Cisco Business CBS220-48T-4X Full English Product Description

1. Product Overview

Model Suffix Definition

• 48: 48×10/100/1000BASE-T non-PoE copper access ports
• T: Data-only RJ45 ports without PoE power supply
• 4X: Four dedicated 10G SFP+ uplink slots, backward compatible with 1G SFP transceivers and 10G DAC cables
  No "-E/D" suffix means it adopts standard 19-inch 1RU metal rack chassis with integrated internal universal AC power supply, eliminating the need for an external desktop power adapter.
  This web-managed wire-speed non-blocking switch connects mass office PCs, printers, large-capacity NAS storage and non-powered wireless APs. Equipped with four 10G high-bandwidth uplinks, complete enterprise-grade Layer 2 functions, advanced QoS and multi-layer security, it serves as a scalable managed core access switch for growing SMBs with future high-bandwidth upgrade demands.
