# Console Cabling

* The only Physical option to access the Networking device via Physical Console port to access the [Cisco OS's CLI](https://app.gitbook.com/@mudassirs46/s/network-fundamentals/~/drafts/-MRZ8l67L5MHnaQIEh9W/cisco-cli).
* Console Access requires Physical connection between PC & Physical Console port of the Networking device as well as the software on the PC to transmit Data. 
* **Console Cabling to the Switch is divided into 3 different categories:**
  1. **New PC Connector (USB Type A port) & New Switch Connector (USB Type Mini-B port) (USB Cable)**
  2. **Old PC Connector (Serial port DB-9 connector) & Old Switch Connector (RJ45 port) (Rollover Cable)**
  3. **New PC Connector (USB Type A port) & Old Switch Connector (RJ45 port) (Converter was used between Rollover & USB Cable)**

### Pinouts for Rollover Cable (Old PC DB-9 Serial Port  - Old Switch RJ 45 Port):

* Rollover Cable uses all the 4 pairs of 8 Wires:
* In the  rollover pinout the wire rolls at pin 1 to pin 8, pin 2 to pin 7, pin 3 to pin 6, and so on.

#### The default Console Port Settings are:

(last 3 parameters are referred as 8N1) ■ 9600 bits/second ■ No hardware flow control ■ 8-bit ASCII ■ No parity bits ■ 1 stop bit
