Chapter 5 NPE-G1 Overview
NPE-G1 Description and Overview
• Only one port per interface can be used at any one time. For example, for interface
Gigabit
Ethernet 0/1, either the RJ-45 port can be used or the GBIC port, but not both.
• A total of three ports on any of the three interfaces (0/1, 0/2, or 0/3) can be used at any one time; for
example, 0/1 GBIC, 0/2 GBIC, and 0/3 RJ-45.
• The port numbering for the interfaces on the NPE-G1 start with 0/1 and not with 0/0, as is typical
for other interface cards. This is to avoid conflicts with the Ethernet and FastEthernet ports on an
I/O controller, if it is also installed.
Figure 5-3 NPE-G1 LEDs
The NPE-G1 faceplate contains LEDs that indicate system and port status. The RJ-45 and GBIC ports
share the same LINK LED because only one of these ports per interface (0/1, 0/2, or 0/3) can be used at
any one time. The EN (Enable) LED is on if the RJ-45 port is in use.
The POWER ON LED is on whether or not an I/O controller is present in the router. The CompactFlash
Disk slot can be used whether or not an I/O controller is present in the router. The SLOT ACTIVE LED
is on only when the CompactFlash Disk slot is in use.
LEDs are either on or off. The LED state (on or off), not the color, determines the status of the
connection.
CompactFlash Disk
The NPE-G1 has one CompactFlash Disk slot that uses CompactFlash Disks. The device in this slot is
always addressed as disk2: when using Cisco
IOS CLI commands.
