Cisco Cisco IOS Software Release 12.2(35)SE 릴리즈 노트

To download the EMI or SMI files for a Catalyst 3750 switch, click Catalyst 3750 software. To obtain 
authorization and to download the cryptographic software files, click Catalyst 3750 3DES 
Cryptographic Software. 

If you are upgrading a switch that is running a release earlier than Cisco IOS Release 12.1(19)EA1c, this 
release includes a bootloader upgrade. The bootloader can take up to 1 minute to upgrade and occurs the 
first time that the new software is loaded. Do not power cycle the switch during the bootloader upgrade.

Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP 
server is properly configured. 

For more information, refer to Appendix B in the software configuration guide for this release.

Log into the switch through the console port or a Telnet session.

(Optional) Ensure that you have IP connectivity to the TFTP server by entering the ping 
tftp-server-address privileged EXEC command:

 tftp-server-address

For more information about assigning an IP address and default gateway to the switch, refer to the 
software configuration guide for this release. 

Download the image file from the TFTP server to the switch. If you are installing the same version of 
software that is currently on the switch, overwrite the current image by entering the archive download 
privileged EXEC command:

[[//location]/directory]/image-name.tar

The /overwrite option overwrites the software image in flash memory with the downloaded one.

The /reload option reloads the system after downloading the image unless the configuration has been 
changed and not saved.

For //location, specify the IP address of the TFTP server.

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory 
and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite 
the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/c3750-i9-tar.121-14.EA1.tar

You can also download the image file from the TFTP server to the switch and keep the current image by 
replacing the /overwrite option with the /leave-old-sw option.

For detailed recovery procedures, refer to the “Troubleshooting” chapter in the software configuration 
guide for this release.
