Power and Innovation

The Cisco Small Business SG500X-48 48-Ports Gig + 4-Ports 10-Gig Stackable Managed Switch (SG500X-48-K9-NA) is a powerful and innovative networking solution designed for small and medium-sized businesses. With its 48 Gigabit Ethernet ports and 4 10-Gigabit Ethernet ports, this switch can handle high-bandwidth applications and provide fast and reliable connectivity for all of your network devices.

One of the key features of the SG500X-48-K9-NA is its ability to stack multiple switches together. This allows for a more efficient use of space and makes it easy to expand your network as your business grows. The stackable design also allows for easy management and monitoring of all connected switches from a single point of access.

In terms of security, the product offers advanced features such as advanced access control lists (ACLs), secure shell (SSH) protocol, and secure socket layer (SSL) protocol. These features ensure that your network is protected from unauthorized access and that data is transmitted securely.

Another innovative feature of the model is its ability to support Power over Ethernet (PoE) on all 48 Gigabit Ethernet ports. This allows you to power network devices such as IP phones and wireless access points directly from the switch, eliminating the need for additional power supplies.

Resiliency and High Availability

The Cisco Small Business SG500X-48 48-Ports Gig + 4-Ports 10-Gig Stackable Managed Switch (SG500X-48-K9-NA) is designed with resiliency and high availability features to ensure the smooth operation of a network.

Resiliency refers to the ability of the switch to continue functioning even in the event of a failure or malfunction. The product has several resiliency features that ensure network uptime, such as:

  • StackWise Plus: This technology allows multiple switches to be stacked together and function as a single entity, providing redundancy and failover capabilities.
  • FlexStack Plus: This feature allows for the stacking of switches over longer distances, providing redundancy and failover capabilities.
  • Link Aggregation Control Protocol (LACP): This protocol allows for the grouping of multiple physical links together to form a single logical link, providing redundancy and failover capabilities.

High availability refers to the ability of the switch to continue functioning without interruption. The part has several high availability features that ensure network uptime, such as:

  • Hot Standby Router Protocol (HSRP): This protocol allows for the configuration of a primary and secondary switch, providing redundancy and failover capabilities.
  • Virtual Router Redundancy Protocol (VRRP): This protocol allows for the configuration of a primary and secondary switch, providing redundancy and failover capabilities.
  • Rapid Spanning Tree Protocol (RSTP): This protocol allows for the rapid recovery of a failed link, providing redundancy and failover capabilities.

High Reliability

The Cisco Small Business SG500X-48 48-Ports Gig + 4-Ports 10-Gig Stackable Managed Switch (SG500X-48-K9-NA) is a highly reliable and robust network switch. It is designed for small to medium-sized businesses and offers advanced features such as:

  • Stackable design: The switch can be stacked up to 8 units, providing a scalable and flexible network solution.
  • Advanced security: The switch offers advanced security features such as access control lists (ACLs), IP telephony support, and Quality of Service (QoS) to ensure that the network is secure and reliable.
  • High availability: The switch supports redundant power supplies, hot-swappable modules, and stacking capabilities to ensure that the network is always available.
  • Easy management: The switch offers a web-based interface and Cisco Smartports for easy configuration and management of the network.
  • Comprehensive warranty: The switch comes with a limited lifetime warranty, providing peace of mind and protection against defects or hardware failures.

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 configurations 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 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.
