Mounting Dimensions (unit = mm)
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of the EDS-405A/408A 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 following figures.
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.
To remove the Moxa EtherDevice switch from the DIN-Rail, simply
reverse Steps 1 and 2.

- 8 -
Wall Mounting (optional)
For some applications, you will find it convenient to mount the
EDS-405A/408A on the wall, as shown in the following figures.
STEP 1:
Remove the aluminum
DIN-Rail attachment plate
from the EDS-405A/408A’s
rear panel, and then attach
the wall mount plates with
M3 screws, as shown in the
diagram at the right.
⇒
STEP 2:
Mounting the EDS-405A/408A 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.
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-405A/408A downwards, as indicated. Tighten the four screws for
added stability.

Wiring Requirements
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 the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.
Be sure to read and follow these important guidelines:
•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
through the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
•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 separate.
•When necessary, you should label the wiring to all devices in the
system.
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 Relay Contact
The Relay Contact consists of the two middle contacts of the terminal
block on the EDS-405A/408A’s top panel. 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.
FAULT: The two middle contacts of the 6-contact
terminal block connector are used to detect both
power faults and port faults. The two wires
attached to the fault contacts form an open
circuit
when:

- 10 -
A relay warning event is triggered.
OR
The EDS-405A/408A is the Master of this Turbo
Ring, and the Turbo Ring is broken.
OR
There is a start-up failure.
If none of these three conditions is satisfied, the
fault circuit will remain 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-405A/408A’s top panel are used for
the EDS-405A/408A’s two DC inputs. Top and front views of one of the
terminal block connectors are shown in the following figures:
STEP 1: Insert the negative/positive DC wires into
the V-/V+ terminals, respectively.
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-405A/408A’s top
panel.
ATTENTION
Before connecting the EDS-405A/408A to the DC power inputs,
make sure the DC power source voltage is stable.
Communication Connections
EDS-408A models have 5, 6, or 8 10/100BaseT(X) Ethernet ports, and 3,
2, or 0 (zero) 100BaseFX (SC/ST-type connector) fiber ports. EDS-405A
models have 3 or 5 10/100BaseT(X) Ethernet ports, and 2 or 0 (zero) 100
BaseFX (SC/ST-type connector) fiber 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.
Next, 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.

Wiring
RJ45 (8-pin) to RJ45 (8-pin) Cross-over Cable Wiring
100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward.
Suppose you are connecting devices I and II; contrary 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 fromdevice
I to device II, and the other optical line is used transmit data from device
II to device I, for full-duplex transmission.
Remember 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 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).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the laser beam.
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 the EDS-405A/408A with power.
Relay Contact
The Moxa EtherDevice switch has one relay contact located on the top
panel. For detailed instructions on how to connect the relay contact power
wires to the two middle contacts of the 6-contact terminal block
connector, see the Wiring the Relay Contact section. 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 relay 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) a relay warning event is triggered, (2) the
EDS-405A/408A is the Master of this Turbo Ring, and the Turbo Ring is
broken, or (3) there is a start-up failure. If none of these three conditions
occur, the fault circuit will be closed.
Turbo Ring DIP Switch Settings
EDS-405A/408A series switches are plug-and-play managed redundant
Ethernet switches. The proprietary Turbo Ring protocol was developed by
Moxa to provide better network reliability and faster recovery time. Moxa
Turbo Ring’s recovery time is less than 300 ms (Turbo Ring) or 20 ms
(Turbo Ring V2) —compared to a 3 to 5-minute recovery time for
commercial switches—decreasing the possible loss caused by network
failures in an industrial setting.
There are 4 Hardware DIP Switches for Turbo Ring on the top panel of the
EDS-405A/408A that can be used to set up the Turbo Ring easily within
seconds. If you do not want to use a hardware DIP switch to set up Turbo
Ring, you can use a web browser, Telnet, or console to disable this
function.
NOTE Refer to the Turbo Ring DIP Switch section and Using
Communication Redundancy section in the user’s manual for
detailed information about the settings and usage of Turbo Ring
and Turbo Ring V2.

NOTE If you do not enable any of the EDS-405A/408A switches to be
the Ring Master, the Turbo Ring protocol will automatically
choose the EDS-405A/408A with the smallest MAC address range
to be the Ring Master. If you accidentally enable more than one
EDS-405A/408A to be the Ring Master, these EDS-405A/408A
switches will auto-negotiate to determine which switch
will be the
Ring Master.
NOTE To switch on the Master or Coupler functions of the DIP switch,
you need to enable the Turbo Ring Pole first.
