Advanced Network Management and Security

The SF550X-24-K9-NA Cisco Small Business 24 Ports Layer 3 Managed Switch offers advanced network management and security capabilities to ensure the safety and performance of your network. Some of these features include:

  • VLAN (Virtual LAN) Support: This feature allows you to segment your network into multiple virtual networks, providing greater security and traffic management capabilities.
  • Quality of Service (QoS): This feature prioritizes different types of network traffic, ensuring that critical applications and services receive the bandwidth they need.
  • Access Control Lists (ACLs): This feature allows you to restrict access to specific network resources based on user or device characteristics.
  • Layer 3 Routing: This feature enables the switch to route traffic between different VLANs, allowing for a more efficient use of network resources and improved performance.
  • DHCP (Dynamic Host Configuration Protocol) Server: This feature allows the switch to assign IP addresses to connected devices, simplifying network management.
  • SNMP (Simple Network Management Protocol) Support: This feature allows you to monitor and manage the switch remotely, making it easier to troubleshoot and maintain your network.
  • IPv6 Support: This feature allows the switch to support the latest version of the Internet Protocol, providing greater security and performance.

Power-over-Ethernet (PoE) and Energy Efficiency

The SF550X-24-K9-NA Cisco Small Business 24 Ports Layer 3 Managed Switch is designed with both Power-over-Ethernet (PoE) and energy efficiency in mind.

Power-over-Ethernet (PoE) is a feature that allows the switch to provide power to connected devices through the Ethernet cables. This eliminates the need for separate power adapters and can be a cost-effective solution for powering devices such as IP phones, wireless access points, and surveillance cameras. The SF550X-24-K9-NA supports PoE+ and can provide up to 30W of power per port, allowing for flexible deployment of PoE-enabled devices.

In addition to PoE, the SF550X-24-K9-NA also includes energy-saving features to reduce power consumption. The switch supports Energy Efficient Ethernet (EEE) which reduces power consumption during periods of low network activity by putting the ports into a low-power idle state. The switch also has a built-in power supply that is designed to be highly efficient, further reducing power consumption. Additionally, the switch can be configured to automatically enter a low-power mode when not in use, reducing power consumption.

Easy Installation and Configuration

The SF550X-24-K9-NA Cisco Small Business 24 Ports Layer 3 Managed Switch is designed to be easy to install and configure, making it an ideal option for small businesses looking to upgrade their network infrastructure. Some of the key features that support easy installation and configuration include:

  • Plug-and-play design: The switch is designed to be easy to set up, with minimal configuration required out of the box. Simply connect the switch to your network and power it on, and it will automatically configure itself.
  • Web-based management interface: The switch comes with a web-based management interface that allows for easy configuration and monitoring of the switch. This interface is intuitive and user-friendly, making it easy for even non-technical users to navigate.
  • Auto-configuration: The switch can automatically configure itself based on the network it is connected to, eliminating the need for manual configuration.
  • VLAN support: The switch supports VLANs, allowing for easy segmentation of the network for improved security and performance.
  • Layer 3 functionality: The switch is a Layer 3 managed switch, which means that it can handle more advanced routing and switching functionality than a basic Layer 2 switch.
  • Auto-detection and auto-configuration of devices.
  • Support for Cisco Small Business Quick Start and Cisco Small Business Pro services.
  • Advanced security features like DHCP Snooping, IP Source Guard, and Storm Control.
  • Easy firmware upgrade.
  • Support for Cisco Smart Software Manager On-Prem.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
