Cisco Cisco IOS Software Release 15.0(1)SE

Download the image you identified in Step 1. 

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

For more information, see 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 this privileged EXEC 
command:

Switch# ping tftp-server-address

For more information about assigning an IP address and default gateway to the switch, see 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 this privileged EXEC 
command:

Switch# archive download-sw /overwrite /reload 

[[//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/imagen-name.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 additional recovery procedures, see the “Troubleshooting” chapter in the software configuration 
guide for this release.

You can assign IP information to your switch by using these methods:

The CLI-based setup program, as described in the hardware installation guide.

The DHCP-based autoconfiguration, as described in the software configuration guide.

Manually assigning an IP address, as described in the software configuration guide.
