Cisco 48-port 10/100 PoE Stackable Switch
Cisco 550X Series Stackable Managed Switches
Cisco 550X Series switches are designed to protect your technology investment as your business grows. Unlike
Features and Benefits
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 SG550XG 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 SG550X access switches 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 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 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.
- 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
Easy Deployment and Use
- Simple and advanced mode graphic user interfaces reduce the time required to deploy, troubleshoot, and manage the network and allow you to support sophisticated capabilities without increasing IT head count.
- Configuration wizards simplify the most common configuration tasks and provide the ultimate tool for anyone to easily set up and manage the network. The switches also support Textview, a full command-line interface (CLI) option for customers or partners that prefer it.
- The USB port on the switch enables easy image and configuration transfer for faster deployment or upgrade. Using Auto Smart ports intelligence, the switch can detect a network device connected to any port and automatically configure the optimal security, quality of service (QoS), and availability on that port.
- Cisco Discovery Protocol discovers Cisco devices and allows devices to share critical configuration information, simplifying network setup and integration.
- Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your switches and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations.
- The Cisco FindIT utility, which works through a simple toolbar on the user’s web browser, discovers Cisco devices in the network and displays basic information, such as serial numbers and IP addresses, to aid in configuration and deployment.

Simplified IT Operation
- True stacking allows you to configure, manage, and troubleshoot multiple physical switches as a singleentity.
- Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches within aseries support the same feature set, making it easier to manage and support all switches across 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.
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 550X series provide 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.
As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 550X Series
