The Cisco SG500-28P-K9-NA is a high-performance, reliable Ethernet switch that can support a wide range of applications for small and medium-sized businesses.
In terms of performance, it supports both Fast Ethernet and Gigabit Ethernet speeds, allowing for high-speed data transfer. The switch also has a non-blocking architecture, which means that all of its ports can operate at their full bandwidth simultaneously, without any loss of performance.
The switch also supports advanced Quality of Service (QoS) features, which allow you to prioritize different types of network traffic, such as voice or video, to ensure that they are delivered with the appropriate level of service.
In terms of reliability, the model has several features that help to ensure the availability of your network. It supports Cisco StackWise technology, which allows you to stack multiple switches together for increased resiliency and ease of management. It also supports Redundant Power Supply (RPS) options for increased power availability and failover protection. Additionally, it has advanced security features, such as 802.1X authentication and access control lists, to help protect your network against unauthorized access and other security threats.
Interface Provided for Digital Workplace
The Cisco SG500-28P is a 28-port Ethernet switch designed for use in small and medium-sized businesses.

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).
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.
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 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 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.
