●
The Cisco NPE-G2 supports three types of Small Form Factor Pluggable optics (SFP)
interfaces—Short wave (SX), long wave/long haul (LX/LH), and extended wavelength (ZX)
for varying fiber length requirements.
●
Console and auxiliary ports—The Cisco NPE-G2 has a console port and an auxiliary port,
and it handles the other functions of the I/O controller, the need for an I/O controller is
eliminated. However, an I/O controller can still be used, if desired. If an I/O controller is
detected in the I/O controller slot, the I/O controller function defaults to the I/O controller
(with the exception of NVRAM and bootflash memory). The console and auxiliary ports of
the Cisco NPE-G2 are then disabled.
●
Management 10/100 Mbps Ethernet port—This Ethernet port is strictly dedicated for
management purposes.

Memory
●
SDRAM—The Cisco NPE-G2 ships with the highest default memory available on all of the
Network Processing Engines (NPEs) on the Cisco 7200 VXR series available, 1-GB
SDRAM. There is only one memory slot. The type of memory on the Cisco NPE-G2 is
double data-rate (DDR) memory, which provides high-performance memory access rates.
Note: The NPE-G1 SDRAM memory module is not compatible with the NPE-G2 SDRAM
memory module.
●
Compact Flash memory—The 256-MB Compact Flash memory used on the Cisco NPE-
G2 is the same Compact Flash memory used with the Cisco NPE-G1, Cisco 7401, and
Cisco 7300 Series routers.
●
2-MB NVRAM
●
1-MB Layer 2 cache
●
64-MB bootflash—The 64-MB internal flash memory is large enough to hold multiple boot
helper images and logging files.
●
USB ports—The USB Flash feature provides an optional secondary storage capability.
Images, configurations, or other files can be copied to or from the Cisco USB Flash
memory with the same reliability as storing and retrieving files using the Compact Flash
card. Cisco USB Flash memory is available in 64- and 128-MB sizes.
