If you back up the files, they can serve as a reference after the conversion or as a backup if you decide to convert back to CatOS. Issue the copy config tftp command on the Supervisor Engine and the copy start tftp command on the MSFC1 in order to back up the configurations. Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for more information on the use of the copy config tftp and copy start tftp commands to back up configuration files.
Step 5 provides this procedure. If the image is present, go to Step 6. See Step 4 in order to determine if you need to complete this step. Issue the copy tftp bootflash: command or the copy tftp slot0: command in order to download the image to either the SP bootflash or to the PC card in slot0.

Issue the copy tftp bootflash: command in order to download the image to the RP bootflash. Note: You can free up space as necessary on the RP bootflash. Issue the delete bootflash: filename command in order to delete the file.
Then, issue the squeeze bootflash: command in order to erase all deleted files from the device. This setting tells the MSFC1 to boot automatically. If both these settings are correct, go to Step See Step 9 in order to determine if you need to complete this step. Note: If you issued the session module command in order to access the RP, you must issue the exit command instead of Ctrl-C.
In order to avoid the problem, remove either bootflash:switch. Issue these commands:. Issue either the dir bootflash: command or the dir slot0: command.
The command you issue depends on the device to which you previously downloaded the Cisco IOS Software image.
Then, issue the boot bootflash: command or the boot slot0: filename command in order to start the bootup sequence. You need to reformat these Flash devices and replace the images that are on the Flash devices.
Issue the format command in order to format both the Supervisor Engine bootflash and slot0 Flash devices. Note: Remember that the conversion lost the configuration. You need to configure an IP address and possibly static or dynamic routing in order to reestablish connectivity to your TFTP server.
Verify that you can ping your TFTP server from the switch. Verify if the configuration register is set to 0x If not, modify the configuration register to the correct value of 0x This log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot.
Issue the copy config tftp command on the Supervisor Engine and the copy start tftp command on the MSFC2 in order to back up the configurations.
Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for more information on how to use the copy config tftp and copy start tftp commands to back up configuration files. Step 5 provides the procedure.
Then, issue the squeeze bootflash: or squeeze slot0: command in order to erase all deleted files from the device. In order to access the RP, issue either the switch console command or the session module command.
In the case of a large image size, the Supervisor Engine 2 can only store one image in Supervisor Engine bootflash. This requirement depends on the image size.
There are two slots that are available for CompactFlash Type II cards disk0 and disk1 which provide additional storage. A 1 GB MicroDrive is also available. Note: Because some of the latest software images for Supervisor Engine are larger than the bootflash device, a CompactFlash card is recommended.
The keyword for the external CompactFlash memory is disk0 :. The keyword for the internal CompactFlash memory is bootdisk :. This section provides three procedures. Complete the correct procedure for your Supervisor Engine:. Note: The images that this document uses are for example purposes only.
Replace the images with the images that you use in your switch environment. Log your console session as a best practice. The log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot.

Issue the copy config tftp command in order to back up the configuration. For more information on use of the copy config tftp command to back up configuration files, refer to Managing Software Images and Working with Configuration Files on Catalyst Switches. A boot image for the MSFC2 is not a requirement.
However, use of a boot image is recommended, and this procedure uses it. A boot image is a much smaller, scaled-down version of the system image. With a boot image, you can perform a TFTP image transfer if the main system image becomes corrupt or lost.

Step 4 determines the need for this step. Note: You can free up space as necessary on the RP bootflash. Issue the delete bootflash: filename command in order to delete the file. Then, issue the squeeze bootflash: command in order to erase all deleted files from the device. E1 in this case on the RP bootflash. Step 6 determines the need for this step. Note: When you change the configuration register value on the RP to 0x0, the configuration register is automatically synchronized on the SP to 0x0.
Therefore, SP cannot correctly write to bootflash: or slot You need to reformat these flash devices before you continue. Issue the format command in order to format both the bootflash: and slot0: devices. When you formatted the Supervisor Engine Flash devices in Step 12 , the action erased all data on these devices, which included the CatOS image that is used to boot the Supervisor Engine.
You can store these images on either the Supervisor Engine bootflash bootflash: or the PC card slot0: , which depends on the Supervisor Engine Flash capacity and image sizes. These versions appear in boldface in this list:. Note: You can download all the images that this section mentions and a number of other images. The Supervisor Engine 2 ships with 32 MB of bootflash. This requirement depends on the Supervisor Engine and image size. In the case of a large image size, the Supervisor Engine 2 can only store one image in Supervisor Engine bootflash.
This requirement depends on the image size. A PC card is necessary to store these larger images. A 1 GB MicroDrive is also available. Note: Because some of the latest software images for the Supervisor Engine are larger than the bootflash device, a CompactFlash card is recommended.
The keyword for the external CompactFlash memory is disk The keyword for the internal CompactFlash memory is bootdisk:. The necessary image must reside on the TFTP server.
Attach the PC or laptop to the console port of the Supervisor, and run the conversion tool from there. Note: The images that this document uses are for example purposes only. Replace the images with the images that you use in your switch environment. Before the conversion, make sure to refer to the release notes so that the new Cisco IOS software release supports the existing linecards in the chassis. Go to the Software Downloads page on Cisco.
