The NETGEAR GSM7328FS is a Layer 3 managed switch delivering non-blocking, wire-speed throughput across 24 fiber Gigabit ports. Built on the ProSafe M5300 platform, this 1U rack-mountable unit combines high-density SFP connectivity with four combo RJ45 ports and four modular expansion bays for 10 Gigabit uplinks. It supports stacking of up to 8 units with 48 Gbps bi-directional ring topology, enabling single IP management across the entire stack.
