NETBuilder II specifications

The 3Com NETBuilder II is a robust networking solution designed to meet the requirements of enterprise-level organizations. Launched in the late 1990s, this platform was celebrated for its advanced features and high-performance capabilities. As a modular, multi-layer switch, it provides flexible configurations that allow businesses to scale their networks according to changing demands.

One of the standout features of the NETBuilder II is its support for both Layer 2 and Layer 3 switching. This dual functionality enables efficient data handling at various layers of the OSI model, allowing for improved network efficiency and reduced latency. With support for both Ethernet and Fast Ethernet, the device delivers high-speed connectivity to enhance data transmission rates across the network.

The NETBuilder II is equipped with a modular architecture, offering interchangeable line cards that facilitate customization according to specific network needs. This design allows organizations to start with basic configurations and expand their systems by adding additional modules as required.
