Recovery Procedures Chapter 9 Troubleshooting Recovering from Corrupted Software Switch software can be corrupted during an upgrade, by downloading the wrong file to the switch, and by deleting the image file. In all these cases, the switch does not pass the power-on self-test (POST), and there is no connectivity. This procedure uses the XMODEM Protocol to recover from a corrupt or wrong image file. There are many software packages that support the XMODEM protocol, and this procedure is largely dependent on the emulation software you are using. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Connect a PC with terminal-emulation software supporting the XMODEM Protocol to the switch console port. Set the line speed on the emulation software to 9600 baud. Unplug the switch power cord. Reconnect the power cord to the switch. The software image does not load. The switch starts in boot loader mode, which is indicated by the switch: prompt. Use the boot loader to enter commands, and start the transfer. switch: copy xmodem: flash:image_filename.bin When the XMODEM request appears, use the appropriate command on the terminal-emulation software to start the transfer and to copy the software image to Flash memory. 9-26 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide 78-6511-08
