  • This 48-port Smart Gigabit PoE switch features 4x10G SFP+ uplink ports for flexible deployment in enterprise-grade networks. Equipped with robust security protocols, advanced QoS policies, and customizable VLAN configurations, it simplifies management while meeting the connectivity needs of hospitality venues, educational campuses, industrial facilities, and office networks.

    The switch integrates SmartLink power management, which intelligently prioritizes critical devices during power constraints by automatically disabling lower-priority PoE ports. This ensures uninterrupted operation of essential equipment while preventing system overloads. Designed for scalability, it provides a cost-effective backbone for small-to-medium businesses, combining high-density PoE support (up to 30W per port) with carrier-class redundancy and easy maintenance through an intuitive management interface.

    Hardened Departmental PoE Switch (IEC 61850-3)

    The Benchu Group SP7500 PoE Switch enables cost-effective office expansion by supporting IP telephony through Power over Ethernet (IEEE 802.3af/at compliant). Unlike traditional wired phone systems, this solution delivers both power and data via standard Ethernet cables, eliminating separate power wiring for VoIP phones. Enterprises can thus deploy an integrated voice/data/power network while significantly reducing infrastructure costs when migrating from legacy telephone systems.
