The NPE-400 uses an RM7000 microprocessor that operates at an internal clock speed of 350 MHz. The
NPE-400 uses SDRAM for storing all packets received or sent from network interfaces. The SDRAM
memory array in the system allows concurrent access by port adapters and the processor. The NPE-400
has three levels of cache: a primary and a secondary cache that are internal to the microprocessor, and a
tertiary 4-MB external cache that provides additional high-speed storage for data and instructions.
The Cisco 7206VXR router comes equipped with one 280W AC-input power supply. (A 280W DC-input
power supply option is available.) A power supply filler plate is installed over the second power supply
bay. A fully configured Cisco 7206VXR router operates with only one installed power supply; however,
a second, optional power supply of the same type provides hot-swappable, load-sharing, redundant
power.

Cisco 7206 VXR NPE-400 Module Interfaces

The interfaces for the router are located on the front panel Input/Output (I/O) Controller, with the
exception of the power switch and power plug. The module has two Fast Ethernet (10/100 RJ-45)
connectors for data transfers in and out. The module also has two other RJ-45 connectors for a console
terminal for local system access and an auxiliary port for remote system access or dial backup using a
modem.
