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.

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. 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.

See Table 1-1 for the Cisco 7200 VXR physical specifications and power requirements:

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.)

With the NPE-G1 or NPE-G2 installed and the Port Adapter Jacket Card installed in the I/O controller slot, an additional port adapter slot is available.


Note If you have difficulty installing a processing engine or I/O controller in the lowest slot of a Cisco 7200 VXR router that is rack-mounted, remove the port adapters, processing engine and I/O controller from the chassis and reinstall them. Install the processing engine and I/O controller in the lowest slots first, then populate the slots above them, in a bottom-to-top order.

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).

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, 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 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.)

With the NPE-G1 or NPE-G2 installed and the Port Adapter Jacket Card installed in the I/O controller slot, an additional port adapter slot is available.


Note If you have difficulty installing a processing engine or I/O controller in the lowest slot of a Cisco 7200 VXR router that is rack-mounted, remove the port adapters, processing engine and I/O controller from the chassis and reinstall them. Install the processing engine and I/O controller in the lowest slots first, then populate the slots above them, in a bottom-to-top order.

Field-Replaceable Units

The Cisco 7200 VXR routers are easy to service; many of their major components are field-replaceable units (FRUs). The following sections describe Cisco 7200 VXR router FRUs:

Network Processing Engine or Network Services Engine

Input/Output Controller

LED Descriptions

Port Adapters and Service Adapters

Port Adapter Jacket Card

Power Supplies

Chassis

CompactFlash Disks, Flash Disks, and PC Cards

Rack-Mount and Cable-Management Kit


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 a BCM 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.

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.

The network processing engines and network services engine perform the following system management functions:

Sending and receiving routing protocol updates

Managing tables, caches, and buffers

Monitoring interface and environmental status

Providing Simple Network Management Protocol (SNMP) management through the console and Telnet interface

Accounting for and switching of data traffic

Booting and reloading images

Managing port adapters (recognition and initialization during online insertion and removal)

Note The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet memory requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed configuration in the factory.

Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3 (see Figure 1-9). Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM in slot 3 can be zero.

Input/Output Controller

This section describes five different models of I/O controllers. These models are distinguished from one another by their Ethernet interface options. Table 1-22 lists the I/O controllers by product number and describes their differences.


Note For a description of the configuration commands you need to configure the different interfaces on your I/O controller, refer to the Input/Output Controller Replacement Instructions document.


Table 1-22 I/O Controller Descriptions 

Product Number
Description

C7200-I/O-GE+E

1 Gigabit Ethernet and 1 Ethernet port; equipped with a GBIC receptacle for 1000 megabits per second (Mbps) operation and an RJ-45 receptacle for 10-Mbps operation. (See Figure 1-15.)

C7200-I/O-2FE/E

2 autosensing Ethernet/Fast Ethernet ports; equipped with 2 RJ-45 receptacles for 10/100-Mbps operation. (See Figure 1-16.)

C7200-I/O-FE1

1 Fast Ethernet port; equipped with an MII receptacle and an RJ-45 receptacle for use at 100 Mbps full-duplex or half-duplex operation. Only 1 receptacle can be configured for use at a time. (See Figure 1-17 and Figure 1-18 .)

C7200-I/O

Has no Fast Ethernet port. (See Figure 1-19 and Figure 1-20.)

C7200-I/O-FE-MII2

1 Fast Ethernet port; equipped with a single MII receptacle. (See Figure 1-21.)

1 The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included.

2 The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII Fast Ethernet receptacle only. Although still supported by Cisco, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998.


You can also identify your I/O controller model from a terminal by using the show diag slot 0 command. (See the "Viewing Your System Configuration" section on page 4-20.)

The I/O controllers consist of the following components and options:

Ethernet, Fast Ethernet, or Gigabit Ethernet interface options

Dual channels for local console and auxiliary ports

The console port has full data communications equipment (DCE) functionality and the auxiliary port has full data terminal equipment (DTE) functionality.

NVRAM for storing the system configuration and environmental monitoring logs


Note NVRAM uses lithium batteries to maintain its contents when disconnected from power. Some I/O controllers use a static RAM (SRAM) component with an external lithium battery to provide the same functionality as the NVRAM.


Two PC Card (PCMCIA) slots that hold Flash Disks or PC Cards for storing the default Cisco IOS software image

Flash memory for storing the boot helper image

Boot ROM for storing sufficient code for booting the Cisco IOS software

Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis

3 The NVRAM on some I/O controllers is replaced by a 32-pin nonsocketed SRAM component that is soldered onto the card. The SRAM component is made to act like the NVRAM by the addition of some external components, one of which is a 1-inch (2.54-cm) button-type lithium battery.


LED Descriptions

All I/O controllers have LEDs, and the NPE-G1 and NPE-G2 also have interfaces that have LEDs.

The I/O controller faceplate contains LEDs that indicate system and port status; two additional LEDs indicate the status of the Flash Disk or flash memory cards installed in either PC Card slot. A CPU reset button is located next to the IO POWER OK LED or next to the auxiliary port on the I/O controller faceplate. The CPU reset button resets the entire system.

The NPE-G2 and NPE-G1 faceplate contains LEDs that indicate system and port status. The RJ-45 and GBIC or SFP ports share the same LINK LED because only one of these ports per interface (0/1, 0/2, or 0/3) can be used at any one time. The ENABLE LED is on if the RJ-45 port is in use. The POWER ON LED on the NPE-G1 or the PWR OK LED on the NPE-G2 is on when the system is powered on, whether or not an I/O controller is in the system with the NPE-G1 or NPE-G2. The SLOT ACTIVE LED is on if there is a CompactFlash Disk in the NPE-G1. The CF ACTV LED is on if there is a CompactFlash Disk in the NPE-G2.


Caution To prevent system errors and problems, use the CPU reset button only at the direction of your service representative.

Table 1-24 lists LEDs common to all models of I/O controllers and describes their functions. Table 1-25 lists LEDs on the NPE-G2. Figure 1-21 lists the LEDs on the NPE-G1.


Note LEDs are either on or off. The LED state (on or off), not the color, determines the status of connection. However, most LEDs are green when on, with the exception of the IO POWER OK LED, which is amber when in the on state. However, with the introduction of the NPE-G2, flashing LEDs are also indicative of activity.

Port Adapters and Service Adapters

The port adapters and service adapters installed in the Cisco 7200 VXR routers are of the same type as those installed on the second-generation Versatile Interface Processors (VIPs) in the Cisco 7500 series routers, in Cisco 7000 series routers with the Cisco 7000 series Route Switch Processor (RSP7000) and Cisco 7000 series Chassis Interface (RSP7000CI), in the Cisco AS5800 Universal Access Server, and in the Cisco uBR7246 universal broadband router.


Note The port adapters installed in the Cisco 7200 VXR routers support OIR. For an explanation of OIR, see the "Online Insertion and Removal" section.


All port adapters and service adapters connect to two Peripheral Component Interconnect (PCI) buses on the router midplane. The PCI buses provide a path to packet I/O memory and the system (route/switch) processor. The Fast Ethernet port on the I/O controller connects to a third PCI bus for packet routing and switching. The port or service adapters either provide such services as compression or encryption, or they provide network interfaces to connect the router to external networks.


Note Detailed instructions for removing, replacing, and configuring the port adapter types supported on the Cisco 7200 VXR routers are contained in the configuration note for the port adapter. For example, if you plan to replace a 4-port Ethernet port adapter in your Cisco 7200 VXR router, refer to the configuration note PA-4E Ethernet 10BaseT Port Adapter Installation and Configuration. The configuration note is available on the Documentation DVD and on Cisco.com.



Caution To ensure adequate airflow across the router's port adapters, a port adapter or a blank port adapter must be installed in each port adapter slot.

The Port Adapter Jacket Card, see Figure 1-27, is used in a Cisco 7200 VXR router only with an NPE-G1 or NPE-G2 installed and with no I/O controller. The NPE-G1 has I/O controller functionality, so no I/O controller is needed. The Port Adapter Jacket Card installs in the I/O controller slot, and provides for an additional port adapter slot. The Port Adapter Jacket Card works from a third PCI bus, which provides additional bandwidth and virtually unlimited bandwidth points to the single port adapter slot. For more information, see the Port Adapter Jacket Card Installation Guide.

Power Supplies

The Cisco 7200 VXR routers come equipped with one 280W AC-input power supply. (A 280W DC-input power supply is available as an option.) You must order the second power supply separately. A second power supply, although not required, allows load sharing and increased system availability.


Note The Cisco 7200 VXR power supplies are the same as in all Cisco 7200 series routers.



Caution The DC return connection to this system is to remain isolated from the system frame and chassis (DC-I).


Caution Do not mix power supplies in Cisco 7200 VXR routers. In dual power supply configurations, both power supplies must be of the same type (two AC-input power supplies or two DC-input power supplies).


Note Detailed instructions for handling and replacing the Cisco 7200 series power supplies are contained in the configuration notes 280-Watt AC-Input Power Supply Replacement Instructions and 280-Watt DC-Input Power Supply Replacement Instructions. These configuration notes are available on the Documentation DVD and on Cisco.com.


A handle on the AC and DC power supplies provides a grip point for removing and replacing the power supply. (Figure 1-28 shows the faceplate of the AC-input power supply. Figure 1-29 shows the faceplate of the DC-input power supply.) Two captive installation screws secure the power supply to the chassis and seat the power supply in the router midplane. A power OK LED indicates that the power supply is delivering +5 VDC to the router midplane.

The DC-input power supply has DC-input power leads that are hardwired to a DC-input terminal block. A cable tie is shipped with each DC-input power supply to secure the leads to the power supply faceplate and provide strain relief for the leads.


Caution To ensure adequate airflow across the router power supplies, a power supply or a power supply filler plate must be installed in each power supply bay. Figure 1-4 shows a Cisco 7206VXR with an installed power supply filler plate.

Table 1-1 lists the AC-input and DC-input power supply system power specifications, including input voltage and operating current ratings.


Note Each AC-input power supply operating at 120 VAC requires a minimum of 5A service. We recommend powering the Cisco 7206VXR from a 15A receptacle at the power source.



Note Each DC-input power supply operating at -24 VDC in North America requires a minimum of 19A service. Each DC-input power supply operating at -48 VDC in North America requires a minimum of 13A service. Each DC-input power supply operating at -60 VDC in the European Community requires a minimum of 8A service.

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 20A minimum 60 VDC, is used on all current-carrying conductors. Site wiring and circuit breakers need to be sized to accommodate the maximum values for safety reasons.


The power OK LED goes off and the power supply shuts itself down when the internal DC voltages exceed allowable tolerances or the internal temperature of the power supply exceeds allowable tolerances. The power supply remains in a shutdown state until it is disconnected and reconnected to the source power, and then restarted with the power switch. The power switch turns the power supply on and starts the system. For a description of power supply shutdown conditions and thresholds, see the "Environmental Monitoring and Reporting Functions" section.

Chassis

The Cisco 7200 VXR chassis, shown in Figure 1-30, has four or six slots for the port adapters (depending on your chassis model), one slot for the I/O controller, and one bay for the subchassis. The subchassis assembly contains the midplane, the fan tray, two power supply bays, and one slot for the network processing engine. The replacement chassis includes the subchassis assembly and one power supply.


Note To replace the chassis, you must remove and replace all the port adapters, the I/O controller, and the network processing engine or network services engine; therefore, when replacing the chassis, refer to the configuration notes that explain how to remove and replace these units. The configuration notes are available on the Documentation DVD and on Cisco.com.


Figure 1-30 Cisco 7200 VXR Chassis—7206VXR Shown

CompactFlash Disks, Flash Disks, and PC Cards

The Cisco 7206VXR supports up to two installed Flash Disks or two PC Cards, also called flash memory cards. The NPE-G1 supports one CompactFlash Disk, as does the NPE-G2.


Note To avoid potential problems when you install spare Flash Disks or PC Cards in your Cisco 7206VXR, we recommend that you reformat all your Flash Disks or PC Cards on a Cisco 7206VXR that is running the Cisco IOS release recommended for your system (see Table 1-31, Table 1-32, and Table 1-33) during your regularly scheduled service times. The online document Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller explains how to reformat a PC Card.


With Flash memory (Flash Disks, PC Cards, and the Flash SIMM on the I/O controller, or the CompactFlash Disk on the NPE-G1) you can remotely load and store multiple system and boot helper images. You can download a new image over the network, and then add the new image to Flash memory or replace existing files. You can also transfer images between Flash Disks or PC Cards and the onboard Flash memory SIMM. You can then boot the router either manually or automatically from any of the stored images. Flash memory can also function as a TFTP server to allow other routers to boot remotely from stored images or copy them into their own flash memory.


Note For procedures that explain the use of the Flash Disk or CompactFlash Disk, refer to the online Using the Flash Disk document.

For procedures that explain how to replace the main, Flash, and ROM monitor memory, refer to the Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller document. This document is available on the Documentation DVD and on Cisco.com.


For NPE-G2 and NPE-G1 pre-installation information, which requires copying the running configuration from the I/O controller to a Flash Disk or TFTP server before inserting the NPE-G1 into the Cisco 7200 VXR router, see the Network Processing Engine and Network Services Engine Installation and Configuration document at http://www.cisco.com/en/US/products/hw/routers/ps341/products_installation_guide_book09186a0080551c34.html.

Rack-Mount and Cable-Management Kit

The rack-mount and cable-management kit for the Cisco 7200 VXR routers consists of rack-mount and cable-management brackets that are designed for mounting your router in 19-inch, four-post or two-post equipment racks and for relieving strain on port adapter interface cables that are installed on port adapters in the router. The kit is shipped with each Cisco 7200 VXR router and is also available as a single FRU.

For detailed instructions about how to install the rack-mount and cable-management brackets on your Cisco 7200 VXR router, see Chapter 3, "Installing a Cisco 7200 VXR Router," the "Rack-Mounting a Cisco 7200 VXR Router" section on page 3-2 and the "General Tabletop or Workbench Installation" section on page 3-14.

Functional Overview

This section provides a functional overview of the Cisco 7200 VXR routers. It describes the numbering and addressing scheme of the port adapters for the router, the environmental monitoring and reporting functions, and online insertion and removal (OIR). These descriptions help you become familiar with the capabilities of the Cisco 7200 VXR routers.

Chassis Slot and Logical Interface Numbering

In the Cisco 7200 VXR routers, the port-adapter-slot-number is the chassis slot in which a port adapter is installed, whereas the logical-interface-number is the physical location of the interface port on a port adapter.

Port adapter slots in the Cisco 7200 VXR routers are numbered from left to right— slot 1 through slot 4 in the Cisco 7204VXR (see Figure 1-31) and slot 1 through slot 6 in the Cisco 7206VXR (see Figure 1-32). Port adapter slot 0 is always reserved for the Fast Ethernet port on the I/O controller—if present.

The Media Access Control (MAC) address or hardware address is a standardized data link layer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The Cisco 7200 VXR routers use a specific method to assign and control the MAC addresses of its port adapters. For a description of the MAC address, see the "MAC Address" section.

Port adapter slots maintain the same slot number regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the port adapter slot number changes to reflect the new slot number.

You can identify port adapter slots by using software commands. To display information about all port adapter slots, use the show interfaces command. To display information about a specific port adapter slot, use the show interfaces command with the port adapter type and slot number in the format show interfaces port-adapter-type slot-number/port-number. If you abbreviate the command (sh int) and do not specify port adapter type and slot number (or arguments), the system interprets the command as show interfaces and displays the status of all port adapters and ports.

To identify port adapter slots and the Port Adapter Jacket Card and to obtain information about the port adapters, use the show diag command.

The following example shows how the show interfaces command, used without arguments, displays status information (including the physical port adapter number) for each port adapter in a Cisco 7206VXR.

In the following example, most of the status information for each interface is omitted.

MAC Address

All LAN interfaces (ports) require unique MAC addresses, also known as hardware addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the OIR feature requires a different method. (For a description of OIR, see the "Online Insertion and Removal" section.)

Using OIR, you can remove a port adapter and replace it with another identically configured one. If the new port adapter matches the port adapter you removed, the system immediately brings it online. In order to enable OIR, an address allocator with unique MAC addresses is stored in an EPROM on the router midplane. Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot. The MAC addresses are assigned to the slots in sequence. The first address is assigned to slot 0, and the last address is assigned to slot 4 in the Cisco 7204VXR or to slot 6 in the Cisco 7206VXR. Using this address scheme, you can remove port adapters and insert them into other routers without causing the MAC addresses to move around the network or be assigned to multiple devices.

Note that if the MAC addresses were stored on each port adapter, OIR would not function because you could never replace one port adapter with an identical one; the MAC addresses would always be different. Also, each time a port adapter was replaced, other devices on the network would have to update their data structures with the new address. If the other devices did not update quickly enough, the same MAC address could appear in more than one device at the same time.


Note Storing the MAC addresses for every slot in one central location means the addresses stay with the memory device on which they are stored.


Online Insertion and Removal

All port adapters and service adapters in the Cisco 7200 VXR routers support online insertion and removal (OIR). However, it is wise to shut down the interface before removing a port adapter that has active traffic moving through it. Removing a port adapter while traffic is flowing through the ports can cause system disruption. Once the port adapter is inserted, the ports can be brought back up.


Note The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in the Port Adapter Jacket Card does support OIR.



Note As you disengage the port adapter from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the port adapter.


OIR allows you to install and replace port adapters and service adapters while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter or service adapter in a Cisco 7200 VXR router, refer to the online configuration note for each port adapter or service adapter.


Caution The network processing engine or network services engine and the I/O controller are required system components that cannot be removed if the router is operating. Removing the network processing engine or network services engine or the I/O controller while the router is operating causes the router to shut down or crash and might damage or destroy memory files.

Each port adapter or service adapter has a bus connector that connects it to the router midplane. Each midplane connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter or service adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter or service adapter is being removed or inserted into the midplane. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface. For example, when you insert a port adapter or service adapter, the longest pins make contact with the port adapter or service adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter or service adapter in a Cisco 7200 VXR router, the midplane pins send signals to notify the system, which then performs as follows:

1. Rapidly scans the midplane for configuration changes.

2. Initializes all newly inserted port adapters or service adapters, noting any removed interfaces and placing them in the administratively shutdown state.

3. Brings all previously configured interfaces on the port adapter back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if they were present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the original port adapter. (A service adapter has no configurable ports.)

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions are controlled by the network processing engine or network services engine and allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation. The environmental monitoring functions constantly monitor the internal chassis air temperature and DC supply voltages and currents. Each power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. If conditions reach shutdown, the system shuts down to avoid equipment damage from excessive heat. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.

Environmental Monitoring

The environmental monitoring functions use four sensors, two on the network processing engine or network services engine and two on the I/O controller, to monitor the temperature of the cooling air as it moves through the chassis.

If the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system. The system stores the present parameter measurements for both temperature and DC voltage in NVRAM so you can retrieve them later as a report of the last shutdown parameters.

In addition, the power supplies monitor internal power supply temperatures and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If an internal power supply temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the system:

Normal—All monitored parameters are within normal tolerances.

Warning—The system has exceeded a specified threshold. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to operate; however, the system is approaching shutdown. Immediate operator action is required.

Shutdown—The processor has detected a temperature condition that could result in physical damage to system components and has disabled DC power to all internal components. This condition requires immediate operator action. All DC power remains disabled until you toggle the power switch. Before any shutdown, the system logs the status of monitored parameters in NVRAM so you can retrieve it later to help determine the cause of the problem.

Power supply shutdown—The power supply detected an internal out-of-tolerance overvoltage, overcurrent, or temperature condition and shut itself down. All DC power remains disabled until you toggle the power switch.

Table 1-34 lists the typical temperature thresholds for the NPE-G2. Table 1-35 lists the typical temperature thresholds for the NPE-G1. Table 1-36 lists the typical temperature thresholds for earlier network processing engines or network services engines, Table 1-37 lists the DC power thresholds for the normal, warning, and critical (power supply-monitored) levels for most Cisco IOS releases, and Table 1-38 lists the DC power thresholds for the normal and critical (power supply-monitored) levels for Cisco IOS Release 12.0(23) and later releases of Cisco IOS Release 12.0.

Note A low warning or high warning message does not mean that the router is at risk of malfunctioning or being damaged.


The low warning and high warning ranges in Table 1-34 and Table 1-35 are informational. If a low warning or high warning message appears, the warning message does not signify that an error or hazard is occurring. A high warning message sometimes appears in a lightly loaded chassis, especially if the router is running without port adapters or with dual power supplies. Adding current load to the router may remove the warning; this can be achieved easily by installing one or more port adapters.

Below are sample high warning messages from chassis with 3V and 5V power supplies:

Router(boot)#
00:00:44:%ENVM-4-ENVWARN:+3.45 V measured at +3.57

Router(boot)#
00:04:49:%ENVM-4-ENVWARN:+5.15 V measured at +5.33

Note Low critical or high critical warning messages should be addressed immediately through the normal field support procedures.

Reporting Functions

The Cisco 7200 VXR routers display warning messages on the console if chassis interface-monitored parameters exceed a desired threshold. You can also retrieve and display environmental status reports with the show environment, show environment all, show environment last, and show environment table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows.


Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.


Note Also see the NPE-G2 Support for the show environment Command document for information about changes to the output of the show environment command with the NPE-G2.


The show environment command displays reports of the current environmental system status. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within normal range:

Router# show environment 
 
All measured values are normal

If the environmental status is not normal, the system reports the worst-case status level. Following is a sample overvoltage warning:

Router# show environment 

Warning: +3.45 V measured at +3.83 V

The show environment last command retrieves and displays the NVRAM log, which shows the reason for the last system shutdown (if the shutdown was related to voltage or temperature) and the environmental status at that time. Air temperature is measured and displayed, and the DC voltage supplied by the power supply is also displayed.

Following is sample output of the show environment last command:

NPE300(boot)# show environment last
chassis inlet      previously measured at 26C/78F
  chassis outlet 1   previously measured at 28C/82F
  chassis outlet 2   previously measured at 29C/84F
  chassis outlet 3   previously measured at 33C/91F
  +3.45 V            previously measured at +3.46
  +5.15 V            previously measured at +5.23
  +12.15 V           previously measured at +12.24
  -11.95 V           previously measured at -11.81
  last shutdown reason - power supply shutdown

The show environment table command displays the temperature and voltage thresholds for each temperature sensor and for each monitored status level. These thresholds are related to those listed in Table 1-36 and Table 1-38. The display also lists the shutdown threshold for the system.

Following is sample output of the show environment  table command for a Cisco 7206VXR that has an installed NPE-300:

Fan Failures

When the system power is on, all three fans should be operational. The system continues to operate if a fan fails; however, if the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system.

If the system does shut down because the temperature exceeded the shutdown threshold, the system displays the following message on the console screen and in the environment display when the system restarts:
