Industrial Power Over Ethernet (PoE) Switch by GarrettCom, Inc.

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.

Which brings up a nagging question:

How can Linksys build POE gear, including 802.11af power injectors and

5V or 12V endpoint power extractors, for under $50 a pair, while everyone else's POE gear is on the order of $100/port for just the injector (10/100 switch ports are essentially free to a first approximation in this case, IMHO).

Perhaps you should be asking why everyone else is $100 per port. Maybe there's no justification for that price. This sort of thing has been happening for years. Initially the price is high, but someone then drives it down. This might be one such instance.

Magnum products from GarrettCom are hardened for industrial and outdoor applications such as video surveillance. The PS14P PoE Switch is a specialty item for stressful applications, not a commodity product.

I agree with you. PoE is a hot technology, and everybody is trying to reap the most profits while they can. In terms of design, circuitry, amount of ICs and overall complexity a PoE-enables Ethernet switch is only marginally higher than a regular one. If you are able to buy a 5-port Ethernet switch for $30 today, I do not see why you wouldn?t be able to buy a PoE-enabled 5-port switch for $50 as soon as the market saturates enough.

Cheers!

My point exactly. There _is_ about $15 worth of additional power supply, so I'd happily pay $20-$25 per port extra, but $100/port is way too much.

I just bought the last of

$26.46, though I haven't had a chance to try it out yet. I've also got a couple of the Linksys 5V and 12V kits, so as soon as my Round Tuit arrives I can start fiddling... 8*)

Now if Phihong would make an 8-port version for $150...

I now have a five port gigabit switch I got at Fry's on sale for $30.

No PoE, though. It has to get popular enough to make the economy of scale work, and I don't believe that is true yet.

How much extra should the actual power supply cost?

Somewhere on the order of a buck a watt, or $15 for the power supply, and another few dollars for the PoE chipset, IMNSHO.

Yes, sorry, my numbers were 'per port'.

isnt PoE 15 watts per port?

so $75 on your 5 port switch

Hardened in what way?

Why? If you're going to spam this newsgroup you should answer in it.

Not everyone needs 'industrial strength' PoE solutions, so it's an interesting product to a small subset of the market.

It's not clear if it comes with a power supply, though, which could add a few bucks.

Why would the power supply cost $1/watt? PC power supplies typically go around 20 cents a watt or so, with multiple output voltages.

Because it's not a PC supply made in the bazillions, but a (somewhat custom) 48V supply made for a specific purpose, with far less volume and (as of now) very little competition. When PoE gets popular and everyone has dozens of PoE peripherals in their house, it'll be a lot less, but at this point, random power supplies (and other power electronics, like inverters, battery chargers, solar grid-tie boxes, etc) are on the order of a buck a watt.
