Cisco, one of the world's largest network equipment companies, has an entire line of CBS250 managed switches that are designed for businesses with basic networking needs. They can be used to reduce network infrastructure costs in cases where no complex configuration is required. For example, in video surveillance networks, server management, thin clients and a large number of other similar devices deployed compactly on a single subnet.
The Cisco Business CBS250-16P-2G-EU switch is an advanced managed switch with 16 Gigabit LAN ports with PoE (120W) and 2 SFP ports. The CBS250-16P-2G features Layer 3 management, VLAN and QoS and protects your network with multiple security features. This model comes with an internal power supply.
TheCisco CBS250-16P-2G is a professional Layer 3 switch with powerful management features and robust network security. This model has 16 Gigabit Ethernet ports and 2 SFP uplink ports. With 36 Gbps throughput, it creates lightning fast connections to connected devices such as access points, computers and IP phones.
Cisco Business switches, routers, and wireless access points are managed using the Cisco Business dashboard. The interface and widgets can be easily configured for proactive network administration. In addition, Cisco Business 250 Series switches have a built-in probe to run the Cisco Business dashboard, eliminating the need to add special hardware or a virtual machine to the environment.
