Cisco SG350-52P-K9 52 Ports Manageable Switch 1GBPS PoE+ Refurbished

The Cisco SG350-52P-K9 belongs to the Small Business Series, emphasizing its suitability for smaller enterprises. This switch is equipped with 52 ports, providing a substantial number of connections for devices and facilitating the efficient flow of data within the network. This switch, with its 52 ports, SFP compatibility, Power over Ethernet Plus (PoE+), and Layer 3 capabilities, caters to the needs of small businesses seeking robust network management.

A standout feature of the Cisco SG350-52P-K9 is its Power over Ethernet Plus-PoE+ capability. This technology enables the switch to deliver power to connected devices such as IP cameras, VoIP phones, and wireless access points through the same Ethernet cables used for data transmission. This not only simplifies cable management but also eliminates the need for separate power sources, contributing to a more organized and streamlined network setup.

The Layer 3 capabilities of the Cisco SG350-52P-K9 elevate its performance by allowing for routing at the network layer. This means that the switch can make intelligent decisions based on IP addresses, enhancing network efficiency and facilitating communication between different subnets. Layer 3 switches are particularly valuable in scenarios where advanced routing features are required for optimal network functioning.

Designed with practicality in mind, the Cisco SG350-52P-K9 features a rack-mountable design. This allows for easy integration into standard server racks, optimizing space utilization in data centers and server rooms. The rack-mountable form factor ensures a tidy and organized network setup, contributing to overall system reliability and ease of maintenance.

The manageability of the Cisco SG350-52P-K9 is a crucial aspect that aligns with the demands of modern network administration. With Gigabit Ethernet manageability, administrators can efficiently monitor and control the switch, ensuring that it operates in accordance with the organization's network policies. This level of manageability is essential for maintaining a secure and well-organized network infrastructure.

Small businesses often undergo growth and expansion, and the Cisco SG350-52P-K9 is well-positioned to accommodate these changes. The switch's scalability allows businesses to add more devices to their network without the need for a complete overhaul. This adaptability is a key factor for businesses that anticipate future growth and want a network infrastructure that can scale alongside their evolving needs.

Security is paramount in any network, and the Cisco SG350-52P-K9 addresses this concern with a range of security features. These may include but are not limited to Access Control Lists (ACLs), which permit or deny traffic based on specified criteria, and secure management protocols. The implementation of these security measures helps safeguard the network against unauthorized access and potential threats.

Network reliability is a non-negotiable requirement for businesses, and the Cisco SG350-52P-K9 addresses this need through features that enhance reliability and provide redundancy. These may include link aggregation to ensure a continuous connection even if one link fails, as well as Spanning Tree Protocol (STP) for loop prevention. The incorporation of these features minimizes the risk of network downtime due to hardware failures or configuration errors.

The SG350-52P-K9 Cisco Small Business 52 Ports Manageable Switch is a high-performance network switch that is designed for small to medium-sized businesses. The switch offers 52 ports of Gigabit Ethernet connectivity and advanced features that enable users to easily manage and secure their networks.

One of the key features of this product is its ability to provide high-speed data transfer rates of up to 1 Gbps. This allows for faster file transfers and improved network performance, making it ideal for businesses that rely on high-speed data transfer for their operations.

Another great feature of the model is its advanced security capabilities. The switch supports various security protocols, including 802.1X, port security, and access control lists, which help protect the network from unauthorized access. Additionally, the switch also includes advanced Quality of Service (QoS) features that allow users to prioritize different types of traffic, such as voice and video, to ensure that they receive the bandwidth they need.

The part also comes with a user-friendly web-based interface that makes it easy to configure and manage the switch. Users can access the interface from any device with a web browser, which makes it convenient to manage the switch remotely.

The SG350-52P-K9 Cisco Small Business 52 Ports Manageable Switch has multiple interfaces that allow administrators to monitor and manage the network. These interfaces include:

• Web Interface: This is the main interface used to access and configure the switch. It can be accessed via a web browser and requires a username and password to log in. The web interface allows administrators to configure VLANs, port security, QoS, and other features of the switch.
• Command Line Interface (CLI): This interface allows administrators to access the switch via a command-line interface (CLI) using a serial console or Telnet/SSH client. The CLI provides a more advanced level of control and configuration options for the switch.
• SNMP: Simple Network Management Protocol (SNMP) allows the switch to be managed and monitored remotely using SNMP management software. This allows administrators to view switch statistics, alarms, and other information from a central location.
• Syslog: The Syslog feature allows the switch to send log messages to a remote syslog server, providing administrators with detailed information about switch activity and any errors or issues that may occur.
• LLDP/CDP: Link Layer Discovery Protocol (LLDP) and Cisco Discovery Protocol (CDP) allow the switch to discover and display information about other network devices connected to it, making it easier for administrators to identify, and network issues.

The Cisco SG350-52P-K9 52 Ports Manageable Switch is designed with resiliency and high availability in mind.

Resiliency refers to the ability of a system to continue functioning in the face of unexpected events or failures. This switch has several features that enhance its resiliency, such as:

• Redundant power supplies: The switch has two power supplies that can work together to provide continued power in case one of them fails.
• Link Aggregation Control Protocol (LACP): LACP allows multiple links to be bundled together to form a single logical link. This means that if one link goes down, the others can take over to maintain connectivity.
• Rapid Spanning Tree Protocol (RSTP): RSTP helps to prevent loops in the network by quickly blocking redundant paths. This helps to ensure that there is always a functioning path for data to travel on.

High availability refers to the ability of a system to remain operational and accessible at all times. This switch has several features that enhance its high availability, such as:

• Hot-swappable power supplies: The power supplies can be easily replaced without disrupting the operation of the switch.
• SNMP v3 support: SNMP v3 allows for secure, remote management of the switch, which means that it can be managed and monitored from anywhere.
• Quality of Service (QoS) support: QoS allows for the prioritization of different types of traffic, ensuring that important data is delivered quickly and reliably.
