Physical Description
high-performance RISC processor and a high-performance PXF processor. The PXF processor works
with the Route Processor to provide accelerated packet switching, as well as accelerated IP Layer 3
feature processing.
The Cisco 7200 VXR routers also support high-speed network processing engines (NPEs) to provide
increased routing and process switching performance.
The Cisco 7200 VXR routers with the NPE-G1, NPE-400, and NSE-1 installed support both 25-MHz
and 50-MHz port adapter operation.
Note For port adapter configuration information, refer to the Cisco 7200 Series Port Adapter Configuration
Guidelines publication.
The Cisco 7200 VXR routers accommodate a variety of network interface port adapters and I/O
controllers. A Cisco 7200 VXR router equipped with an NPE-G1, NSE-1, or 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. The Cisco 7200 VXR routers also contain bays for up to two AC-input or
DC-input power supplies.
The port adapters, I/O controller, and power supplies are the same for all Cisco 7200 series routers and
are described in the
and network services engine are router model specific.
The Cisco 7200 VXR routers support the following features:

Online insertion and removal (OIR)—Allows you to 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's power requirements without interrupting normal operation of the
router.
Environmental monitoring and reporting functions—Allow you to maintain normal system
operation by resolving adverse environmental conditions prior to loss of operation.
Downloadable software—Allows you to load new images into Flash memory remotely, without
having to physically access the router, for fast, reliable upgrades.
