attribute. If you download a valid file with the same name as the deleted file to the flash memory, the file
will possess the main attribute.
After the Boot ROM of a switch is upgraded, the original default app file has the main attribute.

Booting with the Startup File

The device selects the main startup file as the preferred startup file. If the device fails to boot with the
main startup file, it boots with the backup startup file.
For the Web file and configuration file, 3com may provide corresponding default file when releasing
software versions. When booting, the device selects the startup files based on certain order. The device
selects Web files in the following steps:
1) If the default Web file exists, the device will boot with the default Web file;
2) If the default Web file does not exist, but the main Web file exists, the device will boot with the main
Web file;
3) If neither the default Web file nor the main Web file exists, but the backup Web exists, the device
will boot with the backup Web file;
4) If neither of the default Web file, main Web file and backup Web exists, the device considers that no
Web file exists.
For the selection of the configuration file when the device boots, refer to the Configuration File
Management part in this manual.
