Chapter 1 Product Overview Functional Overview 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 7204 uses a specific method to assign and control the MAC addresses of its port adapters.
Chapter 1 Product Overview Functional Overview MAC Address 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, refer to the section ““Online Insertion and Removal” section on page 1-25”.
Chapter 1 Product Overview Functional Overview When you remove or insert a port or service adapter in a Cisco 7204 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 and service adapters, noting any removed port adapter interfaces and placing them in the administratively shut down state. 3.

The system will continue 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 shut down threshold, it shuts down the system.
C H A P T E R 2 Preparing for Installation This chapter describes the equipment and site requirements for installing the Cisco 7204.
Chapter 2 Preparing for Installation Safety Recommendations • Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the chassis. Fasten your tie or scarf and sleeves. • The Cisco 7204 with installed AC-input power supplies ships with a three-wire electrical grounding-type plug, which will only fit into a grounding-type power outlet. This is a safety feature. The equipment grounding should be in accordance with local and national electrical codes.
Chapter 2 Preparing for Installation Safety Recommendations Safety with Electricity The port adapters and power supplies are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. However, you must power down the system before removing or replacing the I/O controller and network processing engine.
Chapter 2 Preparing for Installation Site Requirements clothing. Always place the network processing engine, I/O controller, or port adapter component side up on an antistatic surface or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag. Caution • Ensure the I/O controller and network processing engine are fully inserted in their respective chassis slots and their captive installation screws are tightened.
Chapter 2 Preparing for Installation Site Requirements Interference Considerations When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring: • Bad wiring practice can result in radio interference emanating from the plant wiring.
Chapter 2 Preparing for Installation Site Requirements • Any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSUs), or data service units (DSUs) • Cable pinouts if you plan to build your cables Before installing the Cisco 7204, have all additional external equipment and cables on hand. The information listed above is contained in the documentation that is shipped with each port adapter.

C H A P T E R 4 Performing a Basic Configuration of the Cisco 7204 This chapter describes how to perform a basic configuration for your Cisco 7204. The chapter contains the following sections: • Using the Enable Secret and the Enable Password, page 4-1 • Configuring the Cisco 7204, page 4-2 • Implementing Other Configuration Tasks, page 4-11 • Chapter 4, “What Do I Do Now?” This chapter guides you through a basic Cisco 7204 configuration, which is sufficient for you to access your network.
Chapter 4 Performing a Basic Configuration of the Cisco 7204 Configuring the Cisco 7204 An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters; an enable password can contain any number of uppercase and lowercase alphanumeric characters. In both cases, a number cannot be the first character. Spaces are also valid password characters; for example, “two words” is a valid password. Leading spaces are ignored; trailing spaces are recognized.
Chapter 4 Performing a Basic Configuration of the Cisco 7204 Configuring the Cisco 7204 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.

Yes
Chapter 5 Troubleshooting the Installation Troubleshooting Overview Problem Solving with Subsystems The key to solving problems with the system is isolating the problem to a specific subsystem. The first step in solving startup problems is to compare what the system is doing to what it should be doing. Because a startup problem is usually caused by a single component, it is more efficient to first isolate the problem to a subsystem rather than troubleshoot each component in the system.
Chapter 5 Troubleshooting the Installation Troubleshooting Overview – The IO power OK LED comes on immediately and indicates that the I/O controller is receiving DC power from the router midplane. This LED comes on during a successful router boot and remains on during normal operation of the router.
Chapter 5 Troubleshooting the Installation Troubleshooting the Power Subsystem – The RJ-45 link LED comes on only when the Fast Ethernet’s RJ-45 port is receiving a carrier signal from the network. This LED remains off during normal operation of the router unless there is an incoming carrier signal, and does not indicate startup problems. If this LED remains off when starting the router, it is probably a problem with the Fast Ethernet port on the I/O controller.
Chapter 5 Troubleshooting the Installation Troubleshooting the Processor Subsystem – If not, repeat each of the above procedures for the second power supply. Note After powering off the router, wait at least 30 seconds before powering it on again. If you are unable to resolve the problem or you determine that either a power supply or chassis connector is faulty, contact a service representative for instructions.
Chapter 5 Troubleshooting the Installation Troubleshooting the Cooling Subsystem If the I/O controller enabled LED does not go on as expected, make sure the power to the router is turned off, reseat the network processing engine in its slot, and restart the router. If the enabled LED remains off, the system detected a processor hardware failure. (This LED should be on in normal operation.) Contact a service representative for instructions.
Chapter 5 Troubleshooting the Installation Troubleshooting the Cooling Subsystem If you experience trouble with the startup that is not resolved with these procedures, contact a service representative for assistance and further instructions.

Chapter 6 Maintaining the Cisco 7204 Copying a Bootable Image onto a Flash Memory Card Caution Note The following formatting procedure erases all information on the Flash memory card. To prevent the loss of important data that might be stored on a Flash memory card, proceed carefully. If you want to save the data on a Flash memory card, copy the data to a server before you format the card. The following procedure assumes you have already booted your Cisco 7204.
Chapter 6 Maintaining the Cisco 7204 Copying a Bootable Image onto a Flash Memory Card Note • To ensure access to a TFTP sever, you will need to configure at least one network interface using the setup command facility. For instructions on using this procedure, refer to Chapter 4, “Performing a Basic Configuration of the Cisco 7204.” You know the filename of the image you want you want to copy onto the Flash memory card. Following is the procedure for copying a bootable file (called new.
Chapter 6 Maintaining the Cisco 7204 Copying Bootable Images between Flash Memory Cards When the system reloads, it will boot the new.image file from the Flash memory card. This completes the procedure for copying a bootable image onto a Flash memory card. Copying Bootable Images between Flash Memory Cards As future releases of Cisco IOS images become available, you will receive these images either as a file booted from a network server, a file on floppy disk, or a file on a Flash memory card.
Chapter 6 Maintaining the Cisco 7204 Reformatting a Flash Memory Card Step 5 Use the following series of commands to designate the file new.image (which is on the Flash memory card in slot 0) as the default boot image: Router# config t Router(config)# no boot system Router(config)# boot system flash slot0:new.image Router(config)# ^z Router# copy running-config startup-config Router# reload When the system reloads, it will boot the file new.image from the Flash memory card in slot 0.
Chapter 6 Maintaining the Cisco 7204 Replacing or Recovering a Lost Password Step 2 Copy all the files on the Flash memory card to a TFTP server or a secondary Flash memory card. The following example is for copying files to a TFTP server. Refer to “Copying a Bootable Image onto a Flash Memory Card” section on page 6-9 for Flash memory card examples. Router> en Password: Router# copy slot0:image.name tftp Enter destination file name [image.name]: image.
Chapter 6 Maintaining the Cisco 7204 Replacing or Recovering a Lost 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 register value. 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 6 Maintaining the Cisco 7204 Replacing or Recovering a Lost Password Step 6 Set the configuration register using the configuration register utility—enter the confreg command at the ROM monitor prompt as follows: rommon1> confreg Answer yes to the enable “ignore system config info”? question and note the current configuration register settings.

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.
A P P E N D I X A Industry-Standard Wiring Plans When you install more than a few terminals, you face the problem of organizing the wiring. AT&T has devised a uniform scheme for dealing with large numbers of wires for the telephone industry. The scheme uses two color codes—one for large numbers of wires organized in pairs and the other for smaller numbers of wires that may also be organized in pairs. We recommend the use of this wiring scheme whenever possible.
Appendix A Table A-1 Industry-Standard Wiring Plans Telephone Industry 25-Pair Color Code and Pin Numbers (continued) Pair Number Wire Number Solid Color Stripe Color Pin Number 9 1 Red Brown 34 9 2 Brown Red 9 10 1 Red Slate 35 10 2 Slate Red 10 11 1 Black Blue 36 11 2 Blue Black 11 12 1 Black Orange 37 12 2 Orange Black 12 13 1 Black Green 38 13 2 Green Black 13 14 1 Black Brown 39 14 2 Brown Black 14 15 1 Black Slate 40 15 2 Slat
Appendix A Industry-Standard Wiring Plans For smaller numbers of wires, such as wires for an individual telephone station or terminal, you can use a second color-code scheme. Table A-1 lists this color code and the usual correspondence with the paired-wire color code. The alternate color code is included because sometimes the station wire uses the first three pairs of the standard color code (white-blue, blue-white, and so on), while other times it uses the six alternate colored wires.

Appendix B Configuration Register Information Configuration Bit Meanings in ROMmon. If bit 13 is not set, the router will continue to netboot images indefinitely. The default setting for bit 13 is 0. If bit 13 is set, the system boots the boot helper image found in boot flash memory without any retries. The server creates a default filename as part of the automatic configuration processes.
Appendix B Configuration Register Information Configuration Bit Meanings Bit 8 Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the system into the bootstrap monitor, halting normal operation. A Break can be sent in the first sixty seconds while the system reboots, regardless of the configuration settings.
