I received a new Catalyst 3560-CX Series switch. I attempted to upgrade the switch by copying a new image from a USB flash drive directly onto the switch. A successful process that I've done with 2960X series switches. The process failed and now the original image on the unit is corrupted. I cannot boot the unit. I am only able to get to the "switch:" prompt. I have copied a new image to the unit using the xmodem protocol. The error message now is, "Image failed digital signature verification".
