Cisco 2x 1GbE SFP 4x 10GbE SFP+ Single AC PSU 19-inch Rack-mountable 1U Network Switch – N520-4G4Z-A

Cisco N520-4G4Z-A 1U SFP and SFP+ Network Switch

The Cisco N520-4G4Z-A is a compact 1U rack-mountable network switch designed for installations that prioritize fiber-based connectivity and a clean, space-efficient equipment layout. Its configuration includes two 1GbE SFP ports and four 10GbE SFP+ ports, creating a focused mix of standard and higher-speed optical interfaces for aggregation, access, or transport applications. A single AC power supply is identified in the listing, while the 19-inch rack format supports straightforward placement in standard network cabinets. This port profile is particularly useful for deployments that need a small switch with dedicated SFP-family interfaces instead of a large copper access footprint.
