I have a 3Com 4500 managed switch. During the configuration process, I managed to use most of the memory of the device. In the process, the boot file and application file have been deleted. I have tried several times to reload the files to the device, but to no avail. It says there is not enough flash memory available to load the 2 files. With the application files active, I was able to format the memory and reinstall the files. Now that the app is not available, I cannot format the flash memory. The boot menu does not allow formatting of memory, only copying of files to the device. Did I brick this switch?
