About Cisco
Cisco's approach to quality can be condensed down to one phrase: "ensuring our customer success". The information contained in this section will help you to gain a better understanding of Cisco's Business Management System, which allows us to accomplish that success. Cisco's Business Management System is made up of two parts; the Quality Management System and the Environmental Management System.
Cisco Fun Facts
Cisco Systems, Inc. is an American multinational technology conglomerate headquartered in San Jose, California, in the center of Silicon Valley, that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, Jabber and Jasper, Cisco specializes into specific tech markets, such as Internet of Things (IoT), domain security and energy management.
Cisco is the largest networking company in the world. The stock was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index.
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, who pioneered the concept of a local area network (LAN) being used to connect geographically disparate computers over a multiprotocol router system. By the time the company went public in 1990, when it was listed on the NASDAQ, Cisco had a market capitalization of $224 million. Cisco was the most valuable company in the world by 2000, with a more than $500 billion market capitalization

Be the Expert: Power Over Ethernet
Technology is developing at a rate our ancestors would gawk at. Each day brings new patents, new inventions, new fads and new ideas to the forefront of the tech world. It's nearly impossible to keep up with every new development. That's why it's important to get back to basics and review traditional technology. Being an expert on important basics gives you a solid foundation to answer some of your customers' most important questions. All of that said, let's dive into the wonders of Power over Ethernet (PoE).What Is Power over Ethernet?
Before we get into some of the more technical aspects of Power over Ethernet (PoE), let's define it. PoE is simply a technology that carries electricity and data over network cables. That's it!But what does that mean practically? Let's break that down.
Let's say you're installing a security camera at a home or on the job. Most cameras normally require two connections: a power connection delivers power to the camera while a network connection delivers the camera's information to the recording / display setup connection. In a PoE connection, one cable transfers both power and data to and from the camera.
The Pros of PoE
There are a number of reasons to upgrade or install PoE cabling:- PoE saves time and money.Since you're installing one set of cabling instead of two, it'll take half the time and only a portion of the cost that installing both electrical and network cabling would.
- PoE is flexible. Since devices that use PoE don't tether to electrical outlets, you can install them virtually anywhere. That helps avoid messy, difficult tangles.
- PoE is safer than traditional wiring. PoE delivery protects equipment from electrical overload and under-powering. It even protects against incorrect installation!
- It's reliable. Since PoE power comes from a centralized source rather than random, outlying wall sockets, it backs up remotely and controls easily.
- It's scalable. This means that installation and distribution of connections throughout the network is simple but effective.
PoE Devices
While PoE integrates with a variety of different devices, a few are more common than others.- VoIP - Voice over Internet Protocol - phones are sort of the original PoE devices. These phones have a single connection, like other PoE devices, and power down remotely.
- As mentioned above, IP cameras are some of the most commonly used PoE devices due to the ease of installation and upkeep when they're combined with PoE cabling.
- Wireless Access Points are commonly designed to be PoE compatible so that they can be placed anywhere they're necessary.
Upgrading to PoE
Now that you know what PoE is, it's benefits and some of the most popular PoE devices, you need to know how to install or upgrade PoE. PoE switches are the most commonly used devices to bring PoE to an already existing network. However, PoE injectors are also an option for complicated systems that don't need to be rebuilt from the ground up.
