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.
6.0 mm
3.5 mm
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 on 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:
yUse 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.
yUse 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.
yKeep input wiring and output wiring separate.
yIt 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 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.
Relay
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:

Relay
1. A relay warning event is triggered.
OR
2. The EDS-405A/408A is the Master of this Turbo
Ring, and the Turbo Ring is broken.
OR
3. 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:
PWR1 PWR2
V1- V1+ V2- V2+
V1- V1+ V2- V2+
PWR1 PWR2
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 8, 6, or 5 10/100BaseT(X) Ethernet ports, and 0 (zero),
2, or 3 100BaseFX (SC/ST-type connector) fiber ports. EDS-405A models
have 5 or 3 10/100BaseT(X) Ethernet ports, and 0 (zero) or 2 100 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.

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 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.
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).

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) 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 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
EDS-405A/408A that can help setup the Turbo Ring easily within seconds. If
you do not want to use a hardware DIP switch to setup the Turbo Ring, you can
use a web browser, telnet, or console to disable this function.
NOTE Please refer to the Turbo Ring DIP Switch section and Using
Communication Redundancy section in User’s Manual for more

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 one will be the
Ring Master.
NOTE To switch on the Master or Coupler functions of the DIP switch,
you have to enable the Turbo Ring Pole first.
