I can't seem to figure out how to fix this probelm. Each time I try to boot the system I always end up in the boot command prompt "switch:". I've tried boot flash, removing directories/files but I keep getting a "permission denied" message. I've also tried reinstalling a new IOS image onto the switch using xmodem, and at the last minute I get a message that says there isn't enough space to install the IOS image. Whatever else I do to the switch denies my permission to go any further. How can I go about without constantly getting these permission denied messages?
