Overview
We describe two products in this manual:
The MOXA EtherDevice™ EDS-P308 is an 8-port smart Ethernet switch
that provides an economical solution for your Ethernet connections. The
switch supports PoE (Power-over-Ethernet) on ports 1 to 4, which means that
the EDS-P308 can double as a piece of power source equipment (PSE). When
used in this way, the EDS-P308 can supply up to 15.4 watts of power per port,
and can power IEEE 802.3af compliant powered devices (PD), eliminating
the need for additional wiring. As an added bonus, the built-in smart alarm
function helps system maintainers monitor the health of your Ethernet
network.
The SPL-24 plays the role of PD, and splits the data signal and power signal
that are transmitted from the PSE. The SPL-24 plays a dual role of providing
power to industrial devices, and enabling Ethernet connections.
The EDS-P308 and SPL-24 have a wide operating temperature range of -40 to
75°C, and are designed to withstand a high degree of vibration and shock. The
rugged hardware design makes the EDS-P308 and SPL-24 perfect for
ensuring that your Ethernet equipment can operate in critical industrial
environments, such as in hazardous locations, and complies with FCC and CE
standards.
The installation of the EDS-P308 is presented on pages 3 to 10. The
installation of the SPL-24 is presented on pages 11 to 14.
NOTE Throughout this Hardware Installation Guide, we use EDS as an
abbreviation for MOXA EtherDevice Switch, and we use SPL as
an abbreviation for MOXA PoE Splitter:
EDS = MOXA EtherDevice Switch
SPL = MOXA PoE Splitter

environment for installing devices. PoE technology lets you eliminate the
need for using power outlets to deploy Ethernet-enabled devices—such as a
wireless access point (AP) or an IP camera—on a ceiling or outdoors. The
devices can be placed up to 328 feet (100 m) from a PSE.
Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has
been switched off or the area is known to be non-hazardous. The
devices may only be connected to the supply voltage shown on
the type plate.
The devices are designed for operation with a Safety Extra-Low
Voltage. Thus, they may only be connected to the supply voltage
connections and to the signal contact with the Safety Extra-Low
Voltages (SELV) in compliance with IEC950/ EN60950/
VDE0805.
WARNING
The power for this product is intended to be supplied by a Listed
Power Unit, with output marked LPS, and rated to deliver 48
VDC at a maximum of 300 mA.
WARNING
This unit is a built-in type. When the unit is installed in another
piece of equipment, the equipment enclosing the unit must
comply with fire enclosure regulation IEC 60950/EN60950 (or
similar regulation).
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.
You should also pay attention to the following items:
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.
yNOTE: 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.
yYou 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.
yKeep input wiring and output wiring separated.
yIt is strongly advised that you label wiring to all devices in the system when
necessary.

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.

Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS-P308 on the
wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN-Rail attachment plate
from the EDS-P308’s rear
panel, and then attach the
wall mount plates, as shown
in the diagram below.
⇒

STEP 2:
Mounting the EDS-P308 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 all the way—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-P308 downwards, as
indicated. Tighten the four screws
for added stability.
⇒
Grounding the EDS-P308
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.

EDS-P308’s 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 EDS-P308’s power needs.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact terminal
block connector on EDS’s top panel are used for EDS’s two DC inputs. Top
and front views of one of the terminal block connectors are shown here.
Top View
Front View
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 EDS to the DC power inputs, make sure the
DC power source voltage is stable.
EDS-P308’s Alarm Contact
The EDS-P308 has one alarm contact located on its top panel. For detailed
instructions on how to connect the alarm contact power wires to the two middle
contacts of the 6-contact terminal block connector, see the Wiring the Alarm
Contact section on page 9. 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 alarm 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) EDS has lost power from one of the DC power inputs, or (2)
one of the ports for which the corresponding PORT ALARM DIP Switch is set
to ON is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.

ON DIP
ON: Enables the corresponding PORT Alarm. If
the port’s link fails, the relay will form an
open circuit and the fault LED will light up.
Off: Disables the corresponding PORT Alarm.
The relay will form a closed circuit and the
Fault LED will never light up.
Wiring the Alarm Contact
The alarm contact consists of the two middle contacts of the terminal block on
EDS’s top panel. Refer to page 8 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
FAULT
Top View
Front View
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:
1. EDS has lost power from one of the DC
power inputs.
OR
2. One of the ports for which the corresponding
PORT ALARM DIP Switch is set to ON is
not properly connected.
If neither of these two conditions is satisfied, the
Fault circuit will be closed.
