Symptom: Switch restarts repeatedly or ends up at switch: prompt.
Fix: You are now in ROMmon. Load a new image via XMODEM (sloooow) or TFTP from ROMmon: c3560ipservicesk9mz1502se11bin upd
rommon 1> IP_ADDRESS=192.168.1.2
rommon 2> IP_SUBNET_MASK=255.255.255.0
rommon 3> DEFAULT_GATEWAY=192.168.1.1
rommon 4> TFTP_SERVER=192.168.1.100
rommon 5> TFTP_FILE=c3560ipservicesk9mz1502se11.bin
rommon 6> tftpdnld
