The History of PoE (Power over Ethernet)

Tuesday, June 16th, 2009

PoE, or Power over Ethernet, is a technology that describes a system to transfer both electrical power and data to remove devices using standard twisted-pair cable in an Ethernet network. In many circumstances, supplying power separately is infeasible, expensive, or just plain inconvenient, and a switch module that offers PoE enhances a network’s versatility and makes it more attractive to network administrators. A good comparison is POTS telephones. Like a network with PoE, POTS telephones are analog, but receiver data and power through the same cable. You may also hear PoE referred to as ‘inline power.’

Power over Ethernet is useful for powering embedded computers,wireless LAN access points,IP telephones, remote network switches, and network cameras as well as other I.T. hardware that needs power. PoE is typically implemented following the specification guidelines in IEEE std. 802.3af-2003.

Industry leader Cisco Systems is the father of original PoE equipment. Cisco was manufacturing components with inline power several years before an IEEE standard for delivering PoE came to be. With a capability of delivering up to 10 Watts per port, Cisco PoE forerunners ensured the amount of power to be delivered was negotiated between the endpoint and the Cisco switch. This was based on a power value added to the CDP, or Cisco proprietary Cisco Discovery Protocol. But CDP does even more. It’s responsible for communicating the Voice VLAN value from the Cisco switch to the Cisco IP Phone as well.

Now, you will find many products on the market that offer PoE. Cisco is still providing hardware on the cutting edge of this technology with products like PWR-C45-1300ACV and PWR-C45-4200ACV.

Don’t Spend More than You Need when You’re Starting Up

Monday, January 5th, 2009

When we first set up the company, we really didn’t know what our needs were going to be.  Would we be wildly successful or would we fail in our first year?  Not knowing makes it difficult to plan and we didn’t want to buy a bunch of computer hardware and telephone systems that were way beyond our reach.  We didn’t have the money.  Luckily, we went with the Cisco Unified IP Phones 797XG/GE.  We thought it would be best to start small and then expand if the time ever came to do so.  Thank goodness it did.

Last week, we purchased the Cisco Unified IP Phone Expansion Module 7914 which extends the capabilities of the phone system we already had (apparently it also works with the Cisco Unified IP Phones 79GXG/G-GE) by adding fourteen buttons and an LCD display.  The best thing about adding the expansion module is that we could choose which phones actually needed it (our part-time bookkeeper didn’t need it at all), so we again, we had control over how much we spent and weren’t put in a position to buy a bunch of fancy stuff we didn’t need.

Long story short, my advice to new business owners is to look at IT hardware purchases realistically.  While it’s always nice to dream about where you want to be once you’ve increased sales and started to grow, the reality of now is more important.  And mistakes you make now (like wasting money on an architecture that handles way more than your current needs entail) can make or break you in your first year.  Be smart.  Upgrading later on isn’t as difficult as you’d imagine it is and some companies even offer refurbished equipment at huge discounts making the upgrade down the road easy and affordable—should you get there.  And I hope you do.

Cisco’s Quality Carries Through to Refurbished Gear

Tuesday, December 9th, 2008

If you’re in the market for IT hardware, then you’ve probably seen plenty of support for Cisco Systems, the industry leader in data center, telephony, network systems, security, and unified communications solutions.  With as many as 14 billion devices projected to be connected to the Internet by 2010, a company’s success and longevity depends on the right networking systems and hardware.  With Cisco’s revenue at $39.5 billion at the end of the 2008 Fiscal year, it’s easy to see why Cisco is the worldwide leader.

But Cisco has not relied only in innovation and marketing.  One of the reasons that Cisco leapt ahead of competitors has to do with the high quality equipment it manufactures.  Since the company’s inception in 1984, Cisco products have consistently been praised by reviewers and customers for their top-of-the-line quality. They’ve truly created a company that stands behind their products and built a reputation based on reliability.

The downside to purchasing IT hardware like routers and telephone systems from Cisco, is that you do get what you pay for and Cisco products are not cheap.  As a matter of fact, often small and growing businesses simply cannot afford to upgrade their IT hardware as often as they really need to in order to accommodate their expansion.  That’s where refurbished Cisco products come in.

Because Cisco hardware holds its value much longer than many of its competitors, refurbished Cisco products are, most of the time, hold their quality.  This is evident in the number of alternate Cisco providers that have cropped up, eager to refurbish and resell Cisco products at discounted prices.  The important factors when choosing one of these alternate Cisco distributors are to be sure the company has been around for a considerable length of time and proven that they, too, are reliable.  Make sure the company you buy your used Cisco hardware from allows you to speak to someone on the phone (a website that does not advertise a phone number so that you can reach a rep easily usually spells trouble).  Also be sure that the company offers a guarantee on the products they sell.  For example, one alternate Cisco provider, MULTI-LINK Communications Products, offers a one year standard warranty on all refurbished and new equipment.  This is actually four times longer than the warranty Cisco offers on most of its new products.  Lastly, you want to make sure that the company you order from has a large inventory of Cisco hardware.  Some of the smaller companies sell you a product and then have to go hunt it down which means guaranteeing you a delivery time can be next to impossible.
