SG220-50P-K9-NA Cisco 220 Series 50 Ports Ethernet Switch Refurbished

The Cisco SG220-50P-K9-NA Small Business Smart Plus switch is a networking device that helps connect multiple devices within a network. It's designed specifically for small businesses, providing essential features to manage network traffic efficiently.

This switch comes with 4 Power over Ethernet Plus (PoE+) Ethernet ports. These ports can supply both power and data to compatible devices, like IP phones, wireless access points, or security cameras, reducing the need for additional power adapters.

With a total of 44 PoE Ethernet ports, this switch allows for the connection of various PoE-enabled devices without requiring separate power sources. These ports are suitable for devices needing power and data connectivity, simplifying setup and management.

Additionally, it features 2 Combo Gigabit Small Form-factor Pluggable (SFP) ports. These ports support both Gigabit Ethernet connections and SFP modules, enabling flexible connectivity for different networking needs.

The Cisco SG220-50P-K9-NA switch offers versatility in deployment. It can be used as a desktop switch, suitable for smaller setups where space is limited, or mounted in a rack for larger network configurations, providing scalability and organization.

This switch operates at Layer 2 of the OSI (Open Systems Interconnection) model, enabling it to manage traffic based on MAC (Media Access Control) addresses. It offers functionalities like VLANs (Virtual Local Area Networks), QoS (Quality of Service), and link aggregation for efficient network administration.

The inclusion of PoE+ and PoE Ethernet ports streamlines the setup process, allowing devices to connect directly to the switch without the need for separate power sources.

The Combo Gigabit SFP ports offer flexibility by supporting various networking interfaces, allowing for the integration of different types of devices into the network infrastructure.

Being a Layer 2 managed switch, it provides a range of management features that assist in optimizing network traffic, enhancing security, and ensuring smoother operation of the network.

The Cisco SG220-50P-K9-NA is a 50-port Ethernet switch from the Cisco 220 Series. It is a high-performance switch that is designed for small and medium-sized businesses, as well as for branch offices. It is a layer 2 switch which means it can only handle data link layer functionality, it can not handle Network layer functionality like routing.

It offers advanced features such as Quality of Service (QoS) to prioritize traffic, VLANs to segment network traffic, and security features to protect against network threats. It also has energy-efficient technology that helps to reduce power consumption, and a compact design, making it easy to deploy and manage. Additionally, it supports Power over Ethernet (PoE) which allows devices to receive power through the Ethernet cable, eliminating the need for an external power supply.

The Cisco SG220-50P-K9-NA is a 50-port Ethernet switch from the Cisco 220 Series. It offers a variety of benefits and features that make it well-suited for small and medium-sized businesses, as well as for branch offices.

Some of the key features of this switch include:

• 50 Gigabit Ethernet ports with Auto-MDI/MDI-X, for easy and flexible connectivity.
• IEEE 802.3af and 802.3at Power over Ethernet (PoE) support, providing up to 30 watts per port.
• Advanced Quality of Service (QoS) to prioritize traffic and ensure that critical applications receive the bandwidth they need.
• VLANs to segment network traffic and improve security.
• Security features to protect against network threats, including support for IEEE 802.1X port-based and MAC-based access control.

The Cisco SG220-50P-K9-NA is a 50-port Ethernet switch from the Cisco 220 Series. It is designed to provide resiliency and high availability, which are important features that help to ensure that your network stays up and running even in the event of a failure or other disruption.

One way in which the switch provides resiliency is through its support for Link Aggregation Control Protocol (LACP), which allows you to bundle multiple physical ports together to create a single logical link. This helps to ensure that if one of the physical ports fails, traffic can still be sent and received over the other ports in the bundle.

Another way in which the switch provides resiliency is through its support for Rapid Spanning Tree Protocol (RSTP), which helps to prevent loops in the network and ensure that there is always a single active path between two devices. This helps to ensure that if one link in the network fails, traffic can still be sent and received over another link.

The switch also supports Hot Standby Router Protocol (HSRP) allows multiple routers to work together to present the appearance of a single virtual router to hosts on a LAN, which allows the network to continue forwarding packets even if one of the routers fails.

Additionally, the switch also supports other features such as loop guard, BPDU guard, and root guard which are designed to prevent loops and improve the overall stability of the network.
