Cisco Cisco IOS Software Release 12.2(35)SE

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/c3750me-i5-tar.122-46.SE.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.

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 these failures.

For detailed 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 Express Setup program as described in the Catalyst 3750 Metro Switch Getting Started Guide.

The CLI-based setup program as described in the Catalyst 3750 Metro Switch Hardware Installation 
Guide.

The DHCP-based autoconfiguration as described in the Catalyst 3750 Metro Switch Software 
Configuration Guide.

Manually assigning an IP addresses described in the Catalyst 3750 Metro Switch Software 
Configuration Guide.
