3COM SWITCH 5500-EI PWR 28-PORT
Product Code: JE105A
- Product Description
E5500 HP E5500 switches deliver premium levels of performance, security, and reliability for robust switching at the enterprise network edge. The series consists of Layer 2/3/4 Fast Ethernet and Power over Ethernet switches, with advanced features that can accommodate the most demanding applications. They offer resilient and secure connectivity and the latest traffic-prioritization technologies to optimize applications on converged networks. Designed for maximum flexibility and scalability, they come with 24 or 48 10/100 ports, plus four active SFP-based Gigabit Ethernet ports for stacking and uplinks. They can be stacked up to eight units high in one location—or 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. Key features: - Enterprise-level performance; - High availability for critical applications; - Future-proof, standards-based switching; - Multi-layer security. Quality of Service (QoS) - Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues; - Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ; - Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums. Bandwidth shaping: - Rate limiting: provides per-port, ingress-based enforced bandwidth maximums; - Guaranteed minimums: provides per-port, per-queue egress-based guaranteed bandwidth minimums. Management - Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS; - Command-line interface (CLI): provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility; - SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices; - 3Com-heritage Comware V3 Operating System: CLI and Web user interface in common with HP E4XXX and E55XX series switches; - Port mirroring: enables traffic on a port to be simultaneously sent to a network analyzer for monitoring.
