The certified refurbished 3Com Baseline Plus Switch 2928-PWR Plus (Model 3CRBSG28HPWR93) features 24 auto-sensing 10/100/1000BASE-T Gigabit Ethernet ports (RJ-45), 4 dedicated Gigabit SFP fibre uplink ports, 365W IEEE 802.3af Power over Ethernet budget, 56 Gbps switching capacity, 41.7 Mpps forwarding rate, and store-and-forward switching architecture, delivering enterprise-class Layer 2/3 managed networking with advanced security and voice-ready capabilities for small to medium business environments requiring reliable, high-performance infrastructure.

Ideal Use Cases

This professionally restored managed switch excels in environments demanding robust networking with Power over Ethernet capabilities. Deploy this versatile switch to power and connect VoIP phone systems, wireless access points, and IP security cameras through a single cable infrastructure, eliminating costly separate power installations. Perfect for expanding small business networks, upgrading aging infrastructure, creating voice-ready converged networks, or building secure multi-VLAN environments for educational institutions, professional offices, healthcare facilities, and retail locations requiring enterprise-grade features without enterprise pricing.

Key Features and Benefits

Enterprise-Class Connectivity: 24 auto-sensing Gigabit Ethernet ports with auto MDI/MDIX deliver non-blocking wire-speed performance across all 28 ports, eliminating network bottlenecks whilst four dedicated SFP fibre uplink ports enable long-distance backbone connections and high-bandwidth aggregation to network cores.

Comprehensive PoE Delivery: Industry-standard IEEE 802.3af compliance with 365W total power budget and pre-standard PoE Plus support delivers up to 30W per port, providing flexible power-and-data delivery to connected devices with per-port and per-unit enable/disable control for precise power management.

Advanced Layer 2 Switching: Support for 256 port-based VLANs (IEEE 802.1Q), IEEE 802.3ad LACP link aggregation with automated trunk formation supporting up to 8 ports per trunk, and four hardware queues per port with IEEE 802.1p CoS/QoS ensures optimal traffic prioritisation and network segmentation for demanding applications.

Voice-Ready Network Features: Auto-voice VLAN technology automatically segregates and prioritises VoIP traffic from any vendor without manual configuration, whilst QoS capabilities guarantee consistent call quality and IGMP snooping v1/v2/v3 optimises multicast traffic for efficient bandwidth utilisation.

Enterprise-Grade Security: IEEE 802.1X network login authentication controls access at each port, MAC-based Layer 2 ACLs and IP-based Layer 3 ACLs provide granular traffic filtering, time-based policy enforcement adds scheduling capabilities, and HTTPS encryption secures all management communications.

Flexible Management Options: Web-based graphical interface with intuitive switch and port visualisation, SNMP v1/v2c/v3 support, RMON alarm and event monitoring, CLI access via front-mounted RS-232 console port, and compatibility with 3Com IMC platform deliver management flexibility for users of all skill levels.

Reliable Performance Architecture: Store-and-forward switching method with 8,192 MAC address table entries, jumbo frame support up to 10K bytes, IEEE 802.1D/802.1w Spanning Tree Protocol support, 32 static routes, 8 virtual VLAN interfaces, and DHCP relay capabilities provide robust, reliable network operations.

Comprehensive Diagnostics: Built-in cable diagnostics troubleshoot copper connectivity issues, ping and traceroute utilities verify network paths, port mirroring enables traffic analysis, and power/fan/temperature alarms with system logging provide proactive monitoring capabilities.

Certified Refurbishment and Quality Assurance

All certified refurbished 3Com Baseline Plus Switch 2928-PWR Plus units sold by Reboot IT undergo comprehensive professional restoration using cutting-edge testing software developed through decades of industry expertise. Since 2001, Reboot IT has established itself as Australia's premier refurbished networking specialist, bringing over two decades of professional experience to every device restoration.

Each switch is thoroughly tested across all features and functions, including comprehensive port testing, PoE validation and power budget verification, switching capacity and forwarding rate analysis, VLAN configuration and traffic segmentation testing, thermal stress testing under sustained loads, and firmware verification to ensure optimal performance. All worn or faulty components are replaced exclusively with quality parts, and every unit receives professional cleaning and detailed cosmetic grading before certification.

Understanding Cosmetic Grades

Excellent Grade units display minimal signs of previous use with only light surface marks barely visible upon close inspection, maintained housing integrity, and professional appearance suitable for client-facing environments.

Good Grade units show more visible signs of use including light scratches on the chassis, minor surface wear, or small cosmetic imperfections on the case, whilst maintaining complete functionality and identical performance to Excellent grade units at a more accessible price point.

Regardless of cosmetic grade, all units deliver identical enterprise-class performance, reliability, and warranty protection.
