Chapter 6 NPE-G2 Overview
NPE-G2 Description and Overview
Summary of Important NPE-G2 Information
Caution The NPE-G2 requires that you copy and save your running configuration file to a CompactFlash Disk,
PC Card, or TFTP server before you install the NPE-G2. For instructions on copying and saving your
configuration file, see the
“Copying the Configuration File” section on page 7-4 in Chapter 7, “NPE-G1
and NPE-G2 Installation and Configuration Information.”
For general preparation for installation instructions, see Chapter 8, “Preparation for Installation.” For
installation and configuration instructions specific to the NPE-G2, see Chapter 7, “NPE-G1 and NPE-G2
Installation and Configuration Information.”
• The NPE-G2 software image and kboot image name begins with “c7200p-”, which is different from
that of previous network processing engines.
• The RJ-45 ports and SFP ports are both reported in software as GigabitEthernet 0/1, GigabitEthernet
0/2, and GigabitEthernet 0/3. Only one of the pair of interface ports can be used at a time; for
example, SFP GigabitEthernet 0/2 or RJ-45 GigabitEthernet 0/2.
• The I/O controller GE/E interface reports GigabitEthernet 0/0 and Ethernet 0/0, and the I/O
controller 2FE/E interface reports FastEthernet
0/0 and FastEthernet 0/1.
• If the RJ-45 port is in use, the EN (Enable) LED is on. If the SFP port is in use, the EN (Enable)
LED is off.
• With the NPE-G2 and an I/O controller both installed, the I/O controller functionality on the
NPE-G2 is shared with that of the I/O controller.
• When both an NPE-G2 and an I/O controller are installed, the flash memory and NVRAM of the
NPE-G2 are enabled and the flash memory
• and NVRAM on the I/O controller are no longer accessible.
• The console and auxiliary ports on the NPE-G2 are disabled by Cisco IOS when an I/O controller is
present; the console and auxiliary ports on the I/O controller are active.
• Console port messages can be routed to the auxiliary port on either the NPE-G2 or on the I/O
controller.
• The default media is the RJ-45 port. To change the media type, use the media-type command.
• Only the port selected by the media-type command is active. A cable attached to the other of the
RJ-45 and SFP module pair will be ignored. For example, if SFP port GigabitEthernet 0/2 is selected
using the media-type command, RJ-45 GigabitEthernet 0/2 is ignored, even if a cable is attached to
RJ-45
0/2.
• The NPE-G2 uses no bandwidth points, and when used with any I/O controller, the I/O controller
also uses no bandwidth points. None of the Gigabit Ethernet interfaces on the NPE-G2 use
bandwidth points.
• The CompactFlash Disk on the NPE-G2 is available at all times, with or without an I/O controller
installed. The CompactFlash Disk is always addressed as the disk2 device, to avoid conflicts with
the disk0 and disk1 devices on the I/O controller, if the I/O controller is also installed.
• USB Flash memory modules are available for data storage, with or without an I/O controller
installed.
