SG220-50P-K9-NA-RF

SG220-50P 50Port GigabitPoE Smart Switch REMANUFACTURED

In Stock

Inventory quantities are subject to availability and are not guaranteed until the order is placed.

SG220-50P-K9-NA-RF is a professionally remanufactured Cisco SG220-50P 50-Port Gigabit PoE Smart Switch, designed to provide managed switching capabilities with Power over Ethernet for small to medium-sized business networks. With 48 Gigabit Ethernet PoE ports and 2 combo SFP uplink ports, this switch delivers centralized power and data connectivity for IP phones, wireless access points, and IP cameras without requiring separate power infrastructure.

This remanufactured smart switch meets Cisco performance specifications and has been thoroughly inspected and tested prior to shipment. Validation includes PoE power delivery across all 48 ports, uplink SFP port functionality, and full web-based management interface operation.

Key Features:
• 48 Gigabit Ethernet RJ-45 ports with IEEE 802.3af/at PoE support and 375W total PoE power budget
• 2 combo mini-GBIC SFP uplink ports for flexible fiber or copper uplink connectivity
• Web-based GUI and CLI management with support for VLANs, QoS, and access control lists
• IEEE 802.1Q VLAN tagging with support for up to 256 active VLANs for network segmentation
• Energy Efficient Ethernet (IEEE 802.3az) support for reduced power consumption on inactive links
• Fanless design with a switching capacity of 100 Gbps and forwarding rate of 74.4 Mpps

This switch is ideal for IT administrators, network engineers, and small business owners deploying VoIP, wireless, or surveillance infrastructure who need reliable PoE switching at scale. Choosing a remanufactured Cisco SG220-50P-K9-NA-RF delivers the proven performance and feature set of Cisco Smart Switch technology at a significantly reduced cost compared to purchasing new, making it a smart investment for budget-conscious deployments without sacrificing reliability or functionality.
