• High-performance 10 Gigabit Ethernet
  Cisco 350X Series switches break the barrier of 10 Gigabit Ethernet adoption by providing affordable and flexible configurations customized for the demanding network requirements of small and medium businesses. With 10G copper ports on SG350XG switches, you can easily and cost-effectively enable 10G connections to servers and network storage devices with standard RJ45 Ethernet cable. You can also connect your SG350X access switches to the SG350XG aggregation with 10G SFP+ fiber connections, building a high-performance backbone to speed up the overall operation of your network.
• Easy deployment and use
  Cisco 350X Series switches are designed to be easy to use and manage by commercial customers or the partners that serve them.
• Power over Ethernet Plus (PoE+) and 60W PoE
  PoE capabilities simplify the deployment of advanced technologies by allowing you to connect and power network endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 350X Series switches are also fully backward compatible with IEEE 802.11af PoE and Cisco legacy PoE protocols. Cisco 350X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802. at), providing up to 30 watts per port. The switches also support 60W PoE on select ports to power compact switches, high-power wireless access points, or connected lighting. The PoE power is intelligently managed in a way such that only the amount of power needed by endpoints is delivered to it and not wasted. As a result, the switches can support devices that require more power, such as 802.11ac wireless access points, video-based IP phones, surveillance cameras, and more.
• High reliability and resiliency
  In a growing business where availability 24 hours a day, 7 days a week is critical, you need to assure that employees can always access the data and resources they need. In these environments, stackable switches can play an important role in eliminating downtime and improving network resiliency. For example, if a switch within a Cisco 350X Series stack fails, another switch immediately takes over, keeping your network up and running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity. The Cisco 350X Series also supports dual images, allowing you to perform software upgrades without having to take the network offline or worry about the network going down during the upgrade.
• True stacking
  Some switches claim to support stacking but in practice support only "clustering," meaning that each switch must still be managed and configured individually. Cisco 350X Series switches provide true stacking capability, allowing you to configure, manage, and troubleshoot all switches in a stack as a single unit, with a single IP address, for up to 4 units and a maximum of 208 Ethernet ports. A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the stack members. This capability can radically reduce complexity in a growing network environment while improving the resiliency and availability of network applications. True stacking also provides other cost savings and administrative benefits through features such as cross-stack QoS, VLANs, LAGs, and port mirroring, which clustered switches can't support.
• Strong security
  Cisco 350X Series switches provide the advanced security features you need to protect your business data and keep unauthorized users off the network.
• Networkwide Automatic Voice Deployment
  Using a combination of Cisco Discovery Protocol, 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 VLAN and 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 350X Series can support the transition to the next generation of networking and operating systems. 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 350X Series switches have successfully completed rigorous IPv6 testing and have received the USGv6 and IPv6 Gold certification.
• Advanced Layer 3 traffic management
  The Cisco 350X Series enables a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. 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. You can minimize the need to manually configure routing devices and simplify the ongoing operation of the network.

The Cisco 350X Series Stackable Managed Switches are a line of stackable managed Ethernet switches that provide the rich capabilities you need to support a more demanding network environment at a very affordable price. The SG350X models provide Gigabit Ethernet connectivity with 10 Gigabit uplinks. In addition, these switches are easy to deploy and manage without a large IT staff. The SG350X platforms are Cisco's cost-effective platforms with 10 Gigabit Ethernet and stacking.
Cisco 350X Series switches are designed to protect your technology investment as your business grows. Unlike switches that claim to be stackable but have elements that are administered and troubleshot separately, the Cisco 350X Series provides true stacking capability, allowing you to configure, manage, and troubleshoot multiple physical switches as a single device and more easily expand your network.
A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the stack members. Overall, the Cisco 350X Series provides the ideal technology foundation for a growing business.
