Description
The 3Com 3C17516 is a high-performance LAN expansion module specifically engineered for the 3Com 8800 Series Switch platform. This module significantly boosts the port density and bandwidth capabilities of the 8800 switch by adding twenty-four ports that support the 10/100/1000Base-T standards. This means each port can operate at 10 Mbps, 100 Mbps, or a full Gigabit Ethernet speed of 1000 Mbps, providing exceptional flexibility and performance for a wide range of network devices. Designed for deployment in demanding network environments, the 3C17516 is ideal for use in the core or distribution layers of an enterprise network. Its high-density configuration allows for the connection of numerous servers, workstations, IP phones, and other network endpoints requiring high-speed access. The auto-negotiation feature on each port ensures seamless integration with devices operating at different speeds and duplex modes, simplifying network setup and management. The module's ability to deliver Gigabit speeds to end devices dramatically improves application performance, reduces latency, and increases overall network efficiency. As an expansion module, the 3C17516 leverages the robust chassis and management capabilities of the 3Com 8800 Series Switch. This allows for centralized control and monitoring of all ports on the module, ensuring consistent network policies and simplified administration. The addition of this module provides a scalable and cost-effective way to upgrade network capacity and performance, supporting the growing demands of modern businesses for bandwidth and connectivity.
