Enterasys SecureStack B3 B3G124-48P 48-port Gigabit PoE switch with 4 SFP slots.
The Enterasys SecureStack B3 B3G124-48P is a standalone 48-port Gigabit Ethernet switch with 10/100/1000Base-T copper ports plus 4 SFP expansion slots, and 375W of Power over Ethernet budget across the port count.
The SecureStack B3 range is a stackable L2/L3/L4 edge switch family supporting up to 768 policy rules per switch or stack, and is fully interoperable and stackable with Enterasys’s earlier B2 switches, making it a common upgrade path for existing Enterasys estates needing more PoE budget or port density.
This is a solid replacement or expansion unit for an existing Enterasys SecureStack estate. Tech-Star (UK-based, shipped worldwide) checks every switch before it ships. Get in touch to confirm compatibility with your specific SecureStack deployment.
