Then, change the configuration register back to the default. Issue the dir bootflash: command, or the dir disk0: command, or the dir disk1: command.
Then, issue the boot bootflash: command, or the boot disk0: command, or the boot disk1: filename command in order to start the bootup sequence. Change the configuration register of the SP from 0x0 to 0x Issue the show bootvar command again. This output seems to show that all the variables are set and that you can boot the switch automatically. However, if you reload the router at this point, you end up in SP ROMmon because the configuration register value for the SP that you set in Step 9 is still 0x0.
Issue the remote command switch show bootvar command in order to verify this statement. The command displays the current environment variable settings on the SP. Issue this set of commands on the RP in order to change the configuration register settings on the SP:.
Issue the copy config tftp command on the Supervisor Engine and the copy start tftp command on the MSFC2A in order to back up the configurations. Issue the copy tftp bootdisk: command or the copy tftp disk0: command in order to download the image to either the SP bootdisk or to one of the flash cards. Issue the format disk0: command in order to format CompactFlash on a Supervisor Engine Issue the delete bootdisk: command or the delete disk0: filename command in order to delete the file.
You do not need to issue a command in order to erase deleted files from the device. Issue the dir bootdisk: command or the dir disk0: command. Then, issue the boot bootdisk: command or the boot disk0: filename command in order to start the bootup sequence. This output seems to show that all the variables are set and that you can automatically boot the switch.
This section describes how to troubleshoot common issues that occur during the system software conversion. If you try to boot Cisco IOS Software from disk0 or slot0 during the conversion process, you can receive an error message similar to this:. This error message can be hardware or software related, and can result in a boot loop or the switch getting stuck in ROM Monitor ROMmon mode. This issue can be caused by a software image with a bad checksum. This issue can also be due to a hardware fault, but the error message does not indicate which hardware component causes the problem.
This section outlines common reasons that the standby Supervisor Engine module does not come online and how to solve each problem. You can determine that the Supervisor Engine module does not come online in one of these ways:. The output of the show module command shows the status as other or faulty. Console in to the standby Supervisor Engine in order to determine if it is in ROMmon mode or in continuous reboot. For example, a Supervisor Engine can fail to come online in a situation in which:.
In this case, the second Supervisor Engine fails to come online because the redundancy mode is enhanced high system availability EHSA by default.
The standby Supervisor Engine fails to negotiate with the active Supervisor Engine. You must console in to the standby Supervisor Engine in order to recover it. Make sure that the Supervisor Engine module is properly seated in the backplane connector.

Check whether your switch supports the requirements. You can also issue the show version command on the Supervisor module.
Refer to these documents in order to upgrade boot ROM on Supervisor modules:. You can use any TFTP server that can be installed on any platform. The TFTP server root directory must be the directory to which the software image is downloaded.
You can download the images to the default root directory of the TFTP server or change the root directory path to the directory in which the software image resides. Connect a console cable between the switch console port and the PC in order to access the switch command-line interface CLI. Note: You can upgrade the switch through remote Telnet access. But, you lose Telnet connectivity when the switch reloads during the software upgrade.
You can re-establish the Telnet session when the switch loads with the new image. But, in order to troubleshoot in case of failure, you must have local console access. Cisco recommends a switch upgrade through console access. If your upgrade procedure fails due to reasons such as insufficient memory or not enough space on the bootflash of the switch to support the new image, you can always recover the switch to normal mode with the same image that was present in the switch. If you lose the switch configuration for any reason, you can always restore the configuration from the TFTP server.
Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for information on how to manage the configuration files and software images:. If you modify your configuration, make sure to issue the write memory command in order to copy the current configuration to startup configuration and perform the backup. You can issue the copy bootflash: tftp command in order to copy the current software images from bootflash to the TFTP server. If you want to copy the current software images from the external flashcard to the TFTP server, you can use the copy slot0: tftp command on Supervisor Engine 1 or 2.
On the Supervisor Engine , use the copy disk0: tftp or copy disk1: tftp commands. Issue the write memory or copy run start command before you take the backup of the configuration file in order to avoid this error.
This procedure uses the bootflash. This sample scenario uses IP address Ensure that you have enough space available in the bootflash in order to copy the new image from TFTP server into the bootflash. You can check the size of the new image on the PC on which the image resides. Copy the new software image into the bootflash from TFTP server and verify if the image is properly copied.
Check if the file size of the new image matches exactly the size mentioned on the software center on Cisco.
