It is part of Cisco's 500 Series of stackable switches, which are designed to provide a scalable and flexible network infrastructure for growing organizations. The SG500-28P has 24 Gigabit Ethernet ports and 4 Gigabit Ethernet combo ports (with SFP and RJ-45 connectors) for connecting to other devices such as servers, workstations, and other switches. It also supports Power over Ethernet (PoE) on all of its ports, which allows it to power devices such as IP phones and wireless access points. The switch supports advanced features such as Quality of Service (QoS), security, and network virtualization. It can also be managed and configured through a web-based interface or the Cisco Smartport Macro, which provides pre-configured templates for different types of network devices. The SG500-28P-K9-NA model specifically has Layer 3 advanced feature set, including routing protocols and other advanced functionalities, while Layer 2 switch has less functionality comparing to Layer 3. Performance and Reliability The Cisco SG500-28P-K9-NA is a high-performance and reliable Ethernet switch that is designed for small and medium-sized businesses. In terms of performance, the switch has a non-blocking switching fabric, which means that it can handle the full-wire speed on all ports simultaneously without any loss of performance. The switch also supports Quality of Service (QoS) and bandwidth control, allowing you to prioritize certain types of traffic and ensure that critical applications have the bandwidth they need. In terms of reliability, the switch has several features to ensure that it stays up and running. It has a redundant power supply, which means that if the primary power supply fails, a secondary one will take over without any interruption in service. The switch also has advanced security features, such as 802.1X authentication and access control lists, to protect against unauthorized access and network attacks. Additionally, the switch supports Cisco's Discovery Protocol and Link Layer Discovery Protocol (LLDP) which allows you to automatically discover and map your network, providing easier troubleshooting and management. Interface Provided for Digital Workplace The Cisco SG500-28P-K9-NA is a 28-port managed Ethernet switch from the Cisco Small Business SG500 series. It is designed for small businesses that are looking for a reliable and easy-to-use switch to power their digital workplace. The switch provides 28 Gigabit Ethernet ports (24 of which are PoE-enabled) which can be used to connect devices such as computers, servers, and IP phones. Additionally, the switch supports Power over Ethernet (PoE) which allows the devices connected to it to receive power via the Ethernet cable, eliminating the need for an additional power source. The model also supports advanced features such as Quality of Service (QoS) which allows for prioritization of different types of traffic, and access control lists (ACLs) which can be used to secure the network. The switch has a web-based management interface that allows for easy configuration and monitoring of the switch. It also offers many security features like IPv6, SSH/SSL, ACLs, and VLANs which can provide added layer of security to your network infrastructure. In summary the model is designed to provide a cost-effective, high-performance and feature-rich network solution for small businesses, which offer many advance features like PoE,QoS,ACLs, and Security features to help in building secure, reliable and high-performance networks.
