Black Box Corporation LGB5124A-R2 network switch 20 SFP 4 dual-media ports

24-port managed Gigabit switch

The Black Box LGB5124A-R2 is a rack-mountable managed switch with twenty SFP slots and four dual-media ports that accept either copper or fibre. It operates at Gigabit Ethernet speeds and supports both 1000Base-X and 10/100/1000Base-T technologies. Redundant power supply capability is included for improved uptime.

Network teams needing fibre uplinks

Suits administrators who want a compact 1U switch to aggregate multiple fibre links alongside a handful of copper connections. Layer 2 management features provide VLAN and traffic control for segmented networks. Buyers who require Layer 3 routing, PoE power delivery or stacking ports should evaluate other platforms.

Twenty SFP plus four combo ports

The twenty-four total Gigabit interfaces handle moderate aggregation tasks such as linking access switches or connecting servers to a fibre backbone. Four combo ports add flexibility when copper patching is preferred over transceivers. Environments that need higher port density, 10 Gbps uplinks or deeper buffer capacity will exceed the capabilities of this unit.
