Physical Description
The Cisco 7200 VXR routers are the newest, multiservice members of the Cisco 7200 series routers. The
Cisco 7200 VXR routers include the Cisco 7204VXR (4-slot router) and the Cisco 7206VXR (6-slot
router). The Cisco 7200 VXR routers are designed to support gigabit capabilities and to improve data,
voice, and video integration in both service provider and enterprise environments.
The Cisco 7200 VXR routers incorporate an integrated Multiservice Interchange (MIX) capability to
support future voice applications. MIX interconnections on the midplane provide the ability to switch
DS-0 time slots between multichannel T1 or E1 interfaces, much like a digital cross-connect or an
add-drop multiplexer. This feature enables the Cisco 7200 VXR routers to switch DS-0 voice channels
on a T1 or E1 interface from one voice processing port adapter to another voice processing port adapter.
It also enables DS-0s to be switched through the Cisco 7200 VXR routers without any processing, a
requirement in certain voice configurations.

Chapter 1 Cisco 7200 VXR Product Overview
Physical Description
The Cisco 7200 VXR routers support the high-speed network processing engine, NPE-G2, and all other
available network processing engines. The NPE-G2 provides high-speed performance with the Motorola
Freescale 7448 1.67-GHz processor and supports three Gigabit Ethernet interfaces with no additional
bandwidth requirements. The NPE-G2 also provides a dedicated Fast Ethernet Management port and two
USB ports for data storage and security tokens.
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-G2, 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 Hardware
Configuration Guidelines publication.
The Cisco 7200 VXR routers accommodate a variety of network interface port adapters and I/O
controllers. Because both the NPE-G1 and NPE-G2 contain I/O controller functionality, they can be used
without an I/O controller installed. The NPE-G2 and NPE-G1 provide a third PCI bus, which enables
the Port Adapter Jacket Card to be installed in the I/O controller slot to allow usage of an additional
high-bandwidth-usage port adapter.
A Cisco 7200 VXR router equipped with an 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 VXR routers and
are described in the “Field-Replaceable Units” section on page 1-10. The network processing engines
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.
Note The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in
the Port Adapter Jacket Card does support OIR.
•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.

Cisco 7204VXR Overview
Figure 1-2 Cisco 7204VXR Router—Rear View
The NPE-G2 and NPE-G1 have external connectors and status LEDs for the three Gigabit Ethernet
interfaces as well as console and auxiliary ports. The network processing engines NPE-100 through
NPE-400 or network services engine (NSE-1) have no external connectors or LEDs. There is a handle
for removing and installing the network processing engine or network services engine and two captive
installation screws for securing it to the chassis.
The Port Adapter Jacket Card is supported in the I/O controller slot.
The Cisco 7204VXR router comes equipped with one 280W AC-input power supply. (A 280W DC-input
power supply option is available.) In Figure 1-2, a Cisco 7204VXR router is configured with a single
AC-input power supply. (A power supply filler plate is installed over the second power supply bay.) A
fully configured Cisco 7204VXR 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.
Note The Cisco 7204VXR does not support a mixture of AC- and DC-input power.
The power supply has the router’s main power switch and either an AC-input power receptacle or a
hardwired DC-input power cable (depending on the type of installed power supply).
Caution Do not mix power supplies in the Cisco 7204VXR. In dual power supply router configurations, both
power supplies must be of the same type (two AC-input power supplies or two DC-input power supplies).

Three internal fans draw cooling air into the chassis and across internal components to maintain an
acceptable operating temperature. (See Figure 1-2.) The three fans are enclosed in a tray that is located
inside the chassis.
Caution To ensure the proper flow of cooling air across the internal components, make sure blank port adapters
are installed in unoccupied port adapter slots, and power supply filler plates are installed in unoccupied
power supply bays.
The I/O controller, port adapters, Port Adapter Jacket Card, power supplies, and network processing
engine or network services engine slide into their respective chassis slots and connect directly to the
routers midplane; there are no internal cables to connect. The midplane distributes power from the power
supplies to the I/O controller, port adapters, Port Adapter Jacket Card, fan tray, and network processing
engine or network services engine.
The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to
packet memory on the network processing engine or network services engine, arbitrates traffic across
the PCI buses, and generates the clock signals for the port adapters on each PCI bus.
Note The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in the Port
Adapter Jacket Card does support OIR.
The Cisco 7204VXR operates as either a tabletop or a rack-mounted unit. A rack-mount kit is standard
equipment included with all Cisco 7200 VXR routers when they are shipped from the factory. The kit
provides the hardware needed to mount the router in a standard 19-inch equipment rack or a 2-post rack.
Steps for installing the Cisco 7204VXR router in an equipment rack are the same for all Cisco 7200
VXR routers and are explained in Chapter 3, “Installing a Cisco 7200 VXR Router.” If you are not
rack-mounting your Cisco 7204VXR, place it on a sturdy tabletop or platform.
A fully configured Cisco 7204VXR, with two installed power supplies and all chassis slots filled, weighs
approximately 50 pounds (22.7 kilograms [kg]). For clearance requirements and rack-mount installation
considerations, see Chapter 2, “Preparing for Installation,” the “Site Requirement Guidelines” section
on page 2-3.
Cisco 7206VXR Overview
The Cisco 7206VXR supports multiprotocol, multimedia routing and bridging with a wide variety of
protocols and port adapter combinations available for Cisco 7200 series routers. In addition, the
Cisco 7206VXR midplane provides increased support for multiple high-bandwidth port adapters.
Note The Cisco 7206VXR is also available as a router shelf in a Cisco AS5800 Universal Access Server. If
your Cisco 7206VXR is installed as a router shelf, use this publication in conjunction with the
Cisco AS5800 Universal Access Server publications that shipped with the access server.
The Cisco 7206VXR has six slots (slot 1 through slot 6) for port adapters, one slot for an input/output
(I/O) controller, and one slot for a network processing engine or network services engine. You can place

Note Replacement instructions for removing and replacing FRUs are contained in separate online documents.
For example, if you need to replace an AC power supply in your Cisco 7200 VXR router, refer to the
280-Watt AC-Input Power Supply Replacement Instructions publication.Replacement instructions are
available on the Documentation DVD and on Cisco.com.
Network Processing Engine or Network Services Engine
The network processing engine or network services engine maintains and executes the system
management functions for Cisco 7200 VXR routers. Also, the network processing engine or network
services engine shares the system memory and environmental monitoring functions with the I/O
controller.
Because the NPE-G1 and NPE-G2 contain I/O functionality, the Cisco 7200 VXR routers can operate
with no I/O controller with an NPE-G1 or NPE-G2 installed. With both an I/O controller and the
NPE-G1 or NPE-G2 installed, the NPE-G1 or NPE-G2 enhances the I/O controller functionality.
Cisco 7200 VXR routers support nine versions of the network processing engine: NPE-G2, NPE-G1,
NPE-400, NPE-300, NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100. These network processing
engines have the same functionality; however, their performance differs because of the microprocessor
type and the type of memory for packet data (SRAM and DRAM, or SDRAM) that each network
processing engine provides.
Cisco 7200 VXR routers also support the NSE-1, which consists of two modular boards: the processor
engine board and the network controller board. The NSE-1 Parallel eXpress Forwarding (PXF) processor
works with the Route Processor to provide accelerated packet switching, as well as accelerated IP
Layer 3 feature processing.
Note Detailed instructions for removing and replacing the network processing engines or network services
engine are contained in the online Network Processing Engine and Network Services Engine Installation
and Configuration publication. It is available on the Documentation DVD and on Cisco.com.
The network processing engines and network services engine consist of the following components:
•Reduced instruction set computing (RISC) microprocessor
– The NPE-G2 uses a Motorola Freescale 7448 microprocessor that operates at an internal clock
speed of 1.67 GHz.
– The NPE-G1 uses aBCM 1250 microprocessor that operates at an internal clock speed of 700 MHz.
– The NSE-1 uses an RM7000 microprocessor that operates at an internal clock speed of
262 MHz.
– The NPE-400 uses an RM7000 microprocessor that operates at an internal clock speed of
350 MHz.
– The NPE-300 uses an RM7000 microprocessor that operates at an internal clock speed of
262 MHz.
– The NPE-225 has an RM5271 microprocessor that operates at an internal clock speed of
262 MHz.

1-12
Cisco 7200 VXR Installation and Configuration Guide OL-5013-08
Chapter 1 Cisco 7200 VXR Product Overview
Field-Replaceable Units
– The NPE-200 has an R5000 microprocessor that operates at an internal clock speed of
200 MHz.
– The NPE-175 has an RM5270 microprocessor that operates at an internal clock speed of
200 MHz.
– The NPE-100 and NPE-150 have an R4700 microprocessor that operates at an internal clock
speed of 150 MHz.
•System controller
– The NPE-G2 has one system controller that provides processor access to the three midplane PCI
buses, and also holds the system memory and environmental monitoring functions.
– The NPE-G1 BCM 1250 maintains and executes the system management functions for the
Cisco 7200 VXR routers and also holds the system memory and environmental monitoring
functions.
– The NSE-1 has one system controller that provides processor access to the midplane and single
I/O controller PCI buses. The system controller also allows port adapters on either of the two
midplane PCI buses to access SDRAM.
– The NPE-400 has one system controller that provides system access.
– The NPE-300 has two system controllers that provide processor access to the two midplane and
single I/O controller PCI buses. The system controller also allows port adapters on either of the
two midplane PCI buses to access SDRAM.
– The NPE-175 and NPE-225 have one system controller that provides processor access to the
two midplane and single I/O controller PCI buses. The system controller also allows the
port adapters on either of the two midplane PCI buses to access SDRAM.
– The NPE-100, NPE-150, and NPE-200 have a system controller that uses direct memory access
(DMA) to transfer data between DRAM and packet SRAM on the network processing engine.
•Upgradable memory modules
– The NPE-G2 uses SDRAM for storing all packets received or sent from network interfaces, The
SDRAM also stores routing tables and network accounting applications. A single SDRAM
memory array in the system allows concurrent access by port adapters and the processor.
– The NPE-G1 uses SDRAM for storing all packets received or sent from network interfaces. The
SDRAM also stores routing tables and network accounting applications. Two independent
SDRAM memory arrays in the system allow concurrent access by port adapters and the
processor.
– The NSE-1 uses SDRAM for providing code, data, and packet storage.
– 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-300 uses SDRAM for storing all packets received or sent from network interfaces. The
SDRAM also stores routing tables and network accounting applications. Two independent
SDRAM memory arrays in the system allow concurrent access by port adapters and the
processor.
– The NPE-175 and NPE-225 use SDRAM for providing code, data, and packet storage.

– The NPE-100, NPE-150, and NPE-200 use DRAM for storing routing tables, network
accounting applications, packets of information in preparation for process switching, and
packet buffering for SRAM overflow (except in the NPE-100, which contains no packet
SRAM). The standard configuration is 32 MB, with up to 128 MB available through single
in-line memory module (SIMM) upgrades.
•Packet SRAM for storing packets of information in preparation for fast switching
The NPE-150 has 1 MB of SRAM and the NPE-200 has 4 MB of SRAM. No other network
processing engine or network services engine has SRAM.
•Cache memory
– The NPE-G2 has two levels of cache: a primary and a secondary cache that are internal to the
microprocessor, with the secondary unified cache for data and instruction.
– The NPE-G1 has two levels of cache: a primary and a secondary cache that are internal to the
microprocessor, with the secondary unified cache for data and instruction.
– The NSE-1 has three levels of cache: a primary and a secondary unified cache that are internal
to the microprocessor, and a tertiary 2-MB external cache.
– 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 NPE-300 has three levels of cache: a primary and a secondary cache that are internal to the
microprocessor, and a tertiary 2-MB external cache that provides additional high-speed storage
for data and instructions.
– The NPE-225 has two levels of cache: a primary cache that is internal to the processor and a
secondary 2-MB external cache that provides additional high-speed storage for data and
instructions.
– The NPE-200 has unified cache SRAM that functions as the secondary cache for the
microprocessor. (The primary cache is within the microprocessor.)
– The NPE-175 has two levels of cache: a primary cache that is internal to the processor and a
secondary 2-MB external cache that provides additional high-speed storage for data and
instructions.
– The NPE-150 has unified cache SRAM that functions as the secondary cache for the
microprocessor. (The primary cache is within the microprocessor.)
– The NPE-100 has unified cache SRAM that functions as the secondary cache for the
microprocessor. (The primary cache is within the microprocessor.)
•Two environmental sensors for monitoring the cooling air as it leaves the chassis
•Boot ROM for storing sufficient code for booting the Cisco IOS software; the NPE-G2, NPE-G1,
NSE-1, NPE-400, NPE-300, NPE-225, NPE-200, and NPE-175 have boot ROM.
