Unable to connect laptop RJ45 to serial port X460-48T

[Landshark77]

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.

Hi Landshark,

your ethernet port of the laptop is not a serial port so this won’t work. I doubt that your laptop has a serial port, so what you need is an USB → Serial Adapter. Personally I use an Delock 61856 which uses the chipset “Prolific PL2303RA”.

Edit: I just noticed that the X460-48t does not have an RJ45 serial port, so you can ignore the following paragraph. All you need is a normal serial cable (DB9 to DB9) to connect from your USB-Serial Adapter to the switch.
