1.2 NBR FEATURES

LANVIEW LEDs

Cabletron Systems provides a visual diagnostic and monitoring system, called LANVIEW, with the NBR. LANVIEW LEDs help you quickly identify device, port, and physical layer problems.

LCD

The NBR-420 and NBR-620 are equipped with an LCD that provides information about the NBR such as power up diagnostics, revision levels, MAC and IP addresses, and error alerts.

RESET Button

The RESET button lets you re-boot and initialize the processor.

Intelligence

The NBR is equipped with an advanced Intel i960 microprocessor to provide a scalable RISC-based architecture.

Hardware Bridging Logic

The NBR uses hardware packet filter/forward logic to increase bridging performance.

Connectivity

The NBR-220 and the NBR-420 have two Ethernet ports (A and B channels) and the NBR-620 has four Ethernet ports (A, B, C, and D channels). These ports provide external connections through Ethernet Port Interface Modules (EPIMs) located on the NBR faceplate.
