Cisco 7200 VXR
Product Overview
This chapter provides physical and functional overviews of the Cisco 7200 VXR routers.
Descriptionsandexamplesofsoftware commands are included when theyarenecessaryfor
replacing, installing, configuring, or maintaining the router hardware.
The following sections describe router hardware, major components, and functions of
hardware-related features:
•Cisco 7204VXR Overview on page 5
•Cisco 7206VXR Overview on page 8
•Field-Replaceable Units on page 12
•Functional Overview on page 46
Physical Description
The Cisco 7200 VXR routers are the newest, multiservice members of the Cisco 7200
seriesrouters.TheCisco 7200VXRroutersincludetheCisco 7204VXR(4-slotrouter)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 timeslots 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

Physical Description

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 also support a high-speed network processing engine
(NPE-300) to provide increased routing and process switching performance. The
Cisco 7204VXR and Cisco 7206VXR both support the NPE-300 in addition to supporting
all available network processing engines. The NPE-300 is a high-performance
RISC processor—delivering up to 300-Kpps fast switching and 20-Kpps process
switching. The Cisco 7200 VXR routers with the NPE-300 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 document.
TheCisco 7200 VXR routers accommodate a varietyofnetwork interfaceport adapters and
an I/O controller. A Cisco 7200 VXR router equipped with an NPE-300 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 network processing engines, 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 12.
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.

Cisco 7200 VXR Product Overview 1-3
Physical Description
•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,

Cisco 7204VXR Overview
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,bothpowersupplies must be of the same type (two AC-input powersupplies
or two DC-input power supplies).
Adjacent to the power supply bays are two chassis ground 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 slide into
their respective chassis slots and connect directly to the router’s 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.
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, 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.
