The Cisco Small Business SG500X-48 (SG500X-48-K9-NA) is a stackable managed switch that provides 48 Gigabit Ethernet ports and 4 10-Gigabit Ethernet ports. It offers advanced security and network management features, such as Quality of Service (QoS), VLANs, and access control lists (ACLs). The switch also supports stacking, which allows multiple units to be connected and managed as a single device, providing increased scalability and flexibility for growing networks. Additionally, it can support PoE and PoE+. This switch is ideal for small and medium-sized businesses that require a high-performance and secure network infrastructure.

The Cisco Small Business SG500X-48 48-Ports Gig + 4-Ports 10-Gig Stackable Managed Switch (SG500X-48-K9-NA) is designed to provide resiliency and high availability for network environments.

Resiliency refers to the ability of a system to continue functioning in the event of a failure or disruption. The SG500X-48-K9-NA has several features that contribute to its resiliency, including:

• StackPower: This feature allows multiple switches to be connected and powered together, providing a redundant power source in case of a power failure.
• StackWise: This feature allows multiple switches to be connected and managed as a single unit, providing a single point of management and ensuring that traffic is automatically rerouted in case of a switch failure.
• Loop Protection: This feature detects and prevents loops in the network, which can cause network outages and slowdowns.

High availability refers to the ability of a system to remain operational with minimal downtime. The SG500X-48-K9-NA has several features that contribute to its high availability, including:

• Redundant Power Supply: The switch has two power supply slots, allowing for a redundant power source in case of a power supply failure.
• Hot Swappable Power Supplies: The power supplies can be replaced without disrupting the operation of the switch.
• Link Aggregation Control Protocol (LACP): This protocol allows multiple physical connections to be combined into a single logical link, providing redundancy in case of a link failure.
• Rapid Spanning Tree Protocol (RSTP): This protocol ensures that the network topology is reconfigured quickly in case of a link failure, minimizing downtime.

The Cisco Small Business SG500X-48 48-Ports Gig + 4-Ports 10-Gig Stackable Managed Switch (SG500X-48-K9-NA) is known for its high reliability and performance. It is a stackable-managed switch that offers advanced features such as Quality of Service (QoS), VLAN, and security features that are typically found in enterprise-level switches.

The switch supports 48 Gigabit Ethernet ports and 4 10 Gigabit Ethernet ports, which provide a high-speed, reliable network for businesses of all sizes. Additionally, the switch supports stackable configurations, which allows for easy expansion and management of the network.

The switch also offers advanced security features such as access control lists, port security, and IP-MAC-Port-VID (IMPV) binding, which help to protect the network from unauthorized access and malicious attacks.
