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.

–
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.

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.

NPE-G1 Interfaces
The three interfaces on the NPE-G1 consist of three Gigabit Interface Converter (GBIC) ports and three
