Advanced features for demanding environments at an affordable price Your business is growing, and that means more customers, more opportunities, and more attention on your company. The only problem: Your network was built for a smaller operation. As you add more devices, applications, and users, your IT environment will become increasingly difficult and expensive to manage. Even worse, as the network becomes more complex and overloaded, your users are likely to see sluggish performance and even outages.
With customers and employees depending on your business more than ever before, a slow or unreliable network is not an option. You need an IT backbone that provides excellent performance, nonstop availability, and advanced security. The ideal network will be easy to manage, support advanced features that will grow with your company, and be at a price thats affordable. Cisco 550X Series Stackable Managed Switches The Cisco® 550X Series (Figure 1) are the next-generation stackable managed Ethernet switches that provide the advanced capabilities and superior performance you need to support a more demanding network environment at an affordable price.These switches incorporate fan and power hardware redundancy, increasing overall network availability. The SG550X and SF550X models provide 24 or 48 ports of Gigabit Ethernet and Fast Ethernet connectivity with 10 Gigabit uplinks. The SX550X models provide 12, 16, 24, or 48 ports of 10 Gigabit Ethernet with both copper and fiber connection options, providing a solid foundation for your current business applications, as well as those you are planning for the future. At the same time, these switches are easy to deploy and manage, without a large IT staff. Features and benefits Cisco 550X Series switches provide the advanced feature set that growing businesses require and that high-bandwidth applications and technologies demand. These switches can improve the availability of your critical applications, protect your business information, and optimize your network bandwidth to more effectively deliver information and support applications. The switches provide the following benefits. High-performance 10 Gigabit Ethernet Cisco 550X 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 the SX550X switches, you can easily and cost-effectively enable 10G connections to servers and network storage devices with standard RJ-45 Ethernet cable. You can also connect your SG550X access switches to the SX550X aggregation with 10G SFP+ fiber, building a high-performance backbone to speed up the overall operation of your network.
High reliability and resiliency In a growing business in which availability 24 hours a day, 7 days a week is critical, you need to assure that employees and customers can always access the data and resources whenever 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 550X 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 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 and continue operating even after a failure. The Cisco 550X 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. Power over Ethernet Plus (PoE+) and 60W PoE Cisco 550X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802.3at), providing up to 30 watts per port.
The switches also support 60W PoE on selected ports to power compact switches, high-power wireless access points, or connected lighting. The power is managed in a smart fashion such that only the amount of power the endpoint needs 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. 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 550X Series switches are also fully backward compatible with IEEE 802.11af PoE and Cisco legacy PoE protocols.Hardware Specifications : - 357.12 mpps Switching capacity - 480 Gbps Switching capacity - 20x 10 GE SFP+ - 4x 10 GE copper/SFP+ combo - 2 MB Packet buffer.

Dynamic VLAN assignment using RADIUS server along with 802.1x client authentication. Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS.
Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices. Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR). In VLAN One-to-One Mapping, on an edge interface C-VLANs are mapped to S-VLANs and the original C-VLAN tags are replaced by the specified S-VLAN.VLANs transparently cross over a service provider network while isolating traffic among customers. Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and p. Rovides, per edge interface, multiple mappings of different C-VLANs to separate S- VLANs. Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain. UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networks.

To act as a supplicant to another switch.
Enables extended secure access in areas outside the wiring closet (such as conference rooms). A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops.
This prevents edge devices not in the network administrators control from becoming Spanning Tree Protocol root nodes. Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP server.
When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing.The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DoS attacks in the network, thereby increasing network availability. Makes sure that the switch will receive and process management and protocol traffic no matter how much traffic is received. A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user-configured access level and the access method of the user.
