Product Description

The Cisco Small Business 300 Series SG300-28SFP switch offers reliable fiber connectivity with 26 dedicated SFP ports and 2 combo mini-GBIC slots, allowing for versatile network configurations. It's built to handle the demands of mid-sized networks, supporting both switching and Layer 3 routing functions.

Often found in small to medium enterprises, the SG300-28SFP streamlines network management while maintaining high performance over fiber links. IT professionals and network administrators benefit from its manageable interface and flexible deployment options.

Key Features

  • Comprehensive fiber connectivity with 26 fixed SFP ports and 2 combo slots for uplinks or additional fiber connections
  • Layer 3 capabilities provide advanced routing between VLANs and networks
  • Supports Gigabit Ethernet speeds for fast data transfer and reliable performance
  • Rack-mountable 1U form factor fits standard network cabinets and racks
  • Managed switch functionality enables detailed network control and monitoring

This switch is commonly deployed in network closets of office buildings and data centers where fiber optic connectivity is essential. It handles the backbone traffic efficiently and simplifies inter-VLAN routing without requiring a separate router.

By integrating the SG300-28SFP, networks achieve better scalability and fiber-based communication, which is vital for businesses relying on stable and fast connections across multiple floors or buildings.


Use Cases

The Cisco SG300-28SFP-K9 is commonly deployed in environments where high-density fiber connectivity and advanced Layer 3 routing are critical. It is ideal for SMBs and distributed enterprise networks that require efficient rack-mounted switches to support fiber-based aggregation or access layers.

How It's Used:

  • Aggregating fiber links in campus network closets for SMBs requiring scalable Gigabit connections.
  • Serving as a Layer 3 routing switch in remote office setups to manage inter-VLAN traffic efficiently.
  • Integrating with storage area networks (SAN) where fiber optic connections are essential for performance and reliability.
  • Supporting edge computing deployments by providing flexible uplink options and fiber connectivity in a compact form factor.
  • Facilitating network segmentation and access control in enterprise branch offices with managed Layer 3 capabilities.

This switch enhances operational efficiency by consolidating fiber connectivity and routing functions into a single rack-mountable unit. Its design supports future scalability demands and reduces network complexity in fiber-reliant infrastructures.
