I am trying to install a Cisco 7960 at my home office. I purchased the unit new off ebay. The previous owner says he uploading the 7.5 firmware on the unit but never used it.
When I power on the unit, the top screen says, "universal application loader" and the bottome says, "configuring vlan," then it goes to "configuring IP," for about 5 minutes, then it goes to "protocol application invalid." What does this mean? Can someone please help?
Thanks in advance for any advice or help.
