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.

The image can be named anything, but common practice is to enter the same image filename. After you have successfully transferred the file, you should verify that the file is in slot0. Verify that the name and the file size are correct. After copying the image through TFTP, you may need to tell the router which image to load at bootup. At this point, the new image is now in slot0. You need to set the router to boot the new image. By default, the router boots the first file in Flash.

The order in which Flash is searched is disk0:, disk1:, slot0:, slot1:, and finally bootflash:. The default is enabled when there are no boot commands in the configuration, or the boot statement is inaccurate. Option 1 : Check to see if you have any boot commands defined in your configuration by issuing the show running-config command. In the example below, the boot statement is set to boot system flash slot0:rsp-jsv-mz.

Note: The show bootvar command replaces the show boot command. See the show bootvar command. Step 6 Specify the destination filename:. 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. Verify that the image is properly installed and that the boot system commands point to the proper file to load. To reload the image, type:. Step 9 Use the show version command to verify that the router is running with the proper image.

The following documents on Cisco. The table below provides command options for copying a system image from one device to another. Methods vary according to different platforms. Step 1 Display the system Flash directory with the show flash command:. The example below provides the command sequence to use:. Step 3 After the TFTP server is configured, you can download the specified image from the router using the copy tftp flash command, as if it were a classic TFTP server.

Password: password. Router copy tftp flash. Address or name of remote host [ Source file name? Destination file name?

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:. Interfaces and modules support: You must ensure that the new Cisco IOS supports all the interfaces and modules in the router. The file system type "flash" or "disk" is used to store the Cisco IOS image. The show file system command output shows the list of file systems available on the router.

It should have sufficient space to store the Cisco IOS image. This method saves time if you must roll back the Cisco IOS. Backup the configuration from the router because some of the Cisco IOS releases add default configurations. This newly added configuration may conflict with your current configuration.

Compare the configuration of the router after the Cisco IOS upgrade with the configuration backed up before the upgrade. If there are differences in the configuration, you must ensure they do not affect your requirements. In order to achieve this connection, the router interface and the TFTP server must have an IP address in the same range or a default gateway configured. Cisco recommends that you keep a backup of the router and access server configuration before you upgrade.

However, this situation might happen if the right steps are not followed properly. Note: In this section you are presented with three examples that describe how to copy the Cisco IOS image. You can use any one of these methods in order to copy the image. Upgrade the new image from a TFTP server. Use the copy tftp: flash: command in order to copy the image from TFTP server to the flash. The copy process takes several minutes. This time differs from network to network. When the copy process is in progress, messages are displayed that indicate which file has been accessed.

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.
