Cisco SG102-24-NA Ethernet Switch 2 x Expansion Slots SFP Refurbished

The Cisco SG102-24-NA is an Ethernet switch designed for small and medium-sized businesses. It has 24 Gigabit Ethernet ports and two mini-GBIC (SFP) ports for fiber connectivity. The switch supports both wire-speed Layer 2 switching and basic Layer 3 routing and includes advanced security and management features such as Quality of Service (QoS), Advanced Security, and IPv6 support. Additionally, the managed switch can be remotely using a web browser or the Cisco Smart Network Application (SNA) software, making it easy to monitor and configure the switch from anywhere on the network.

The switch's support for 10/100/1000Base-T ensures high-speed data transfer, meeting the demands of modern networking applications. This capability is especially crucial in environments where large volumes of data need to be transmitted quickly and efficiently. The Cisco SG102-24-NA's performance is further enhanced by its 24 ports, which can handle simultaneous connections without compromising speed or stability.

One notable feature of the Cisco SG102-24-NA is its 2 expansion slots, enhancing its scalability and adaptability to evolving network requirements. These expansion slots open up possibilities for additional modules or features, allowing businesses to tailor the switch to their specific needs. Whether it's for increased bandwidth, specialized connectivity options, or enhanced security features, the expansion slots provide room for growth and customization.

Cisco understands the importance of user-friendly interfaces in networking equipment. The SG102-24-NA is equipped with features that simplify the management of the switch. This includes an intuitive web-based interface that allows administrators to configure settings, performance, and issues with ease. Additionally, the switch supports SNMP (Simple Network Management Protocol), facilitating integration with network management systems for centralized control.

Cisco emphasizes sustainability, and the SG102-24-NA is designed with energy efficiency in mind. The switch incorporates features such as Energy-Efficient Ethernet (EEE) and a fanless design, reducing power consumption and minimizing its environmental impact. This not only benefits businesses looking to reduce energy costs but also aligns with the growing emphasis on eco-friendly practices.

The primary function of the Cisco SG102-24-NA is to provide connectivity for up to 24 devices within a network. These ports can accommodate various devices such as computers, printers, servers, and other networking equipment.

The inclusion of two Combo Mini-GBIC ports adds versatility to the switch. Mini-GBIC (Gigabit Interface Converter) ports support different types of transceivers, allowing for the connection of devices using fiber-optic or copper interfaces. This flexibility is essential for adapting to diverse networking requirements.

With 22 ports utilizing RJ-45 connectors, the switch ensures compatibility with standard Ethernet cables. This makes it easy to integrate the Cisco SG102-24-NA into existing network infrastructures without the need for specialized cabling.

The two expansion slots provide room for future scalability and customization. Users can add modules or interfaces to enhance the switch's capabilities, adapting it to evolving network needs.

The switch supports Gigabit Ethernet, which means it can transmit data at speeds of 10, 100, and 1000 Mbps. This high-speed capability is crucial for handling bandwidth-intensive applications and facilitating fast data transfer within the network.

Designed to be rack-mountable, the Cisco SG102-24-NA optimizes space utilization in network infrastructure setups. This feature is particularly beneficial for data centers and server rooms where efficient use of space is paramount.

The switch likely supports Virtual Local Area Networks (VLANs), allowing users to segment the network for improved security and efficiency. VLANs help control broadcast domains and enhance network organization.

QoS features enable users to prioritize certain types of network traffic. This is beneficial for ensuring that critical applications receive the necessary bandwidth, enhancing overall network performance.

Port security features can be configured to control access to specific ports based on MAC addresses. This helps prevent unauthorized devices from connecting to the network.

The Cisco SG102-24-NA is a high-performance switch that is capable of delivering wire-speed performance on all of its ports. This means that it can handle the full-duplex traffic at the maximum speed of each port, which is 1 Gbps for the Gigabit Ethernet ports. It uses a non-blocking switching architecture that allows it to forward and filter packets at full line rate without any packet loss.

Additionally, the Cisco part has a high packet forwarding rate, which means that it can process and forward a large number of packets per second. The exact forwarding rate will depend on the packet size and the mix of traffic, but generally, it can support a high number of concurrent connections.

In terms of latency, the Cisco model is designed to minimize delay in packet forwarding, thus it ensures low latency which is good for real-time applications like VoIP, Video Streaming, and Gaming.

The Cisco SG102-24-NA is designed for reliability, it has several features that help ensure that it can continue to operate in case of a failure. Some of these features include:

• Redundant Power Supplies: The switch has dual power supply capabilities, which means that if one power supply fails, the other can take over, keeping the switch operational.
• IEEE 802.3ad Link Aggregation Control Protocol (LACP) support: It supports Link Aggregation which allows you to bundle multiple physical links together to form a single logical link, increasing the bandwidth and providing redundancy.
• Quality of Service (QoS): The switch can prioritize different types of traffic so that critical applications like VoIP and video conferencing have priority over less-critical traffic. This helps ensure that the switch can continue to provide reliable service even when the network is congested.
• Advanced Security: The switch includes several advanced security features such as Access Control Lists (ACLs) and Network Admission Control (NAC) to protect against unauthorized access and malware, which helps to ensure that the switch continues to operate securely.
• Remote Management: The switch can be managed remotely using a web browser or the Cisco Smart Network Application (SNA) software, allowing you to monitor the switch from anywhere on the network.
