SFP Module Information

You may have ordered a small form-factor pluggable (SFP) module with your Cisco 7201 router. You must install the SFP module. It is shipped separately to prevent damage during shipment. After reading this section, use the installation instructions in the

page 4-2 to install the SFP modules.

For ease of installation, insert the SFP module in the router while it is powered down and before placing it in a rack.

The SFP port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE

802.3z interfaces compliant with the 1000BASEX standard. Gigabit Ethernet SFP models SFP-GE-S, SFP-GE-L, SFP-GE-Z, and SFP-GE-Fare supported in the Cisco The cabling information is the same for all optical SFP modules.

Also see the “SFP Module Specifications and Configurations” section on page A-4, and the Gigabit

Interface Converter (GBIC) Module and S mall Form-Factor Pluggable (SFP) GBIC Module Installation Information and Specifications document.

For optical connection cleaning information, see the Inspection and Cleaning Pr ocedures for Fiber-Optic

Connections document and the Compressed Air Cleaning Issues for Fiber-Optic Connections document.

USB Port Information

The Cisco 7201 provides a USB port that can be used with a USB Flash memory module as secondary storage, and can be used to store Cisco IOS images, data, and configuration files. The Cisco 720 1 USB port can also be used with the Aladdin USB eToken Pro key. This USB device can be used for the following functions:

deploy information, such as a bootstrap configuration or VPN credentials, separate from the router chassis. The Aladdin USB eToken Pro key uses smart card technology to protect a small area of memory and grants access using a personal identification number (PIN). When IP Security (IPSec) VPN credentials are stored on the Aladdin USB eToken Pro key, they are safely external to the router. When the USB eToken is inserted in a USB port, the router can pass the PIN and unlock it, retrieving the credentials and copying them into running memory. When the Aladdin USB eToken Pro key is removed, the router erases the credentials from running memory, ensuring that they cannot be retrieved from the router itself.

Note For more information about the eToken Pro key by Aladdin Knowledge Systems, see the

Aladdin website at www.aladdin.com/etoken/cisco.

Note The Cisco USB Flash memory module cannot be used to boot the router. The USB drivers

exist only in Cisco IOS software, not ROM Monitor mode (ROMmon). As a result, a Cisco IOS image must be booted to load the drivers; only then can files be copied to and from the USB Flash memory module.

Chapter 1 Overview

CompactFlash Disk Information

The Cisco 7201 router has one CompactFlash Disk slot that uses CompactFlash Disks. The device in this slot is always addressed as disk0: when using Cisco

CompactFlash Disks are smaller in size than Type 2 Flash Disks but provide the same AT Attachment (ATA) interface and equivalent functionality. This interface complies with the ANSI ATA Interface Document X3T13.1153 D Rev.

The CompactFlash Disk has controller circuitry that allows it to emulate a hard disk and automatically maps out bad blocks and performs automat ic block e rasure. The CompactFlash Disk also provides the capability to allocate noncontiguous sectors, which eliminates the need for the squeeze command (which was required with older-style linear flash memory cards to recover the space used by deleted files).

The CompactFlash Disk also supports the Cisco IOS File System feature, which provides a single interface to all of the router’s file systems, including the Flash Disks and flash memory, as well as network file systems such as File Transfer Protocol (FTP) and Trivial FTP (TFTP) servers.

Table A -4 on page A-3 lists the CompactFlash Disk options. Also see Appendix B, “Using the CompactFlash Disk.”

Electrical Equipment Guidelines

The port adapter is designed to be removed and replaced while t he system is o perating w ithout presenting an electrical hazard or damage to the system.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or inter mittent system failures. Each por t adapter consists of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the carrier helps protect the boards, use an antistatic strap whenever handling the port adapter. Handle the carriers by the handle and the carrier edges only; never touch the boards or connector pins.

Chapter 2 Installing the Cisco 7201 Router

Site Requirement Guidelines

Warning

Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information for Cisco 7200 Series Routers publication. This document provides important safety information you should know before working with the system

The environmental monitoring functionality in the Cisco 7201 router protects the system and components from potential damage from overvoltage and overtemperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site befo re installation. After installation, make sure the site maintains an ambient temperature of 32•F through 104•F (0•C through 40•C), and keep the area around the chassis as free from dust as is practical.

Planning a proper location for the Cisco 7201 router and the layout of your equipment rack or wiring closet is essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance dif ficult. F ollowing are precauti ons that can help avoid problems during installation and ongoing operation.

Chapter 2 Installing the Cisco 7201 Router

When you plan the location and layout of your equipment rack or wiring closet, you need to consider how air flows through your router. The Cisco 7201 router draws cooling air in through the intake vents on the front of the chassis and moves the air across the internal components and out the exhaust vents on the rear of the chassis.

Temperature sensors on the system board monitor the internal air temperature and send warning messages when the internal air temperature approaches a specified threshold. If the internal temperature exceeds the specified threshold, the system environmental monitor shuts down all internal power to prevent equipment damage from excessive heat. (See the

Functions” section on page 3-4 for temperature threshold information.)

Installing the Router

This section explains how to install a Cisco 7201 ro uter in a g eneral ta bletop o r workbenc h inst allat ion and in a rack, and how to attach I/O, port adapter, and power cables. This sect ion contains the following topics:

General Tabletop or Workbench Installation

The router should already be in the area where you will install it, and your installation location s hould already be determined. If not, see the and the “Site Requirement Guidelines” section on page 2-4.

When installing a Cisco 7201 router on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following:

• The router requires at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (the front

and back sides of the router).

• The router should be installed off the floor. (Dust that accumulates on the floor is drawn into the

interior of the router by the cooling fans. Ex cessiv e dust inside the router can cause ov ertemperature conditions and component failures.)

• There must be approximately 19 inches (48.26 cm) of clearance at the front and rear of the router

for installing and replacing router parts—such as the port adapter, SFP module, USB module, or CompactFlash Disk—or accessing network cables or equipment.

• A port adapter blank panel is installed if a port adapter or service adapter is not in place.

• The router will receive adequate ventilation (it is not being installed in an enclosed cabinet where

ventilation is inadequate).

“Preparing to Install the Cisco 7201 Router” section on page 2-1,

OL-11364-04

• If you plan to install the cable-management bracket, unpack and ha v e handy the cable-management

bracket and one M4 x 20-mm screw.

• An adequate chassis ground (earth) connection exists for your router chassis.

Warning

This product relies on the building’ s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 120 VAC, 20A U.S. (240 VAC, 10A international).

Statement 1005

Following are the steps for installing a Cisco 7201 router on a workbench or tabletop:

Step 1 Remove any debris and dust from the tabletop or workbench, as well as the surrounding area. Also make

sure your path between the router and its new location is unobstructed.

Step 2 On the chassis, ensure that the port adapter lever is in the locked position. Step 3 Lift the chassis by placing your hands around the chassis sides and lifting the chassis from underneath.

To prevent injury, avoid sudden twists or moves.

Step 4 Place the router on the tabletop or workbench. Step 5 Ensure that there is at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents of the router

and no exhaust air from other equipment will be drawn into the chassis. Also, ensure that there is approximately 19 inches (48.26 cm) of clearance at the front and rear of the chassis.

This completes the general tabletop or workbench installation. Go to the “Attaching a Chassis Ground

Connection” section on page 2-12 for the next step in installing the Cisco 7201 router.

Rack-Mounting a Cisco 7201 Router

The chassis mounts to two rack posts with brackets that attach to either the front or the rear sides of the chassis. The inside width between the two posts or mounting strips (left and right) must be at least 19 inches (48.26 cm).

Some equipment racks provide a power strip along the length of one of the mounting strips. Figure 2-7 shows a typical four-post eq uipment rack with a po wer strip along one of the back post s. If your rack has this feature, consider the position of the strip when planning fastener points to ensure that you will be able to pull the port adapter, SFP module, USB module, or CompactFlash Disk straight out of their respective slots.

The inlet and exhaust ports for cooling air are located on the front and rear of the chassis, respectively, so multiple routers can be stacked in a rack with little or no vertical clearance.

Before beginning the installation, determine the type of rack yo u are u sing and wh ether o r not you w ant the chassis front- or rear-mounted.

Note To use the cable-management bracket with the Cisco 7201 router rear-mounted, you must purchase a

second rack-mount kit, attach a rack-mount bracket to the left front of the chassis, and attach the cable-management bracket to it. See the

“ Attaching the Cable-Management Bracket” section on page 2-8

for cable-management bracket installation instructions.

This completes the procedure for installing the rack-mo unt brack ets and cable-management brack ets on a Cisco 7201 router for a rear rack-mount configuration. Go to the

section on page 2-9.

Installing the Chassis in the Rack

After installing the brackets on the chassis, you mount the router b y securing the rack-mount brackets to two posts or mounting strips in the rack using the four screws provided. Because the brackets support the weight of the entire chassis, be sure to use all four screws to fasten the two rack-mount brackets to the rack posts. two-post and four-post equipment racks.

We recommend that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the router and any equipment directly above and below it.

To install the chassis in the r ack, comp lete th e following steps:

Step 1 On the chassis, ensure that the port adapter lever is in the locked position, and that the CompactFlash

Disk, USB module, and any SFP modules are installed.

Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are

engaged or that the rack is otherwise st abilized .

Step 3 Position the chassis so that the front end is closest to you. Lift the chassis and move it to the rack. To

prevent injury, avoid sudden twists or moves.

Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the

chassis) meet the mounting strips or posts on both sides of the equipment rack.

Connecting Console and Auxiliary Port Cables

Note The console cable kit product number is ACS-2500ASYN.

The Cisco 7201 router has a DCE-mode console port for connecting a console terminal, and a DTE-mode auxiliary port for connecting a modem or other DCE de vice (such as a CSU/DSU or other router) to your router.

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these

ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The Cisco 7201 router uses RJ-45 ports for both the auxiliary port and the console port. For console and auxiliary port pinouts for the RJ-45 connector, see Appendix A, “Specifications.”

When using the Fast Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automati cally sens es a crossover or straight-through cable and adapts to it.

However, when the Fast Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface (C LI) comma nds, the port is forced to MDI mode.

When in a fixed-speed configuration and MDI mode:

• Use a crossover cable to connect to an MDI port

• Use a straight-through cable to connect to an MDI-X port

Connecting Native Gigabit Ethernet Cables

The Cisco 7201 router has four native Gigabit Ethernet interfaces and six physical Gi gabit Ethernet ports, four SFP ports (optical) and two RJ-45 ports (copper). The use of an RJ-45 port or SFP port on a common Gigabit Ethernet interface is mutually exclusive at any one time.

Gigabit Ethernet SFP Connection Equipment

The SFP port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. (See Figure 2-16.)

Chapter 2 Installing the Cisco 7201 Router

Warning

Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

Figure 2-16 shows the duplex LC-type connectors on your multimode or single-mode optical fiber

cables. For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX). For duple x connectors, only one cable that has both TX and RX connectors is requ ired. You can use either simplex or duplex connectors to the SFP ports on the Cisco 7201 router.

Appendix A, “Specifications, ” provides cabling specifications and conf iguration information for the SFP

modules that you install in the Gigabit Ethernet SFP ports. The following SFP modules are supported on the Cisco 7201:

• 100BASE-FX SFP—The SFP-GE-F=,100BASE-FX SFP module is a hot-swappable device that

plugs into a Gigabit Ethernet SFP port. It provides full-duplex 100-Mbps connectivity over multimode fiber (MMF) infrastructures. The 100BA SE-FX SFP operates on ordinary MMF optical link spans of up to 2 kilometers (km) in length.

• 1000BASE-LH/LX SFP module—The SFP-GE-L= (1000BASE-LH/LX SFP module) operates on

ordinary single-mode fiber-optic link spans of up to 32,808 feet (10,000 meters) in length.

• 1000BASE-SX SFP module—The SFP-GE-S= (1000BASE-SX SFP module) operates on ordinary

multimode fiber-optic link spans of up to 1804 feet (550 meters) in length.

2-18

1000BASE-ZX SFP module—The SFP-GE-Z= (1000BASE-ZX SFP module) operates on ordinar y single-mode fiber-optic link spans of up to 43 miles (70 kilometers) in length. Link spans of up to 100 km are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. The SFP module provides an optical link budget of 23 dB—the precise link span length depends on multiple factors, such as fiber quality, number of splices, and connectors.

Cisco 7201 Installation and Configuration Guide

OL-11364-04

Chapter 2 Installing the Cisco 7201 Router

When shorter distances of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 5-decibel (dB) or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP-GE-Z= at each end of the link whenever the fiber-optic cable span is less than 25 km.

• 1000 BASET SFP module—The SFP-GE-T (1000B ASET copper SFP module) provides full-duple x

Gigabit Ethernet connectivity to high-end w orkstations and between wir ing closets ov er an e xisting copper network infrastructure. The SFP-GE-T maximum cabling distance is 328 feet (100 m).

Caution If you plan to use a S FP-GE-L at d istances greater than 984.2 5 feet (300 meter s) over 50/125-micron or

62.5/125-micron multimode fiber, you must use the mode-conditioning patch cord to prevent data transmission problems.

Mode-Conditioning Patch Cord Description

A mode-conditioning patch cord can be used with the SFP-GE-L= (SFP module) to allow reliable laser transmission between the single-mode laser source on the SFP module and a multimode optical fiber cable.

When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.

A mode-conditioning patch cord is an optical fiber cable assembly that consists of a p air of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in multimode optical fiber. Figure 2-17 shows a diagram of the mode-conditioning patch cord assembly.

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASE-LX and 1000BASE-LH links.

Connecting I/O Cables

The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which i s accomplished by usin g the mode-conditioni ng patch cord. At the output of the mode-conditioning patch cord, the SFP-GE-L= is complian t with t he IEEE 802.3z standard for 1000BASE-LX.

Note W e strongly recommend cleani ng optical fiber conn ections before attaching cables to equipm ent. See the

“Cleaning the Fiber-Optic Connections” section on page 5-14 for information.

To use a mode-conditioning patch cord, follow these steps:

Step 1 If you have not already done so, and the mode-conditioning patch cord has been in use, we strongly

recommend cleaning optical fiber connections before attaching cables to equipment. See the

the Fiber-Optic Connections” section on page 5-14 for information.

Step 2 Attach a mode-conditioning patch cord to the SFP module. (See Figure 2-17.) Step 3 Attach the network ends of your mode-conditioning patch cord to the appropriate 1000BASEX

equipment in your building cable plant. Ensure that you connect the TX and RX ports on one end of the patch cord to the RX and TX ports

(respectively) on the other end. Connect TX to RX and RX to TX.

Note See Chapter 3, “Starting and Configuring the Router,” the “Configuring the Native Gigabit Ethernet

Interfaces” section on page 3-15, for information on configuring and troubleshooting the Gigabit

Ethernet interfaces.

Attaching the Gigabit Ethernet RJ-45 Cables

The RJ-45 ports support IEEE 802.u (Fast Ethernet) and 802.3ab (Gigabit Ethernet) twisted-pair interfaces compliant with 1000BASETX and 1000BASET specifications.

Note RJ-45 ports GE/00 and GE/01 are always set to MDI mode.

The RJ-45 ports support standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables with RJ-45 connectors. Cisco does not supply Category 5 UTP cables; these cables are available commercially.

See Appendix A, “Specifications,” for Gigabit Ethernet RJ-45 port spec ifications.

Intra-Building Lightning Protection

Shielded cables, which are grounded at both ends, are required to be used on the 10/100/1000 Gigabit Ethernet RJ-45 ports in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requirement for customer premises installations.

Functional Overview

Chassis Slot and Logical Interface Numbering

In the Cisco 7201 router, 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 inte rface port on a port adapter.

The port adapter slot in the Cisco 7201 router is numbered slot 1. Port adapter slot 0 is always reserved for logical port 10/100/1000.

The Media Access Control (MAC) 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 7201 router uses a specific method to assign and control the MAC addresses of its port adapters. F or a description of the MAC address, see the

“MAC Address” section on page 3-3.

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 ar guments), the system interpr ets the command as show interfaces and displays the status of all port adapters and ports.

Functional Overview

MAC Address

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the

All LAN interfaces (ports) require unique MAC addresses, also known as hardware addresses. T ypically, the MAC address of an int e rface 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 O IR, see the

“Online Insertion and Removal” section on page 3-4.)

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 immed iately brings it online. In order to enable OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the system board. Each address is reserved for a specific port and slot in the router regardless of whether or not a port adapter resides in that slot. The MAC address for the port adapter slot in the Cisco 7201 is designated slot 0. You can remove a port adapter and insert it into another router 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 w as replaced, other devices on the netw ork would ha ve 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.

memory device on which they are stored.

Functional Overview

Online Insertion and Removal

All port adapters and service adapters in the Cisco 7201 router 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.

Caution 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 do wn the system po wer , although you should not run traf fic 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 7201 router, refer to the online configuration note for each port adapter or service adapter.

Chapter 3 Starting and Configuring the Router

Each port adapter or service adapter has a bus connector that connects it to the router . The con nector 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 system. 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 7201 router , t he pins send signal s to notify the system, which then performs as follows:

1. Rapidly scans the system for co nfiguration 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 interface is put in the administrati v ely shutdown state, as if it was present (but not conf igured) at bo ot time. If a similar port adapter ty pe is reinserted into a sl ot, 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

3-4

Environmental monitoring and reporting functions 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. If conditions reach shutdown thresholds, 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.

Cisco 7201 Installation and Configuration Guide

OL-11364-04

Chapter 3 Starting and Configuring the Router

Environmental Monitoring

The environmental monitoring functions use two sensors, Sensor 1 (U12) on the underneath front edge of the system board, and Sensor 2 (U20), near the fans. If the air temperature exceeds a defi ned 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.

If an internal power supply temperature or voltage reaches a critical level, the power supply shuts do wn 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 syste m is approaching shutdown. Immediate operator action is required.

• Shutdown—The processor has detected a tem perature 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.

Functional Overview

• Power supply shutdown—The power supply detected an internal out-of-tolerance overvoltage,

overcurrent, or temperature cond ition and shut itself do wn. All DC po wer remains disabled until you toggle the power switch.

Reporting Functions

The Cisco 7201 router displays 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.

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

Chapter 3 Starting and Configuring the Router

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 +3.27 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:

Router# show environment last NPE Inlet previously measured at 28C/82F NPE Outlet previously measured at 30C/86F CPU Die previously measured at 42C/107F +3.30 V previously measured at +3.24 +1.50 V previously measured at +1.48 +2.50 V previously measured at +2.46 +5.15 V previously measured at +4.96 +1.20 V previously measured at +1.17 VDD_CPU previously measured at +1.25

Checking Conditions Prior to System Startup

Fan Failures

When the system power is on, all five fans should be operational. The system continues to operate if a fan fails. When a fan fails, the system displays the following message:

router: 00:03:46:%ENVM-3-BLOWER:Fan 2 may have failed

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:

Queued messages: %ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown

For complete descriptions and instructions for the environmental monitor commands, refer to the Cisco

IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications, which are available online.

Chapter 3 Starting and Configuring the Router

Checking Conditions Prior to System Startup

Check the following conditions before you start your router:

• The port adapter is inserted in its slot and the port adapter lever is in the locked position.

• The network interface cable is connected to the port adapter.

• A CompactFlash Disk is installed.

• SFP modules and their optical-fiber cables are installed.

• The optional USB Flash memory module or Aladdin USB eToken Pro key is installed.

• The optional Fast Ethernet Management port cable is installe d.

• The console terminal is turned on.

You a re now ready to start your router. Proceed to the “Starting the System and Observing Initial

Conditions” section on page 3-8.

Starting the System and Observing Initial Conditions

After installing your Cisco 7201 router and connecting cables, start the router as follows:

Step 1 At the front of the router, place the power switch on the power supply in the on (O) position. Step 2 Listen for the fans; you should immediately hear them operating. Step 3 During the boot process, observe the system LEDs. The LEDs on the port adapter go on and off in

irregular sequence. They may go on, go out, and go on again for a short time. On the router, the green STATUS LED comes on and stays on.

Step 4 Observe the initialization process. When the system boot is complete (a few seconds), the processor

begins to initialize the port adapter and the I/O subsystem. During this initialization, the LEDs on the port adapter probably will flash on and off.

The ENABLED LED on the port adapter goes on when initialization is completed, and the console screen displays a script and system banner similar to the following:

Cisco IOS Software, 7200 Software (C7200P-ADVENTERPRISEK9-M), Version

Step 5 When you start up the router for the first time, the system automatically enters the setup facility, which

determines which port adapter is installed and prompts you for configuration information. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt:

--- System Configuration Dialog ---

At any point you may enter a questions mark ‘?’ for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets ‘[]’.

continue with configuration dialog? [yes]:

Configuring a Cisco 7201 Router

You have the option of proceeding with the setup facility to configure the interfaces, or exiting from setup and using configuration commands to configure global (system-wide) and interface-specific parameters. You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.

Many of the port adapter LEDs do not go on until you have configured the interfaces. To verify correct operation of each interface, complete the first- time startu p procedures and configuration, and then refer to the configuration note for the port adapter for LED descriptions and to check the status of the interfaces.

If the system does not complete each of the steps in the startup procedure, proceed to Chapter 5,

“Troubleshooting Initial Startup Problems” for troubleshooting recommendations and procedures.

Configuring a Cisco 7201 Router

Yo u can configure your C isco 7201 router using one of the procedures described in the following sections:

• Performing a Basic Configuration Using AutoInstall, page 3-10

• Performing a Basic Configuration Using the Setup Facility, page 3-10

• Performing a Basic Configuration Using Global Configuration Mode, page 3-20

Follow the procedure that best fits the needs of your network configuration.

OL-11364-04

Note You need to acquire the correct network addresses from your system administrator or consult your

network plan to determine corre ct addresses before you can complete the router configuration.

Before continuing the configuration process, check the current state of the router by entering the show version command. The show version command displays the release of Cisco IOS software that is available on the router. Sample output of the show version command appears in the

“Viewing Your

System Configuration” section on page 3-29.

Cisco 7201 Installation and Configuration Guide

Configuring a Cisco 7201 Router

Performing a Basic Configuration Using AutoInstall

The AutoInstall process is designed to configure the Cisco 7201 router automatically after connection to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be preconfigured to provide the required conf i gurat ion files. The TCP/IP host may exist an ywhere on the netw ork as long as the following two conditions are maintained:

1. The host must be on the remote side of the router synchronous serial connection to the WAN.

2. User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host are enabled.

This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not use AutoInstall unless the required files are available on the TCP/IP host. Refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications for information about how AutoInstall works.

Complete the following steps to prepare your Cisco 7201 router for the AutoInstall process:

Step 1 Attach the appropriate synchronous serial cable to synchronous serial interface 0 on the router. Step 2 Turn the power switch on the power supply to the on (O) position. (This action t urns on AC power to the

router.) The router loads the operating system image from flash memory. If the remote end of the WAN

connection is connected and properly configured, the AutoInstall process begins.

Chapter 3 Starting and Configuring the Router

Step 3 Once the AutoInstall process is completed, use the copy running-config startup-config command to

write the configuration data to the router’s nonvolatile random-access memory (NVRAM). Perform the following step to complete this task.

Step 4 At the # prompt, enter the following command:

Hostname# copy running-config startup-config

Note Completing Step 3 saves the configuration settings that the AutoInstall process created to NVRAM. If

you fail to do this, your configuration will be lost the next time you reload the router.

Performing a Basic Configuration Using the Setup Facility

If you do not plan to use AutoInstall, do not connect the router’s serial (WAN) cable to the channel service unit/data service unit (CSU/DSU). If the WAN cable is not connected, the router boots from flash memory and goes automatically into the setup facility.

Note You can run the setup facility any time you are at the enab le prompt (#) by entering the setup command.

If the serial (WAN) cable is connecte d to the CSU/DSU and the router does not have a configuration stored in NVRAM, the router attempts to run AutoInstall at startup. The router may take several minutes to determine that AutoInstall is n ot set up to a remote TCP/IP host. O nce the rou ter determ ines that AutoInstall is not configured, it defaults to the setup facility.

“Checking the Running

Configuring the Native Gigabit Ethernet Interfaces

The Cisco 7201 router reports the Gigabit Ethernet SFP ports as GigabitEthernet 0/0, GigabitEthernet 0/1, GigabitEthernet 0/2, and GigabitEthernet 0/3. The Cisco 7201 router reports the RJ-45 ports as GigabitEthernet 0/0 and Gigabit Ethern et 0/1. Befo re configuring eith er the GigabitEt hernet 0/ 0 or Gigabit Ethernet 0/1 interfaces, you must first use the media-type interface command to select the media type, sfp or rj45.

Changing the Media Type

To be able to use a particular media type, use Cisco IOS to select the media type. This is done by using the media-type interface command:

media-type { sfp | rj45 } Example:

interface GigabitEthernet 0/0 media-type rj45 end

Configuring the Interface Transmission and Speed Modes

After changing the media type, configure the speed and duplex transmission modes to appropriately match the new interface characteristics. Changing the speed and duplex of a Cisco 7201 router Gigabit Ethernet interface is done using th e speed and duplex interface commands.

OL-11364-04

Tab l e 3-3 Supported Speed and Duplex Settings

Media Type Speed Duplex

1. GE 0/3 only supports full duplex mode.

Cisco 7201 Installation and Configuration Guide

3-15

Configuring a Cisco 7201 Router

When using the sfp media type, there is also the additional negotiation auto command that is used to enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

To turn this negotiation auto feature off (it is on by default), issue the interface command no negotiation auto. This is useful for connecting to other Gigabit Ethernet equipment that does not support IEEE 802.1z autonegotiation. We recommend that a fixed speed and duplex setting should be used.

When the interface is configured for negotiation auto, the interface advertises all modes of which it is capable. The link only comes up if the negotiation process succeeds in finding a common mode between the Cisco 7201 SFP media type and its link partner.

The sfp media type always defaults to 1000-Mbps, full-duplex operation. The only available speed in this mode is 1000 Mbps; there is no difference whether 1000 or auto is selected. GE 0/0, GE 0/1 and GE 0/2 support half and full duplex mode; GE 0/3 only supports full duplex mode.

Note Copper SFP modules are considered to be SFP media types, not RJ-45 media types. GE 0/2 and GE 0/3

are optical ports, whether or not a copper SFP module with an RJ-45 connector, or a standard SFP module is installed.

Chapter 3 Starting and Configuring the Router

Debugging

Note The negotiation auto feature is not supported when using the rj-45 media type and will be

ignored if implementation is attempted. (Autonegotiation is always on in RJ-45 mode.)

When an RJ-45 interface is enabled, it advertises all modes of which it is cap able. Th e li nk on ly co mes up if the negotiation process succeeds in finding a common mode between the Cisco 7201 RJ-45 media type and its link partner.

If you change from the sfp to the rj-45 media type, you must set speed and duplex after you have executed the media type command to ensure the interface operates in the correct mode.

For information on flow control, see the “Gigabit Ethernet Flow Control Information” section on

page A-9.

Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is 0, 1, 2, or 3) and show controllers GigabitEthernet 0/X (where X is 0, 1, 2, or 3).

The output of the show interface command is useful for determining the current operating mode of the interface (speed/duplex/media type) and the current interface statistics.

The output of the show controllers command displays more information specific to the Cisco 7201 router Gigabit Ethernet interface. For e xample, it shows the detected link status, speed, and duplex, and also determines the current status of autonegotiation and the link partners’ abilities (if it is an autonegotiation-capable interface).

3-16

The show controllers command also displays the current operating state of the driver and the Ethernet controller hardware. The show controllers command is a very powerful debugging aid, especially for Cisco engineers should you need help in debugging a problem. If you have any problems with your Gigabit Ethernet interfaces, you will need to provide this information to Cisco for analysis.

Chapter 3 Starting and Configuring the Router

Resetting the Interface

Should you have a problem with your interface and you want to try and reset it, use the command: clear interface GigabitEthernet 0/X (where X is 0, 1, 2, or 3)

Clearing Counters

Interface counters may be cleared (reset) by using the command: clear counters GigabitEthernet 0/X (where X is 0, 1, 2, or 3)

Note Using this command will not reset the interface.

Configuring Port Adapter Interfaces

Following are the steps for configuring interfaces to allow communication over a LAN or WAN. To configure the interface parameters, you need your interface network addresses and subnet mask information. Consult with your network administrator for this information.

Configuring a Cisco 7201 Router

Note Only one port adapter can be installed in the Cisco 7201 router. Following are three examples of three

different interfaces that might be used.

Upgrading ROMmon on the Cisco 7201

Upgrading the rewriteable ROM monitor (ROMmon) allows you to download a new ROMmon image instead of having to replace hardware (Cisco 7201) to get a new image.

There are two ROMmon images: the ReadOnly image that ships with your system (and is always available if you have Cisco 7201 hardware EPROM Version 1.4 and software C7201:Rommon version is

12.3(4r)T2 o r later), and the upgradable ROMmon image that is downloaded from a specified TFTP file location. Y o u can choose to configure the system to point to the upgradable R OMmo n image. At bootup, the system starts with the ReadOnly image and then, if configured, jumps to the upgradable ROMmon image. If the upgradable ROMmon image fails to boot, the router marks this ROMmon image as invalid and reverts to the ReadOnly ROMmon image.

The first time a new ROMmon image is executed, you must allow the system to boot ROMmon before doing any additional resets or power cycling. If the ROMmon-executing process is interrupted, the system interprets this as a bootup failure of the ne w R OMmon image. The router rev erts to the ReadOnly image.

Note The ROMmon upgradable image is marked as invalid if it fails to boot. Do not reset the router when it

is doing an initial bootup.

Upgrading FPGA

A field-programmable gate array (FPGA) device exists on the Cisco 7201. FPGA devices are a type of field-programmable device (FPD) that support separate software upgrades. Whenever a Cisco image is released that supports the FPD feature, a companion FPD image package is also released for that Cisco IOS software release. The FPD image package is available from Cisco.com and is accessible from the Cisco Software Center page where you go to download your Cisco IOS software image.

Replacing or Recovering a Lost Password

This section describes how to recover a lost enable or console login password, and how to replace a lost enable secret password on your Cisco

Note It is possible to recover the enable or console login password. The enable secret password is encrypted,

however, and must be replaced with a new enable secret password.

Overview of the Password Recovery Procedure

Following is an overview of the steps in the password recovery procedure:

Step 1 If you can log in to the router, enter the show version command to determine the existing configuration

Step 2 Press the Break key to get to the bootstrap program prompt (ROM monitor). You might need to reload

the system image by power cycling the router.

Chapter 3 Starting and Configuring the Router

Note T o reco v er a lost password if the Break function is disabled on the router , you must ha ve physical access

to the router.

Step 3 Change the configuration register so the following functions are enabled:

a. Break b. Ignore startup configuration c. Boot from flash memory

Note The key to recovering a lost password is to set the configuration register bit 6 (0x0040) so that

the startup configuration (usually in NVRAM) is ignored. This allows you to log in without using a password and to display the startu p configuration passwords.

Note When powering off the router, wait 30 seconds before powering it on again.

Step 4 Power cycle the router by turning power off and then back on. Step 5 Log in to the router and enter the privileged EXEC mode. Step 6 Enter the show startup-config command to display the passwords. Step 7 Recover or replace the displayed passwords. Step 8 Change the configuration register back to its original setting.

Chapter 3 Starting and Configuring the Router

Details of the Password Recovery Procedure

Complete the following steps to recover or replace a lost enable, enable secret, or console login password:

Step 1 Attach an ASCII terminal to the console port on your router. Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit (9600 8N1). Step 3 If you can log in to the router as a nonprivileged user, enter the show version command to display the

existing configuration register value. Note the value for use later and proceed to log in to the router at all, go to the next step.

Step 4 Press the Break key or send a Break from the console terminal. If Break is enabled, the router enters the

ROM monitor , indicated by the R OM monitor prompt ( power cycle the router (turn t he router of f or unplug the po wer cord, and t hen restore po wer after waiti ng 30 seconds). Then proceed to

Step 5 Within 60 seconds of restoring the power to the router, press the Break key or send a Br eak. This action

causes the router to enter the ROM monitor and display the ROM monitor prompt (

Step 6 Set the configuration register using the configuration register utility; enter the confreg command at the

ROM monitor prompt as follows:

Step 7 Answer yes to the enable “ignore system config info?” question, and note the current configuration

Step 8 Initialize the router by entering the reset command as follows:

rommon2> reset

The router initializes, the configuration register is set to 0x142, and the router boots the system image from flash memory and enters the System Configuration Dialog prompt as follows:

--- System Configuration Dialog --

Step 9 Enter no in response to the System Configuration Dialog prompts until the following message is

displayed:

Replacing or Recovering a Lost Password

The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console login passwords may be encrypted or clear text. Proceed to the next step to replace an enable secret, console login, or enable password. If there is no enable secret password, note the enable and console login passwords, if they are not encrypted, and proceed to

Caution Do not ex ecu te the next step unless you have determined y ou must change or replace the enable, enable

secret, or console login passwords. Failure to follow the steps as shown might cause you to erase your router configuration.

Step 13 Enter the configure memory command to load the startup conf igurati on f il e into running memory. This

action allows you to modify or replace passwords in the configuration.

Router# configure memory

Step 14 Enter the privileged EXEC configure terminal command to enter configuration mode:

Hostname# configure terminal

Step 15 Change all three passwords using the following commands:

Hostname(config)# enable secret newpassword1 Hostname(config)# enable password newpassword2 Hostname(config)# line con 0 Hostname(config-line)# password newpassword3

Chapter 3 Starting and Configuring the Router

Step 17.

Change only the passwords necessary for your configuration. You can remove individual passwords by using the no form of the above commands. For example, entering the no enable secret command removes the enable secret password.

Step 16 You must configure all interfaces to be not administratively shut down as follows:

Hostname(config)# interface gigabitethernet 0/0 Hostname(config-int)# no shutdown

Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces are administratively shut down and unavailable when the router is restarted.

Step 17 Us e the config-register command to set the configuration register to the original value noted in Step 3

or Step 8, or to the factory default value 0x2102 as follows:

Hostname(config)# config-register 0x2102

Step 18 Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode

and return to the EXEC command interpreter.

Caution Do not execute the next step unless you have changed or replaced a password. If you skipped Step 13

through Step 16, skip to Step 20. Failure to observe this caution causes you to erase your router configuration file.

Step 19 Enter the copy running-config startup-config command to save the new configuration to NVRAM. Step 20 Enter the reload command to reboot the router. Step 21 Log in to the router with the new or recovered passwords.
