Key Features & Benefits

1. Fiber-Centric Connectivity

  • 24 x 1G SFP Ports: Dedicated fiber ports for long-distance, interference-resistant connections. Supports standard 1G SFP transceivers (single-mode/multimode).

  • No PoE: Designed for non-PoE environments, focusing on pure data switching and aggregation.

  • Long-Range Deployment: Eliminates distance limits of copper cabling, perfect for campus backbones and industrial sites.

2. Modular & Scalable Uplinks

  • 1 x Modular Uplink Slot: Supports high-speed modules (e.g., C9300-NM-2Y, C9300X-NM-8Y) for 10G/25G fiber uplinks.

  • StackWise-480: Stack up to 8 switches for 480 Gbps stacking bandwidth, unifying management and scaling capacity.

  • StackPower: Supports power supply sharing across the stack for N+1 redundancy.

3. High Performance & Security

  • UADP 2.0 ASIC: Delivers wire-speed performance and advanced security/QoS capabilities.

  • Security: Includes MACsec-256 encryption, Secure Boot, and ACLs for data protection.

  • Quality of Service (QoS): 8 egress queues, DSCP/CoS classification, and prioritization for voice/video.

  • Jumbo Frames: Supports up to 9198 bytes for efficient large-file transfers.

4. Intelligent Management

  • Cisco DNA Essentials: Automation, telemetry, and simplified monitoring via Cisco DNA Center.

  • Cisco IOS XE: Programmable OS with support for NETCONF/YANG and model-driven management.

  • Non-Stop Forwarding (NSF/SSO): Sub-50ms failover in stacks for zero downtime.
