OL-4215-01
Downloading Software
• If you do not have a SmartNet contract, go to this URL and follow the instructions to register on
Cisco.com and download the appropriate files:
http://www.cisco.com/public/sw-center/sw-lan.shtml
To download the SMI and EMI files, select Catalyst 3750 software.
To obtain authorization and to download the crypto software files, select Catalyst 3750 3DES
Cryptographic Software.
Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure the TFTP server
is properly configured.
For more information, refer to Appendix B in the software configuration guide for this release.
Step 4 Log in to the switch through the console port or a Telnet session.
Step 5 Ensure that you have IP connectivity to the TFTP server by using this privileged EXEC command:
Switch# ping
tftp-server-address
For more information about assigning an IP address and default gateway to the switch, refer to the
Catalyst 3750 Switch Software Configuration Guide.
Step 6 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 using this privileged EXEC
command:
archive download-sw /overwrite /reload tftp:[[//
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 been 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.
Recovering from a Software Failure
Switch software can be corrupted during an upgrade, by downloading the wrong file to the switch, and
by deleting the image file. In all of these cases, the switch does not pass the power-on self-test (POST),
and there is no connectivity. You can use the XMODEM protocol to recover from this failure.
For detailed recovery procedures, refer to the “Troubleshooting” chapter in the software configuration
guide for this release.
