Description

The Cisco 550X SG550XG-48T is a Layer 2/Layer 3 stackable managed switch built for high-density 10 Gigabit access and aggregation. It suits small and mid-sized business networks, server and storage connectivity, and wiring-closet or data-closet deployments that need a scalable, resilient design.

It provides 48 x 10GBase-T copper ports plus 2 SFP+ combo uplinks and a Gigabit out-of-band management port. The architecture is wire-speed and non-blocking, with 960 Gbps switching capacity and a 714.24 Mpps forwarding rate. Up to 8 units can be stacked for up to 400 ports managed as a single system. The -AU suffix identifies the Australia/New Zealand power-cord variant. It uses an internal universal AC power supply (100-240V), is non-PoE, and needs no separate software licence or subscription.

Hybrid stacking is supported with SF550X, SG550X and SX550X models. The 2 combo SFP+ slots accept Cisco SFP and SFP+ modules, including MGBSX1, MGBLX1 and MGBT1.
