Chapter 6 NPE-G2 Overview

NPE-G2 Description and Overview

Bandwidth Requirements

The Gigabit Ethernet ports on the NPE-G2 do not use bandwidth points, nor does the Fast Ethernet management port. When used with any I/O controller, the Ethernet ports, Fast Ethernet ports, or Gigabit Ethernet ports on the I/O controller also do not use bandwidth points.

Components

The NPE-G2 consists of the following components:

Motorola Freescale 7448 processor

Microprocessor operates at an internal clock speed of 1.67 GHz.

Hardware logic to interconnect the processor, double data rate synchronous dynamic random-access memory (DDR-SDRAM), lightning data transport (LDT) bus, the generic PCI bus, and three direct-interface Gigabit Ethernet interfaces.
