1000Base-T(X) PoE
Ethernet ports for connecting PoE devices, and 1 10/100/1000Base-T
port or 1 1000Base-X SFP slot for uplink connection.
10/100/1000Base-T(X) Ethernet Port Connection
10/100/1000Base-T(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.

PoE Ethernet Port Connection
PoE ports located on the EDS switch’s front panel are used to connect to
PoE-enabled devices. The pinout follows the Alternative A, MDI mode” of
802.3af/802.3at standards. Please see the details in the following table.

NOTE
According to IEEE 802.3af/at standards, the PD shall be
implemented to be insensitive to the polarity of the power supply
and shall be able to operate per MDI mode and MDI
-X mode.
However, some PDs only support MDI mode or MDI
-X mode only.
The following figure shows how to select the correct cable
between the PD and EDS-G205A-4POE.

RJ45 (8-pin) to RJ45 (8-pin) 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.
