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

MOXA provides a complete end-to-end solution for any IEEE 802.3af PoE
compliant unit and Ethernet-enabled device. The EDS-P308 and SPL-24 can
be used to simplify wiring in the field, and provide a more versatile

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:

y 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.

y 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.

y 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.

y Keep input wiring and output wiring separated.
y It is strongly advised that you label wiring to all devices in the system when

necessary.
