Chapter 5 NPE-G1 Overview

NPE-G1 Description and Overview

–Three Gigabit Ethernet interfaces (six ports: three GBIC [optical] and three RJ-45s [copper]). Any three ports are available at the same time and are linked directly to the BCM1250 system; therefore the interfaces are not charged bandwidth points.

–CompactFlash Disk for storing the default Cisco IOS software image. The CompactFlash Disk slot can be used whether or not an I/O controller is in the router.

–Auxiliary port with full data terminal equipment (DTE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its auxiliary port is the default port.)

–Console port with full data communications equipment (DCE) functionality. (Functional when an I/O controller is not present. If an I/O controller is present, its console port is the default port.)

–Boot ROM for storing sufficient code for booting the Cisco IOS software.

–Flash memory for storing the boot helper (boot loader) image. (The boot helper image comes installed on the NPE-G1.) If an I/O controller is present, its flash memory is no longer available.

–NVRAM for storing the system configuration and environmental monitoring logs. NVRAM uses lithium batteries to maintain its contents when disconnected from power. If an I/O controller is present, its NVRAM memory is no longer available.

–Upgradable memory modules

Note An I/O controller can be used with the NPE-G1, but an I/O controller is not necessary for system functionality. Installing an I/O controller in a chassis with the NPE-G1 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the NPE-G1. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G1 and I/O controller when both cards are installed.

The three interfaces on the NPE-G1 consist of three Gigabit Interface Converter (GBIC) ports and three 10/100/1000 Fast Ethernet/Gigabit Ethernet ports. The rules for using these ports are:
