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 (four-slot router) and the Cisco 7206VXR (six-slot router).

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.

Cisco 7204VXR Overview
The Cisco 7204VXR 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 7204VXR midplane provides
increased support for multiple high-bandwidth port adapters.
The Cisco 7204VXR has four slots (slot 1 through slot 4) 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 the port adapters in any of the
four available slots. (See Figure 1-1.)

Figure 1-2 Cisco 7204VXR Router—Rear View
The network processing engine or network services engine has 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 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).
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.

Chapter 1 Cisco 7200 VXR Product Overview Cisco 7206VXR Overview
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 2-4.
Cisco 7206VXR Overview
The Cisco 7206VXR supports multiprotocol, multimedia routing and bridging
with a wide variety of protocols and port adapter combinations available for 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 the port adapters in any of the six
available slots.
The front of the Cisco 7206VXR provides access to the I/O controller and up to
six network interface port adapters. (See Figure 1-3.)
