3Com Switch 5500-EI PWR 28-Port 10/100, PoE (Power over Ethernet) P/N: 3CR17171-91

The 3Com® Switch 5500 10/100 Family delivers premium levels of performance, security and reliability for robust switching at the enterprise network edge. The family consists of Layer 2/3/4 Fast Ethernet and Power over Ethernet switches, with advanced features that can accommodate the most demanding applications, offering resilient and secure connectivity and the latest traffic-prioritization technologies to optimize applications on converged networks. Designed for maximum flexibility and scalability, 3Com Switch 5500 models come with 24 or 48 10/100 ports, plus four active SFP-based Gigabit Ethernet ports for stacking and uplinks.

The switches can be stacked up to eight units high in one location, or they can be distributed over several sites up to 70 km (43.5 miles) apart and connected via Gigabit links to form a virtual “stack.” One stack can provide up to 384 Fast Ethernet ports and may be managed centrally as a single-IP entity. Each stack offers chassis-like availability and resiliency over traditional aggregated-trunk configurations with patented 3Com XRN® (eXpandable Resilient Networking) stacking technology.

Further expansion is possible via clustered stacking technology, allowing single IP management for up to 32 devices from different 3Com switch families, including the Switch 5500G, 5500, 4800G, 4500G, 4500, 4210 and 4200G.
