Console Cabling

• The only Physical option to access the Networking device via Physical Console port to access the Cisco OS's 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
