SLM2048T-EU SG200-50 50-port Gigabit Smart Switch
The 200 Series Small Business SG200-50 Ethernet Smart Switch from Cisco is an Ethernet network switch designed to give you better management, security, and quality of service features than an unmanaged or consumer-grade switch at a lower cost than a managed switch. This particular switch features a total of 50 Gigabit Ethernet ports; however, two of those ports are a combination of RJ-45 Gigabit Ethernet and mini Gigabit Interface Converter (mini-GBIC) expansion slots. With those expansions slots, you have the option to add fiber optic or Gigabit Ethernet uplink connectivity to the switch.

In addition to these ports, the switch includes Quality of Service features that allow you to prioritize latency-sensitive applications, such as IP telephony or video surveillance. The switch also provides native support for both IPv4 and IPv6, which allows you to take advantage of the latter protocol as it becomes more prevalent and widespread in the future. So as to safeguard your network, the switch utilizes IEEE 802.1X port security to control access to your network and reduce the risk of a security breach. 

In setting up the switch, it can discover all connected Cisco devices on your network, share info between these devices, and also give you information, such as Serial numbers, IP addresses, and the like for quick deployments. Designed to be power-efficient, the switch can reduce the amount of power to any port when that port isn't being used and will reduce the power it sends through an Ethernet cable when it detects that the cable is short.
Easy Configuration and Management
This switch is designed to be easy to deploy and use by small businesses or the partners that serve them. Simple-to-use web-based interfaces reduce the time it takes to deploy, manage, and troubleshoot your network
·Cisco Discovery Protocol simplifies setup by discovering all connected Cisco devices and allowing them to share information 
·Cisco FindIT Network Discovery Utility works through a simple toolbar on the user's web browser to discover Cisco devices on the network and display basic information, such as serial numbers and IP addresses, to aid in the configuration and speed the deployment of Cisco Small Business products
Performance and Reliability
This switch has been tested to deliver the high availability and performance you would expect from a Cisco switch and help you prevent costly downtime. This switch can speed up file transfer times, improve slow and sluggish networks, keep your vital business applications available, and help your employees respond more quickly to customers and each other. With a network based on this or other Cisco 200 Series switches, you can address all of your business communication and connectivity needs and reduce the total cost of ownership of your technology infrastructure
Network Security
This switch provides the basic security and network management features that you need to maintain a level of security for your business, keep unauthorized users off the network, and protect your business data. The switch provides integrated security to reduce the risk of a security breach, with IEEE 802.1X port security to control access to your network
IP Telephony Support
This switch includes Quality of Service (QoS) features to prioritize delay-sensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services. For example, Auto Voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic
IPv6 Support
This and other Cisco 200 Series switches provide native support for IPv6 alongside traditional IPv4. That means you can take full advantage of IPv6-enabled operating systems and applications in the future, without having to upgrade your network equipment
An Energy-Efficient Solution
This switch is designed to be eco-friendly without compromising performance. They help conserve energy by optimizing power use, which helps protect the environment and lowers your energy costs. Power-saving features include the following: 
·Automatic power down on Gigabit ports when a link is not active
·Embedded intelligence to adjust power based on cable length
Additional Gigabit Ethernet Ports
The switch features a total of 50 Gigabit Ethernet ports, two of which are also mini-Gigabit Interface Converter (mini-GBIC) expansion slots that give you the option to add fiber optic or Gigabit Ethernet uplink connectivity to the switch. With the ability to increase the connectivity range of your switch, you have more flexibility to design your network around your unique business environment, and to easily connect switches on different floors or across the business.
