High-performance 10 Gigabit Ethernet Cisco 550XG models in 550X series switches break the barrier of 10 Gigabit Ethernet adoption by providing affordable & flexible configurations customized for the demanding network requirements of small & medium businesses. With 10G copper ports on those switches, you can easily & cost-effectively enable 10G connections to servers & network storage devices with standard RJ45 Ethernet cable. You can also connect the 10G SFP+ fiber ports to 10G uplinks of your access switches, building a high-performance aggregation or core to speed up the overall operation of your network. High reliability & resiliency In a growing business in which availability 24 hours a day, 7 days a week is critical, you need to assure that employees & customers can always access the data & resources whenever they need. In these environments, stackable switches can play an important role in eliminating downtime & improving network resiliency. For example, if a switch within a Cisco 550X series stack fails, another switch immediately takes over, keeping your network up & running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity. The Cisco 550X series is designed to deliver hardware redundancy at the lowest incremental cost. Power redundancy is delivered with the Cisco RPS2300 external RPS system. If power to the switch is lost (through loss of AC power or power supply failure), the switch will automatically, and instantaneously, obtain its power from the RPS. This switchover occurs so quickly that there is no loss in traffic or reboot of the device. A Cisco RPS2300 system can be connected to up to six 550X series switches to provide redundancy. Cooling fan redundancy is delivered through preinstalled N+1 configuration. A switch can fully support all its capabilities for the life of the product with only N fans. If one of the fans fails, the spare fan automatically takes over, without causing any downtime. The Cisco 550X series provides an additional layer of resiliency with support for the Virtual Router Redundancy Protocol (VRRP). VRRP lets you extend the same resiliency that stacking provides for individual switches to complete network domains. By running VRRP between two stacks, you can instantly cut over from one stack to another in the event of a problem & continue operating even after a failure. Advanced stacking Some switches claim to support stacking but in practice support only "clustering, meaning that each switch must still be managed & configured individually. A true stack delivers a unified data & control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operates 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 & availability of network applications. True stacking also provides other cost savings & administrative benefits through features such as cross-stack Qo S, VLANs, LAGs, and port mirroring, which clustered switches cannot support. Using standard 10G fiber or copper connections, the Cisco 550X series supports both local & horizontal stacking deployments & the flexibility of ring or chain topology. The switches also have the capability to use link aggregation port as the stacking port, providing even higher stacking bandwidth for demanding applications. Easy deployment & use Cisco 550X series switches are designed to be easy to use & manage by small & medium businesses, commercial customers, or the partners that serve them. Advanced Layer 3 traffic management The Cisco 550X series enables a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively & efficiently. For example, the switches provide static LAN Layer 3 routing, allowing you to segment your network into workgroups & 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 & allowing it to manage primarily external traffic & security. in addition, Cisco 550X models provide dynamic Layer 3 routing features. With these capabilities, you can minimize the need to manually configure routing devices & simplify the ongoing operation of the network. IPv 6 support As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 550X series can support the transition to the next generation of networking & operating systems such as Windows 7, Vista, and Linux. These switches continue to support previous-generation IPv 4, allowing you to evolve to the new IPv 6 standard at your own pace & helping ensure that your current network will continue to support your business applications in the future. Cisco 550X series switches have successfully completed rigorous IPv 6 testing & have received the USGv 6 & IPv 6 Gold certification. Networkwide automatic voice deployment Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smart ports, and Voice Services Discovery Protocol (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 & Qo S parameters & 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 & receive an immediate dial tone. The switch automatically configures the device with the right VLAN & Qo S parameters to prioritize voice traffic. Main Specifications
