Cisco Business CBS350-48P-4G 48 Port Gigabit PoE Managed Network Switch

The Cisco Business 350 Series Switches, part of the Cisco Business line of network solutions, is a portfolio of affordable managed switches that provides a critical building block for any small office network. Intuitive dashboard simplifies network setup, and advanced features accelerate digital transformation, while pervasive security protects business-critical transactions. The Cisco Business CBS350-48P-4G 48 Port Gigabit PoE Managed Network Switch provides the ideal combination of affordability and capabilities for small offices and helps you create a more efficient, better-connected workforce.

The Cisco Business 350 Series Switches is a family of fixed-configuration managed Ethernet switches. Models are available with 8 to 48 ports of Gigabit Ethernet connectivity and Gigabit or 10-Gigabit uplinks, providing optimal flexibility to create exactly the right building block for small office networks. However, unlike other small business switching solutions that provide managed network capabilities only in the costliest models, all Cisco Business 350 Series Switches support the advanced security management capabilities and network features you need to support enterprise-class data, voice, security, and wireless technologies. At the same time, these switches are simple to deploy and configure, allowing you to take advantage of the managed network services your business needs.

Cisco Business 350 Series Switches are available with up to 48 Power over Ethernet (PoE) ports. This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly and at a lower cost. Models support 802.3af PoE and 802.3at PoE+.

Product Features

Networkwide Automatic Voice Deployment

Using a combination of Cisco Discovery Protocol, Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED), Auto Smartports, and Voice Services Discovery Protocol (or VSDP, a unique Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge around a single voice Virtual Local Area Network (VLAN) and Quality of Service (QoS) parameters and then propagate them out to the phones on the ports, where they are discovered. For example, automated 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

As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco Business 350 Series Switches can support the transition to the next generation of networking. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6 standard at your own pace and helping ensure that your current network will continue to support your business applications in the future. Cisco Business 350 Series Switches have completed rigorous IPv6 testing and have received the USGv6 and IPv6 Gold certification.

Advanced Layer 3 Traffic Management

The Cisco Business 350 Series Switches enable a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. For example, the switches provide static LAN Layer 3 routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading application performance.

With these capabilities, you can boost the efficiency of your network by offloading internal traffic-handling tasks from your router and allowing it to manage primarily external traffic and security.

Compact Design

The sleek and compact design for the Cisco Business 350 Series Switches provides additional deployment flexibility, including outside wiring closet installation such as in retail stores, open plan offices, and classrooms without disturbing the environment.
