I purchased a WS-c1900 swtich from ebay and was having trouble connecting to the console so I try to update the firmware to see if that would allow me to connect w/o using a null modem cable. When trying to upgrade to v9.00.04, it erase the old firmware and return a error message " closed by remote host". Now I have a cisco brick that needs a firmware. If someone can send me firmware v5 or higher. I will very appreciate it. thanks in advance.
