I've been handed a switch that only boots to rommon. When I run the dir bootflash: command I see that the IOS has been deleted. No worries this switch is not supporting anything yet. Can you point me to a link that will help me load an IOS back on the switch? I have searched the forums with no luck for this model switch.
Please take a look at the following link (4900 uses the same IOS as the 4500).
