Cisco 550X Series Switches - physical stacking of switches

Unlike stackable switches that have components that are administered and diagnosed separately, the Cisco 550X Series provides real, end-to-end stacking of switches, allowing you to configure, manage and troubleshoot multiple switches as if they were one device, making network expansion much easier.

Why Cisco? Features and benefits of the 550X series switches

High performance 10 Gigabit Ethernet ports
The Cisco 550X series switches have 10 Gigabit Ethernet ports, providing low-cost and flexible configurations to meet the high networking requirements of small and medium-sized enterprises. The 10G copper ports in the SX550X switches allow connections to servers and network storage devices using standard RJ-45 Ethernet cable..

Easy implementation and use
Cisco 550X series switches are designed for small and medium enterprises. They are extremely simple to use and manage.

550X Series Switches - key features

- Smart Network Application (SNA) is an innovative network level monitoring and management tool built into the series Cisco 250 to 550X switches. It provides the ability to display network topology and connection status, allows you to monitor events, implement configurations and update software in multiple switches on the network.

- FindIT Network Manager and Probe are designed to manage switches, routers and wireless access points from the Cisco 100 to 500 series. They not only react to events, but allow proactive network management. The Cisco 550X series switches support the built-in FindIT Network Probe, which eliminates the need to configure separate hardware or a virtual machine on site.

- The FindIT Network Discovery tool works with a simple toolbar in your web browser. It allows you to discover Cisco devices on the network and display basic device information, inventories or new firmware updates, helping you configure and speed up the deployment of Cisco Small Business products.

- The advanced but easy-to-use graphical user interfaces reduce the time needed for deployment, troubleshooting and network management, and allow for convenient use of advanced features.

- Configuration wizards simplify the most common configuration tasks and are a great tool for easy network configuration and management.

- The switches also support text interface Command-Line Interface (CLI).

- With Auto Smart ports, the switch detects a network device connected to any port and automatically configures optimal security, quality of service (QoS) and availability on that port.

- The Cisco DiscoveryProtocol detects Cisco devices and allows them to share key configuration information, simplifying network configuration and integration.

- The SNMP (Simple Network Management Protocol) protocol allows you to configure switches and other Cisco devices and manage them remotely, which improves IT department operations and facilitates mass configurations.

- The USB port in the switch provides easy transfer of images and configurations, shortening the implementation or upgrade time.

- Networkwide Automatic Voice Deployment - Using Cisco Discovery Protocol, LLDP-MED, Auto Smartports and Voice Services Discovery Protocol (VSDP - Cisco's unique protocol), Customers can dynamically deploy an end-to-end voice network.
