Cisco SG550XG-48T-K9 550X Series 46+2 Port 10GBase-T 960Gbps Stackable Layer 3 Switch

The Cisco SG550XG-48T-K9 is a stackable managed switch from the 550X Series, built for growing businesses needing affordable, high-density 10 Gigabit Ethernet connectivity. It sits at the top of the copper-heavy 10GE tier: the 48T model doubles the port density of the SG550XG-24T (480 Gbps, 24 ports) while offering true copper connectivity the fiber-based SG550XG-24F sibling lacks. It provides 46 fixed 10GBase-T copper ports alongside 2 combo ports, each pairing a copper port with an SFP+ slot where only one interface is active at a time, plus a dedicated Gigabit Ethernet out-of-band management port. The switch delivers 960 Gbps of switching capacity and 714.24 Mpps of forwarding, wire-speed and nonblocking across all ports. It supports up to 7,168 IPv4 routes and 1,792 IPv6 routes, 4,094 VLANs, and true hardware stacking of up to 8 units managed as a single system with up to 400 total ports. An 800MHz dual-core ARM processor with 512MB of memory powers the switch, backed by hardware redundancy across dual power inputs and 4+1 redundant fans.
