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
Figure 6-1 illustrates the NPE-G2 and its major components.
Figure 6-1 NPE-G2
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.
