SG350-52MP-K9-NA Cisco Rack-Mountable Switch Layer3 Refurbished

The Cisco SG350-52MP-K9-NA is a switch in the Cisco SG350 series of managed Ethernet switches. It has 52 ports, of which 50 are SFP (small form-factor pluggable) ports and 2 are Gigabit Ethernet ports. It is a Layer 3 switch, which means it can perform tasks such as routing and network segmentation in addition to switching. Additionally, this switch has PoE+ (Power over Ethernet Plus) capabilities, allowing it to provide power to connected devices over the Ethernet cables. The Cisco SG350-52MP-K9-NA belongs to the Small Business series, emphasizing ease of use, affordability, and scalability. With 52 ports, it provides ample connectivity for various devices in a network. The inclusion of Small Form-Factor Pluggable (SFP) ports enhances flexibility, allowing for different types of connections.

One standout feature of the Cisco SG350-52MP-K9-NA is its Power over Ethernet (PoE+) capability. PoE technology enables the switch to deliver power along with data through Ethernet cables, eliminating the need for separate power sources for connected devices such as IP cameras, VoIP phones, and wireless access points. This capability simplifies and reduces cable clutter.

• Cost-Efficiency: PoE+ eliminates the need for additional electrical outlets near each device, reducing costs.
• Flexibility: Devices can be in locations without easy access to power sources, enhancing flexibility in network design.
• Centralized Power Management: The switch provides centralized power management, allowing administrators to monitor and control the power supply to connected devices.

To enhance reliability, the switch supports a redundant power supply. In the event of a power supply failure, the redundant power supply seamlessly takes over, minimizing downtime and ensuring continuous operation. This feature is critical for networks where uninterrupted connectivity is imperative.

The Spanning Tree Protocol is a fundamental tool for preventing network loops and ensuring the stability of Ethernet networks. The SG350-52MP-K9-NA supports STP, providing a layer of redundancy by identifying and blocking redundant paths, preventing broadcast storms and network instability.

For organizations anticipating future growth and expansion, the stackable design of the SG350-52MP-K9-NA is a notable advantage. This allows multiple switches to be interconnected, forming a stack that operates as a single unit. Stackability simplifies management and enhances scalability as the network evolves.

Virtual Local Area Networks (VLANs) are essential for segmenting network traffic and improving overall network security. The SG350-52MP-K9-NA supports VLANs, enabling users to create isolated network segments for different departments or purposes within the organization.

With Gigabit Ethernet speeds, the SG350-52MP-K9-NA ensures high-performance data transfer. This is essential for businesses that demand swift and reliable data exchange, particularly in scenarios where large files or high-definition media content need to be transmitted across the network.

The Cisco SG350-52MP-K9-NA offers a range of manageability features that contribute to efficient network administration.

This switch supports Layer 3 routing, enabling it to make intelligent routing decisions based on IP addresses. This capability enhances network performance by allowing the switch to route traffic between different subnets. The Layer 3 functionality of the Cisco SG350-52MP-K9-NA adds a routing component to the switch, allowing it to make forwarding decisions based on IP addresses. This capability is essential for segmenting networks, improving overall efficiency, and enhancing security. The Layer 3 support makes the switch a versatile solution for businesses with complex networking requirements.

QoS is crucial for ensuring that critical applications receive priority in terms of bandwidth and network resources. The Cisco SG350-52MP-K9-NA allows administrators to configure QoS settings, ensuring optimal performance for essential applications. The switch incorporates advanced Quality of Service features to prioritize network traffic based on specific criteria. This ensures that critical applications receive the necessary bandwidth and guarantees a consistent level of service, even during periods of high network activity.

Security is a top priority in any network, and this Cisco switch incorporates several features to safeguard against unauthorized access and potential threats.

ACLs allow administrators to control traffic by defining rules for which packets are allowed or denied. This helps in preventing unauthorized access and securing the network from potential threats.

For secure remote management, the switch supports SSH and SSL encryption protocols. These protocols ensure that data transmitted between the administrator and the switch remains secure and protected from eavesdropping or tampering.

Port security features enable administrators to control access to the network by limiting the number of devices connected to a particular port. This helps prevent unauthorized devices from gaining access to the network.

The Cisco model is a 52-port Ethernet switch that is part of the Cisco SG350 series. It has 48 Gigabit Ethernet ports and four 10 Gigabit Ethernet SFP+ ports, and all of them support PoE+ (Power over Ethernet Plus). It also supports Layer 3 routing, which allows for more advanced network segmentation and traffic management. The switch is designed to be manageable, which means that it can be configured and monitored remotely.

In terms of performance, the SG350-52MP-K9-NA supports a switching capacity of 176 Gbps and a forwarding rate of 131.2 Mpps. The switch also supports jumbo frames, which allows for larger packet sizes and can improve performance in certain network environments.

In terms of reliability, the model supports features such as Link Aggregation Control Protocol (LACP) and Spanning Tree Protocol (STP) to prevent loops and ensure a stable network. It also supports Quality of Service (QoS) for prioritizing different types of traffic. The switch also has features like VLAN and Trunking, VRF-Lite, IPv6, and DHCP snooping and is protected by Cisco TrustSec and Advanced Malware Protection (AMP) security features to mitigate against attacks and ensure data privacy.

With the Power over Ethernet Plus feature, the switch can supply power to devices connected to it, which can reduce the need for separate power supplies and simplify the device.
