The Cisco IOS (Internetwork Operating System) is a robust platform that provides a high level of reliable performance within most network infrastructures. Like most software, the IOS requires updates to resolve security issues, defects and also to add additional features. Updating the IOS on a Cisco WS-C2960S-48TS-L is a straightforward procedure when connected to the Cisco 2960 command line interface (CLI) using a serial console cable.

 

Things You'll Need

  • Microsoft Windows 7 computer with 9 pin serial port, TFTP service installed, and connected to the same network as the Cisco 2960
  • Microsoft HyperTerminal install on the Windows 7 computer
  • Cisco serial console cable
  • Cisco IOS image stored in the root directory of the TFTP service application
  • IP address of the Microsoft Windows 7 computer
  • Privilege Exec mode password for the Cisco Catalyst 2960 switch
