Product Description

The Cisco 500 Series SG500-52P-K9 is a Layer 3 managed switch designed to handle demanding network environments. It offers 48 PoE+ ports suitable for powering IP phones, wireless access points, and other network devices directly through Ethernet. Often found in medium-sized businesses or branch offices, this switch provides reliable Gigabit Ethernet connections and flexible fiber uplink options through its combo and dedicated SFP ports.

Built for network administrators who need both performance and ease of management, this switch supports stacking so multiple units can be managed as one, simplifying network expansion. It’s commonly used in setups requiring robust power delivery alongside high-speed data transmission.

Key Features

  • 48 ports deliver Power over Ethernet Plus to power devices without extra cabling
  • Flexible uplink options via 2 combo SFP and 2 SFP ports for fiber connections
  • Layer 3 routing capabilities enable efficient traffic management within networks
  • Stackable design allows multiple switches to work as a single unit
  • Gigabit Ethernet ports ensure fast and stable data transfer across devices

This switch is typically deployed in office environments, schools, or retail locations where multiple powered devices and fast, reliable network connections are essential. It helps keep networks organized and manageable while meeting the power needs of connected equipment.


Use Cases

The Cisco SG500-52P-K9 switch is designed for mid-sized enterprise networks requiring robust PoE+ support combined with advanced Layer 3 features. It is particularly suited for environments where scalable stacking, high port density, and flexible fiber uplink connectivity are essential for managing converged data and voice traffic efficiently.

How It's Used:

  • Deploying in enterprise campus networks to power IP phones, wireless access points, and security cameras through PoE while maintaining high-performance segmented routing.
  • Utilizing in SMB data centers for aggregating virtualized server connections with scalable stacking to simplify network expansion and management.
  • Implementing in remote or branch offices requiring secure Layer 3 routing capabilities alongside PoE support for VoIP and surveillance systems.
  • Supporting edge computing nodes with high port density and fiber uplinks for low-latency access to distributed applications and services.
  • Integrating into storage clusters where dedicated fiber SFP ports ensure reliable high-speed connectivity and redundancy.

This switch enhances operational efficiency by consolidating PoE power delivery and Layer 3 routing into a scalable platform, enabling organizations to manage complex network topologies with simplified administration while supporting growth and performance demands.
