Frequently Asked Questions
What is the primary power capacity of the Cisco C9300-48U-A? +
The C9300-48U-A is designed for high-density environments, featuring 48 ports of UPoE (Universal Power over Ethernet). This capability allows the switch to deliver up to 60W per port, making it an ideal solution for powering advanced endpoints like high-definition IP cameras, multi-radio wireless access points, and sophisticated IoT devices that require more power than standard PoE+ can provide.
Can the C9300-48U-A operate in a stacking configuration? +
Yes, this model supports Cisco StackWise technology, which allows you to group multiple switches into a single logical unit. This provides higher bandwidth and simplified management across your access layer. By stacking these units, you increase the resilience of your network infrastructure while maintaining a consistent operational experience for your IT staff through a unified management interface.
Does the C9300-48U-A support Layer 3 routing protocols? +
The C9300-48U-A is a high-performance Layer 3 switch. It supports advanced routing protocols, including OSPF, EIGRP, and BGP, along with robust multicast and policy-based routing features. This ensures that your network can handle complex traffic flows and inter-VLAN routing with low latency, providing the necessary intelligence for modern enterprise campus environments.
What software license level is included with the C9300-48U-A? +
This specific SKU comes with the Network Advantage license. This enterprise-grade license provides a comprehensive set of features, including advanced security, full Layer 3 routing capabilities, and support for Cisco's Software-Defined Access (SD-Access) architecture. It is designed for businesses looking to implement a highly automated and secure network fabric that scales with their growing operational demands.
How does the C9300-48U-A manage network security? +
Security is integrated at the hardware level with Cisco Trust Anchor Technologies. The switch supports advanced security features such as MACsec-128 encryption, IEEE 802.1X, and integrated threat defense. These capabilities allow network administrators to enforce strict identity-based access control and protect data integrity, ensuring that both wired and wireless traffic remain secure from edge to core.
What kind of management interface does this switch offer? +
The switch offers flexible management options, including a web-based GUI for intuitive configuration and a standard CLI for granular control. It is also fully compatible with Cisco DNA Center, enabling centralized orchestration, automation, and real-time telemetry. This versatile management ecosystem helps reduce the time spent on manual configuration and accelerates the deployment of new network services.
Can the C9300-48U-A be integrated into existing rackmount environments? +
Yes, the C9300-48U-A is designed for standard 19-inch rack deployment. Its compact 1RU form factor allows for efficient use of rack space in high-density data closets. It also features front-to-back cooling, ensuring it aligns with industry-standard thermal management practices for server rooms and wiring closets where space and airflow optimization are critical for hardware longevity.
Is this switch compatible with multi-gigabit copper cabling? +
The 48 ports on this model are 10/100/1000BASE-T Ethernet interfaces. They provide reliable, high-speed connectivity for standard Cat5e or Cat6 cabling infrastructure. While they do not support multi-gigabit (2.5G/5G) speeds, they provide excellent performance for standard gigabit endpoints, making them a cost-effective choice for general office connectivity and standard desktop user requirements.
