FIRST INDUSTRIAL POWER OVER ETHERNET SWITCH ADDRESSES
CHICKEN/EGG QUESTION, OPENS MARKET FOR PoE APPLICATIONS

Implementation Costs for Devices such as Surveillance Cameras
and Remote IP Phones Can Be Reduced - Even in Hostile Environments
- Using PS14P PoE Switch

GarrettCom™, Inc., is bringing the flexibility and cost-savings
benefits of Power-over-Ethernet (PoE) to industrial applications with
the introduction of its four-port Magnum™ PS14P PoE Power Source
Convenient Switch. The hardened PS14P switch is the first
industrial-spec switch to offer an IEEE 802.3af standards-compliant way
to power and connect small devices such as IP phones, surveillance
cameras, wireless access points and industrial sensors at the remote
edges of an industrial network. The PS14P switch is premium-rated for
temperature-uncontrolled environments with a temperature rating of
-40°C to 75°C, and resists dirt, moisture, and other threats from
hostile industrial environments.
Originally developed to provide an inexpensive power source for VoIP
phones being deployed in enterprises, PoE (IEEE 802.3af), enables Power
Sourcing Equipment (PSE) to provide power over standard twisted-pair
Ethernet cabling to a compliant Powered Device (PD). PDs use PoE
standard protocols to - and utilize - power transmitted over the
data link. In effect, PoE provides a standards-based way to provide
power to a wide variety of PDs in areas where it is physically or
financially prohibitive to offer normal power.

Many Enterprise Ethernet applications are utilizing a device called a
"Midspan Power Source" to "inject" power into an existing
network. This box sits between an existing Ethernet switch and the
target PDs. By integrating Ethernet switching, PoE power sourcing, and
industrial-hardened components and packaging into a single unit,
GarrettCom's Magnum PS14P PoE Power Source Convenient Switch saves
costs and space, and increases reliability in a wide spectrum of
industrial applications. As more new industrial PoE devices arrive in
the market, the Magnum PS14P Switch will also enable new applications,
extending Ethernet LANs further into high-availability industrial
systems.

GarrettCom is at the forefront of bringing this much-needed technology
to the industrial environment," said Norman Pearl, VP of Engineering,
Dataradio Inc., Montreal, Quebec. We plan on deploying the PS14P
switches with our spread-spectrum, license-free HiPR900 radio system
that is used in SCADA and telemetry industrial applications.
GarrettCom's PoE implementation gives us plug-and-play solutions with
minimal complexity, while the small package makes it ideal for remote
substations, and other locations with limited available real estate.

The Magnum PS14P Switch has four PoE-enabled RJ-45 ports that can drive
802.3af-compliant PDs as well as deliver 10/100 Mb data transmission
over the same twisted-pair cable. The PS14P switches have an
auto-sensing algorithm that cuts off power when 802.3af-compliant
devices are not attached.Proprietary PoE and non-PoE equipment are not
recognized, which protects them from possible damage. The PS14P switch
supports the Power-over-Ethernet PSE standard for over-current
protection, under-current detection, and fault protection.

Built to Take the Heat

The Magnum PS14P Switch, about the size of a deck of playing cards, is
only 3.5 in x 3.0 in. x 1.0 in. ( (8.9 cm x 7.6 cm x 2.5 cm), and
weighs 5.2 oz. (150 g).Its four PoE RJ-45 ports can be supplemented by
connecting the switch to a Magnum CS14P Converter Switch™ device or a
Magnum ES42P Edge Switch to obtain fiber connectivity or additional
non-PoE hardened Ethernet ports.

The PS14P models are built with premium-grade extended temperature
components to be suitable for use in sheltered outdoor locations. It
uses GarrettCom's patent-pending thermal techniques and is equipped
with a robust metal case for durability. Mounting options include
stand-alone panel-mounting, DIN-rail, or rack-mount tray. No internal
air flow is required for cooling, so the PS14P resists dust, dirt,
moisture, smoke and insects.The Magnum PS14P PoE Power Source
Convenient Switch and all other Magnum products are designed and
manufactured in the USA and backed by a three-year warranty.
