This is the name the new software image will have when it is loaded onto the router. The image can be named anything, but common practice is to enter the UNIX image filename. Step 7 Erase the Flash device before confirming:. Enter yes to erase the existing software image resident in the router's Flash memory before copying the new one.
Enter no to keep the existing software image. Be sure that you have enough Flash memory to keep both. The copying process requires several minutes; the time differs from network to network. During the copying process, messages are displayed to indicate which files have been accessed.
The exclamation point "! Each exclamation point indicates that ten packets have been transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory. Step 8 Before reloading, verify the correct installation and commands.

In order to register for the Cisco. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration. If your network is live, make sure that you understand the potential impact of any command. Refer to the Cisco Technical Tips Conventions for more information on document conventions. The most commonly used protocol is TFTP. Other protocols include ftp, http, https, scp, and rcp.
If necessary, you can copy an image from one device to another. This section describes how to install a TFTP server, how to establish a console session with the router, and the router boot problems. After the application is installed, you must perform a minimal level of configuration. Download a TFTP server.
Specify the outbound file directory. This is the directory in which the Cisco IOS software images are stored. Most TFTP applications provide a setup routine in order to assist in these configuration tasks. Even if it is possible to connect to the router through a Telnet session, Cisco recommends that you connect directly to the router through the console port because, if something goes wrong during the upgrade, you might need to be physically present next to the router to power-cycle it.
Moreover, the Telnet connection is lost while the router reboots during the upgrade procedure. A rolled cable, usually a flat black cable, connects the console port of the router to one of the COM ports of the PC. If garbage characters appear in the HyperTerminal session, either you have not set the HyperTerminal properties properly or the config-register of the router is set to a non-standard value for which the console connection speed is higher than bps.
In order to check the value of the config-register, issue the show version command. The config-register values appears in the last line of the output. Verify that this value is set to 0x or 0x Note: In order for a configuration register change to take effect, you must reload the router.
When you are sure that the console speed is set to bps on the router side, you should check the HyperTerminal properties. When you are connected to the console port of the router, you might notice that the router is either in ROMmon or Boot mode. These two modes are used for recovery and diagnostic procedures.
If you do not see the usual router prompt, you should use these recommendations in order to proceed with the upgrade procedure installation:. The router boots in ROMmon mode, and this message appears when you issue the dir flash: command:.
This error message displays when the Flash is empty or the filesystem is corrupted. Note: You might also need to consult the Boot Failure procedures specific to your platform. Choose your platform from the Product Support Selector in order to locate these procedures. Look in the Troubleshooting section of each document. These error messages display in the console output when the Flash is empty or when the file system is corrupted.
Copy a valid image on the Flash as described in the procedures provided in this document. Your first step in the upgrade procedure is to select the correct Cisco IOS software release and feature set. This step is very important, and these factors can affect the decision for which Cisco IOS you should select:. All of the devices used in this document started with a cleared default configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.
This can be done with a direct console connection or a virtual Telnet connection. A direct console connection is preferred over a Telnet connection because most disaster recovery procedures require you to be physically present, and a Telnet connection gets lost during the reboot phase of the software installation.
The console connection is made with a rolled cable usually a flat black cable , and connects the console port of the router to the COM port of the PC. Open Hyperterminal on the PC, and use the following settings:.
Note: If you are getting any garbage characters in the hyperterminal, this means you haven't set the hyperterminal properties properly, or the configuration register of the router is set to a non-standard value for which the console connection speed is higher than bps.
Check the value of the configuration register using the show version command shown in the last line of the output and ensure it is set to 0x or 0x It is necessary to reload the router for a configuration register change to take effect. Once you are sure the console speed is set to bps on the router side, you should check the hyperterminal properties as above. Once you are connected to the console port of the router, you might notice that the router is either in ROMmon or Boot mode.
If you do not see the usual router prompt, you should follow the recommendations below to continue with the upgrade procedure. Router boots in ROMmon mode or boot mode, and something similar to the following message appears on the console:. If you see one of the above error messages, it means the Flash card is empty, not formatted, not formatted for the platform, the filesystem is corrupted, or the first image on the Flash card is not a bootable Cisco IOS software image. If the router is in boot mode, you can proceed with the Cisco IOS software upgrade instructions below.
Be careful not to save your configuration while in boot mode as the boot image does not contain full routing functionality. Ping the router to verify that a network connection exists between them. If the router is in boot mode, you may need to set the default-gateway as follows:. Caution: The formatting procedure erases all information on the Flash memory card. To prevent the loss of images and configuration files that might be stored on a Flash memory card, copy the images and files to a TFTP server before you format the card:.
At this point, you need to verify that you have enough space in the Flash memory card to copy the new image. If there is not enough free space, you need to delete some files to make enough space. In some situations, if the image is very large, you may need to delete the current image on the Flash memory card. In the example below, slot0 has two filesystems and bytes of free space. This is not enough to load the new image. In the example below, we delete the second file in order to free enough space for the new Cisco IOS software image.
After deleting the file, use the dir slot0: command to check your free space. The following output shows the free space is still The free space increases when you squeeze the Flash using the squeeze command:. After you have deleted the file, the file is flagged by the operating system. The file is removed permanently once it has been deleted and squeezed. To check whether the file has been deleted and the memory reclaimed, issue the dir slot0: command.
In the above output, you can see that the amount of free Flash memory space has been increased from bytes to bytes. Note: Do not reload or power-cycle the router if there is not a vaild image on the Flash card; this causes the router to go into ROMmon or boot mode.
We recommend that you keep a copy of the router configuration before upgrading. However, this might happen if the right steps are not followed correctly. For example, use the copy rcp flash command instead of the copy tftp flash command. If necessary, you can copy an image from one device to another. When prompted, enter the filename of the Cisco IOS Software image to be installed, as in the following example:.
This is the name the new software image will have when it is loaded onto the router.
