A Quick Guide to PoE Switches
When you work in IT, PoE technology can be a real asset for your business. PoE switches like those offered by Cisco provide numerous ports that allow you and your users to charge up devices like network cameras, IP phones, wireless access points, and more quickly and easily. eBay offers a wide selection of Cisco PoE switches in a variety of styles and configurations so that you can find the right switch to enhance your business operation at a reasonable price.What is PoE?
Power over Ethernet (PoE) technology is used within wired Ethernet local area networks (LANs) to give the necessary electrical current needed to operate each device using data cables instead of power cords. Using PoE reduces the number of wires needed within the network. Created from the need to support devices and utilities like wireless access points, PoE makes installations easier and lends great flexibility.How do you select a PoE switch for your business?
With so many adequate network switches available, selecting the right switch to meet the needs of your business can be difficult. The following concepts may be helpful to you in narrowing down the search and helping you determine the right switch for your business.
- Form factor: Consider the layout of your work environment. If you want a quiet switch, desktop switches are good choices and take up little space. Other types of switches, like rack-mounted switches, are designed to be installed in wiring cabinets in a network room or data center.
- Network speed: Know your network speed or bandwidth. While many businesses still run on 10 megabits per second (Mbps), newer computers transfer data packets at 1000 Mbps, and that allows the physical connection between a device and switch to be as long as 328 feet long when using cable. Gigabit switches support all three speeds, 10/100/1000 Mbps, making it an ideal solution of all computer types.
- Ports: Know before you start shopping about how many ports you will potentially need. If you only had a few devices to power, you could make do with a switch offering up to 8 ports that fit into most budgets. If you have a growing business and want to be ready for potential expansion in the near future, you may want to consider a device with a higher number of ports.
