Cisco Catalyst 9300L-48P-4G-E POE+

Cisco Catalyst 9300L-48P – High-Performance 48-Port PoE+ Managed Switch for Modern Enterprise Networks

The Cisco Catalyst 9300L-48P is a next-generation managed switch tailored for enterprises that require a reliable, scalable, and secure network infrastructure. Designed to support high-density environments, this switch boasts 48 Gigabit Ethernet ports with Power over Ethernet Plus (PoE+), making it ideal for powering a wide array of network devices such as IP phones, wireless access points, surveillance cameras, and other PoE-enabled equipment.

Advanced PoE+ Power Management

One of the standout features of the Cisco Catalyst 9300L-48P is its robust PoE+ capability. Each port can deliver up to 30 watts of power, ensuring that even the most demanding devices receive sufficient power without requiring additional electrical wiring. The switch also supports Cisco’s intelligent power management system, which optimizes power allocation based on device needs, reducing overall power consumption and increasing energy efficiency.

High-Speed Connectivity and Uplink Options

With 48 Gigabit Ethernet ports, the Cisco Catalyst 9300L-48P provides fast and reliable connections for end devices across the network. It also includes 4 fixed 1 Gigabit SFP uplink ports, enabling high-speed connections to core network components or data centers. These uplinks support fiber optics, allowing long-distance data transmission with minimal latency and high throughput.

Enhanced Security Features

Security is a critical concern for modern enterprises, and Cisco addresses this with a comprehensive suite of features on the 9300L-48P. The switch supports IEEE 802.1X port-based network access control, which authenticates devices before they can access the network. Other security mechanisms include dynamic ARP inspection, DHCP snooping, and IP Source Guard, which protect against common network attacks such as ARP spoofing and IP address theft.

Additionally, the switch supports encrypted traffic analytics and segmentation through VLANs, helping to isolate sensitive data and control traffic flow effectively. Integration with Cisco Identity Services Engine (ISE) enhances network policy enforcement and simplifies compliance management.

Scalability and StackWise Technology

For enterprises that require growth and flexibility, the Cisco Catalyst 9300L-48P supports StackWise stacking technology. Up to eight switches can be interconnected and managed as a single logical unit, simplifying network management and improving redundancy. StackWise technology provides high availability and seamless failover capabilities, which minimizes downtime and ensures continuous network operation.

Advanced Layer 3 Routing

Beyond traditional Layer 2 switching, the Cisco Catalyst 9300L-48P offers comprehensive Layer 3 routing capabilities. It supports static routing and dynamic routing protocols such as OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol). These routing functions enable efficient traffic management and route optimization within complex enterprise networks.

Multicast routing protocols, including PIM (Protocol Independent Multicast), are also supported, which is essential for applications such as video conferencing and streaming.

Simplified Network Management with Cisco DNA Center

Managing a large-scale network can be challenging, but Cisco simplifies this process with the integration of Cisco DNA Center. This centralized management platform offers automation, analytics, and assurance, enabling network administrators to provision devices, monitor performance, and troubleshoot issues proactively. With Cisco DNA Center, the Catalyst 9300L-48P fits perfectly into Cisco’s intent-based networking strategy, providing agility and visibility into network operations.

Energy Efficiency and Environmental Considerations

The Cisco Catalyst 9300L-48P is engineered with energy-saving technologies such as Energy Efficient Ethernet (EEE) and intelligent power management. These features help reduce operational costs by lowering power consumption without sacrificing performance or reliability. The hardware is also designed to operate reliably in various environmental conditions, ensuring robust performance in both data centers and enterprise campus environments.

Ideal Applications and Use Cases

The Cisco Catalyst 9300L-48P switch is particularly well-suited for enterprise campus networks, branch offices, and data centers that demand high port density and reliable PoE+ support. Its security features and scalability make it an excellent choice for organizations focused on secure and manageable networks that can adapt to evolving business needs.

Whether it’s supporting voice over IP (VoIP) phones, wireless access points, or IP surveillance systems, the Catalyst 9300L-48P provides the necessary performance and reliability to keep business-critical applications running smoothly.

In summary, the Cisco Catalyst 9300L-48P is a powerful, versatile managed switch that delivers high-speed connectivity, advanced security, and efficient power management. Its scalable design and comprehensive management features make it an ideal solution for enterprises aiming to build future-proof networks that support a broad range of applications and devices.
