Cisco SG350X-48P-K9 48-Port Gigabit PoE Stackable Managed Switch

The Cisco SG350X-48P-K9 is a 48-port Gigabit Ethernet PoE stackable managed switch designed for Cisco network systems in enterprise environments where high-density, power-enabled connectivity is required. It provides 48x RJ-45 PoE ports plus 4x 10-Gigabit SFP+ uplinks, offering scalable access-layer networking with built-in Power over Ethernet (IEEE 802.3af/at) and a PoE budget up to 382 Watts. With a switching capacity of up to 176 Gbps and forwarding rate up to 130.95 Mpps, it supports fast network expansion while maintaining performance in busy office, campus, healthcare, retail, or industrial settings. The switch supports Layer 2 and Layer 3 Lite features, enabling efficient traffic management and basic routing, alongside security controls such as ACLs, 802.1X, and port security. It is rack-mountable in 1U and uses an internal AC power supply for straightforward deployment. Management is via Web GUI, CLI, and SNMP, and it supports VLANs for segmented networks. Its stackable architecture allows you to grow the network by adding switches while preserving centralized configuration and simplified administration. Common replacements include Cisco CBS350-48P-4X, Cisco C9200L-48P-4X, and Cisco SG550X-48P.
