Black Box LPB3028A – Managed PoE+ Switch 24-Port Gigabit + 4 SFP+

Product Overview

The Black Box LPB3028A is a managed PoE+ Gigabit Ethernet switch providing 24 x 10/100/1000 RJ-45 PoE+ ports and 4 x 100/1000 SFP+ uplink ports for high-density powered device deployments in commercial AV, enterprise networking, and access-layer infrastructure. With IEEE 802.3at PoE+ support on all 24 copper ports, the LPB3028A delivers sufficient power for IP cameras, wireless access points, VoIP phones, and commercial AV endpoints including network-connected displays and AV-over-IP devices. The full management suite provides IT and facilities teams the VLAN, QoS, and traffic-control tools needed to segment and prioritize AV and network traffic on a shared infrastructure.

Product Description

The LPB3028A is a fully managed Layer 2 Gigabit Ethernet switch built for access-layer deployments where a significant number of devices require both data connectivity and power over the same cable infrastructure. All 24 RJ-45 ports support IEEE 802.3at PoE+ (30W per port), making the LPB3028A well-suited for powering IP surveillance cameras, 802.11ac/ax wireless access points, commercial VoIP terminals, and AV-over-IP endpoints such as KVM extender receivers and AV matrix nodes. The four SFP+ uplink slots accept 100BASE-FX or 1000BASE-X fiber or copper transceiver modules, providing flexible connectivity to distribution or core switches over fiber or extended copper runs. Managed functionality includes IEEE 802.1Q VLAN tagging for traffic segmentation, QoS priority queuing for latency-sensitive AV streams, port-based access control, and SNMP monitoring for integration into enterprise network management platforms. The rack-mount form factor and standard 19-inch chassis fit directly into network closets, AV equipment racks, or server room enclosures. For integrators designing AV-over-IP systems, the LPB3028A provides the Layer 2 switching foundation required by multicast-based AV distribution protocols, with IGMP snooping available for controlling multicast traffic to specific ports. Commercial meeting spaces, multi-purpose rooms, and house of worship installations with distributed powered endpoints benefit from the LPB3028A's combination of PoE+ density and management depth. Creation Networks supplies AV networking infrastructure including managed switches, PoE injectors, and structured cabling components at creationnetworks.net.

Key Features

• 24 x PoE+ RJ-45 Ports — IEEE 802.3at PoE+ (30W per port) on all 24 copper ports powers IP cameras, WAPs, AV endpoints, and VoIP devices.
• 4 x SFP+ Uplink Ports — 100/1000 SFP+ slots accept fiber or copper transceiver modules for flexible uplink connectivity to core or distribution switches.
• Full Layer 2 Management — IEEE 802.1Q VLANs, QoS, port-based access control, and SNMP management for enterprise-grade network administration.
• IGMP Snooping — Controls multicast traffic distribution, critical for AV-over-IP deployments using multicast streaming protocols.
• Gigabit on All Copper Ports — 10/100/1000 auto-negotiation on each RJ-45 port ensures full gigabit throughput to all connected devices.
• Rack-Mount Form Factor — Standard 19-inch 1U chassis fits directly into network closets, AV racks, or server rooms.
• SNMP Management — Integrates with existing network management systems for centralized monitoring and configuration.
• Traffic Prioritization (QoS) — Configurable QoS queues ensure latency-sensitive AV and voice traffic receives priority over bulk data flows.
