www.dell.com | support.dell.com Note: In SFTOS 2.3.1.9, these messages also appear when moving from the routing image to the switching image without resetting the configuration to factory defaults from the Boot Menu. This issue results from the use of unique flash file formats. Use one of the following procedures to resolve this condition: • Clear the configuration in flash by resetting the switch to factory defaults. See Restoring the System to the Factory Default Configuration on page 58. • If the first procedure fails, you can format the flash using the Boot Code Utility menu: During the reload, when prompted, press 2 (Boot Menu), then 6 (Run flash diagnostics). Or press 2, then 30 (Boot Code Utility Menu), then 14 (Format File System). Caution: If you are not patient during the formatting, you WILL corrupt the code by interrupting or rebooting. Recovering from a Software Upgrade Failure When an image is downloaded to flash, as shown in Figure 18-261, SFTOS verifies the image CRC. Switch software can be corrupted during an upgrade by downloading the wrong file to the switch or by deleting the image file. Figure 18-261.
