Cisco 7200 VXR Installation and Configuration Guide 78-5469-03
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.
The Cisco 7200 VXR routers support a high-speed network services engine
(NSE) as well as the high-speed network processing engine, NPE-400, and all
other available network processing engines. The NSE-1 is a combination of a
high-performance RISC processor and high-performance PXF processor. The
PXF processor works with the routing 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 NSE-1 and NPE-400 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 an I/O controller. 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 series routers and are described in the “Field-Replaceable Units”
section on page 1-13. The network processing engines and network services
engine are router model specific.

Chapter 1 Cisco 7200 VXR Product Overview Physical Description
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.

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).
Adjacent to the power supply bays are two chassis grounding receptacles that
provide a chassis ground connection for ESD equipment or a two-hole grounding
lug. (See Figure 1-2.)
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, 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, 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.
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 telco 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 the chapter “Installing a Cisco 7200
VXR Router.” If you are not rack-mounting your Cisco 7204VXR, place it on a
sturdy tabletop or platform.

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 series VXR routers.
Also, the network processing engine or network services engine shares the system
memory and environmental monitoring functions with the I/O controller.
Cisco 7200 VXR routers support six versions of the network processing engine:
NPE-100, NPE-150, NPE-175, NPE-200, NPE-225, NPE-300 and NPE-400.
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.
Note The NPE-100, although still supported, is no longer an
orderable product as of May 2000.
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 routing 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
Network Processing Engine and Network Services Engine
Installation and Configuration publication. This document
accompanies every network processing engine or network services
engine that is shipped from the factory as a FRU. It is also available
on the Documentation CD-ROM and on Cisco Connection Online
(CCO).
The network processing engines and network services engine consist of the
following components:
•Reduced instruction set computing (RISC) microprocessor
