Cisco-Linksys SRW 248G4 – system firmware recovery

In this article I will describe how to proceed if your firmware upgrade on SRW 248G4 switch failed and the switch then stop working.

I have found only one solution how to recover from this disaster and it is sending a new firmware over PC serial (COM) port using xmodem protocol. A new firmware can be send to the failed switch with the help of Startup menu of the switch. The Startup menu can be entered when the switch is booting.
