I was just given a preowned x460-48T and am trying to configure or at least access some type of control panel. I am trying to connect from the ethernet port on my laptop to the serial port on the switch. I initially ordered a rj45 to serial port adapter and that didn't work, then ordered a null modem rj45 to serial cable (DTECH DB9 to RJ45 Console Cable Cisco Device Management Serial Adapter, the cross reference is equivalent to Cisco Part Number 72-3383-01, CAB-CONSOLE-RJ45) and cannot get Putty to make a serial connection.
What am I missing here? Any help would be appreciated.
