Features

High-Performance 10 Gigabit Ethernet

The Cisco SG550XG-24T Ghana switch breaks the barrier of 10 Gigabit Ethernet adoption by providing affordable and flexible configurations customized for the demanding network requirements of small and medium businesses. Connect your Cisco SG550XG-24T Ghana access switch to the SG550XG aggregation with 10G SFP+ fiber, building a high-performance backbone to speed up the overall operation of your network.

High Reliability and Resiliency

The Cisco SG550XG-24T Ghana 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 SG550XG-24T Ghana 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 SG550XG-24T Ghana 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 SG550XG-24T Ghana switch supports 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.

Power Efficiency

The Cisco SG550XG-24T Ghana switch integrates a variety of power-saving features across all models, providing the industry’s most extensive energy-efficient switching portfolio. This switch is designed to conserve energy by optimizing power use, which helps protects the environment and reduce your energy costs. They provide an eco-friendly network solution without compromising performance. Cisco 550X Series switches feature:

• Support for the Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods
• The latest application-specific integrated circuits (ASICs), which use low-power 28- or 40-nanometer technology and low-power, high-performance ARM CPUs
• Automatic power shutoff on ports when a link is down
• LEDs that can be turned off to save power
• Embedded intelligence to adjust signal strength based on the length of the connecting cable
• Smart fans in which fan speed is automatically adjusted according to switch temperature to decrease acoustic noise and save power

Advanced Stacking

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 operates as a single entity constituting all the ports of the stack members. The Cisco SG550XG-24T Ghana stacking 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 cannot support. Using standard 10G fiber or copper connections, Cisco SG550XG-24T Ghana supports both local and horizontal stacking deployments and 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.

Strong Security

Cisco SG550XG-24T Ghana provides the advanced security features you need to protect your business data and keep unauthorized users off the network:

• Embedded Secure Sockets Layer (SSL) encryption protects management data traveling to and from the switch.
• Extensive access control lists (ACLs) restrict sensitive portions of the network to keep out unauthorized users and guard against network attacks.
• Guest VLANs let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic.
• Support for advanced network security applications such as IEEE 802.1X port security tightly limits access to specific segments of your network. Web-based authentication provides a consistent interface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE 802.1X clients on each endpoint.
• Advanced defense mechanisms, including dynamic Address Resolution Protocol (ARP) inspection, IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate network attacks. Combinations of these protocols are also referred to as IP-MAC port binding (IPMB).
• IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard, and neighbor binding integrity check, providing unparalleled protection against a vast range of address spoofing and man-in-the-middle attacks on IPv6 networks.
• Time-based ACLs and port operation restrict access to the network during predesignated times, such as business hours.
• Uniform MAC address-based security can be applied automatically to mobile users as they roam between wireless access points.
• Secure Core Technology (SCT) helps ensure that the switch is able to process management traffic in the face of a denial-of-service (DoS) attack.
• Private VLAN provides Layer 2 isolation between devices on the same VLAN.
• Storm control can be applied to broadcast, multicast, and unknown unicast traffic.
• Protection of management sessions is possible using RADIUS, TACACS+, and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.
• DoS attack prevention maximizes network uptime in the presence of an attack.

Advanced Layer 3 Traffic Management

The Cisco SG550XG-24T Ghana enables 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 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. Additionally, Cisco SG550XG-24T Ghana provides dynamic Layer 3 routing features. With these capabilities, you can minimize the need to manually configure routing devices and simplify the ongoing operation of the network.

IPv6 Support

As the IP address scheme evolves to accommodate a growing number of network devices Cisco SG550XG-24T Ghana can support the transition to the next generation of networking and operating systems. Cisco SG550XG-24T Ghana 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 SG550XG-24T Ghana has successfully completed rigorous IPv6 testing and have received the USGv6 and IPv6 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 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.
