NPE-G2

Like the NPE-G1, the NPE-G2 provides the functionality of both a network processing engine and I/O controller. If used without an I/O controller, an I/O controller blank panel must be in place.

While its design provides I/O controller functionality, it can also work with any I/O controller supported in the Cisco 7200 VXR routers or Cisco uBR7200 series routers. The NPE-G2, when installed with an I/O controller, provides the bootflash and NVRAM that the Cisco IOS software uses to boot.

Note An I/O controller can be used with the NPE-G2, but an I/O controller is not necessary for system functionality. Installing an I/O controller in a chassis with the NPE-G2 activates the console and auxiliary ports on the I/O controller and automatically disables the console and auxiliary ports on the NPE-G2. However, you can still use the CompactFlash Disk slots and Ethernet ports on both the NPE-G2 and I/O controller when both cards are installed.

The NPE-G2 maintains and executes the system management functions for the Cisco 7200 VXR routers and Cisco uBR7200 series routers and also holds the system memory and environmental monitoring functions. The NPE-G2 consists of one board with multiple interfaces.

The NPE-G2 can be used with the Port Adapter Jacket Card installed in the I/O controller slot. If you are upgrading to an NPE-G2 and Port Adapter Jacket Card at the same time, see the Port Adapter Jacket Card Installation Guide for information about the order of installation of both the NPE-G2 and the Port Adapter Jacket Card.

The NPE-G2 consists of the following components:

  • Motorola Freescale 7448 processor
    • Microprocessor operates at an internal clock speed of 1.67 GHz.
    • Hardware logic to interconnect the processor, double data rate synchronous dynamic random-access memory (DDR-SDRAM), lightning data transport (LDT) bus, the generic PCI bus, and three direct-interface Gigabit Ethernet interfaces.
  • Cache memory
  • The NPE-G2 has two levels of cache: primary and secondary cache that are internal to the microprocessor with secondary unified cache for data and instruction.
  • The NPE-G2 uses DDR SDRAM for providing code, data, and packet storage.
  • Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis.
  • Full-feature I/O controller functionality
    • Three Gigabit Ethernet interfaces (six ports: three SFP [optical] and three RJ-45s [copper]). Any three ports are available at the same time and are linked directly to the processor; 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.)
    • Dedicated 10/100 Fast Ethernet Management port—Not to be used for any other purpose.
    • Two USB ports for data storage using Cisco USB flash memory modules or security eToken for VPN applications.
    • Boot ROM for storing the ROMmon images.
    • Internal flash memory for storing the boot helper (boot loader) image and the Cisco IOS image. (The boot helper image comes installed on the NPE-G2.) If an I/O controller is present, its internal 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 module
