Cisco Router 7206 VXR User Manual page 3

Cisco 7200 VXR routers accommodate a variety of network interface port adapters and an I/O controller.
A Cisco 7200 VXR router equipped with an NPE-400 can support up to six high-speed port adapters and
can also support higher-speed port adapter interfaces including Gigabit Ethernet and OC-12 ATM.
Cisco 7200 VXR routers also contain bays for up to two AC-input or DC-input power supplies.
Cisco 7200 VXR routers support the following features:

The 7206 VXR NPE-400 Cryptographic Module
Cisco 7206 VXR routers support multiprotocol routing and bridging with a wide variety of protocols and
port adapter combinations available for Cisco 7200 series routers. The metal casing that fully encloses
the module establishes the cryptographic boundary for the router. All the functionality discussed in this
document is provided by components within the casing. Cisco 7206 VXR routers have six slots for port
adapters, one slot for an input/output (I/O) controller, and one slot for a network processing engine or
network services engine.

Cisco 7206 VXR 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.
Online insertion and removal (OIR)—Add, replace, or remove port adapters without interrupting the
system.
Dual hot-swappable, load-sharing power supplies—Provide system power redundancy; if one power
supply or power source fails, the other power supply maintains system power without interruption.
Also, when one power supply is powered off and removed from the router, the second power supply
immediately takes over the router power requirements without interrupting normal operation of the
router.
Environmental monitoring and reporting functions—Maintain normal system operation by resolving
adverse environmental conditions prior to loss of operation.
Downloadable software—Load new images into Flash memory remotely, without having to
physically access the router.
