The C9300-48U-A is a 48-port Cisco Catalyst 9300 series L3 managed switch. It is designed for enterprise and campus networks that require high-performance, secure, and feature-rich access switching.
It is built on the Cisco Unified Access Data Plane (UADP) 2.0 application-specific integrated circuit (ASIC) and is optimized for security, IoT, and mobility. The switch is also equipped with several advanced technologies such as:
- Cisco DNA software and Cisco SD-Access
- Advanced security features include Cisco TrustSec, Identity Services Engine (ISE), and Advanced Malware Protection (AMP)
- Cisco DNA Center Assurance is a network assurance platform that provides proactive network health monitoring and troubleshooting, with real-time visibility and remediation across the entire network.
- Support for Application Visibility and Control (AVC), which provides deep packet inspection and granular visibility into application traffic.
- Support for Cisco EnergyWise, which enables IT to monitor, measure, and reduce energy consumption across the network.
The switch also provides investment protection by delivering next-generation performance and capabilities while supporting existing network and security infrastructure.
The C9300-48U-A offers 48 Gigabit Ethernet ports (48 x 10/100/1000Mbps), 4x 40G or 8x 10G uplink and stacking ports, providing high-speed connectivity to support bandwidth-intensive applications like video, virtualization, and cloud services.
Robust Security and Dynamic Quality
The Cisco Small Business SG350XG-24T-K9 is a high-performance managed switch designed for small businesses. It offers robust security features and dynamic quality of service (QoS) to ensure optimal network performance.
The switch provides advanced security features such as access control lists (ACLs), port security, and 802.1x authentication to protect against unauthorized access and network breaches. It also offers advanced threat detection and mitigation capabilities to prevent malware and other malicious attacks.
The switch also features dynamic QoS, which automatically prioritizes network traffic based on the type of application or service being used. This ensures that mission-critical applications and services have priority over less important traffic, resulting in a more efficient and reliable network.
The SG350XG-24T-K9 also has 24 Gigabit Ethernet ports, which provide high-speed connectivity for devices and servers. It also supports link aggregation, allowing multiple ports to be grouped together for increased bandwidth and redundancy.
This model Cisco Catalyst 9300 48 Ports Ethernet Switch is a highly reliable network switch designed for enterprise-level environments. The switch is built with a modular architecture, which allows for easy upgrades and maintenance. This helps to ensure that the switch remains operational and secure over its lifespan.
The switch also features advanced hardware redundancy and failover mechanisms, which help to prevent network downtime and outages. This includes dual, hot-swappable power supplies and fans, as well as redundant management modules. Additionally, the switch supports Cisco StackWise-480 technology, which allows for up to nine switches to be stacked together, providing even more redundancy and resiliency.
In terms of software, the C9300-48U-A switch runs on Cisco IOS XE software, which is known for its stability and robustness. The switch also includes advanced security features, such as Cisco TrustSec, which provide end-to-end security and compliance through a simplified and automated security framework.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
