Cisco Upgrade IOS Configuration Steps
1. LAPTOP: Download TFTP server and verify you know how to use it.
2. Point your directory to the folder where your image is located(see above)
3. Connect Serial or USB to Rollover cable
4. Configure Hyperterminal or Securecrt to :8,9600,none,1
5. Click okay or accept the settings on your terminal emulator
6. Console into switch or router with blue rollover cable
7. Username/ Password prompt: Type proper credentials <enter> and then Type: enable <enter>
8. At the Enable Password prompt: Type proper credentials <enter>
Note: Step 9 through 11 are ONLY if you are trying to access a
NM catalyst switch module onboard a Cisco Router.
If this is not the case then skip the steps 9 through 11. i.e. Start back on step 12.
9. Once you are at the # prompt type: service-module g1/0 session <enter>

and then Type: enable <enter> (This step only for NM-switch if not skip to step 12)
11. At the Enable Password prompt: Type proper credentials <enter>
(This step only for NM-switch if not skip to step 12)
12. configure terminal <enter>
13. interface Fast ethernet switch/slot/port and in our case: interface fastethernet 1/0/1

14. no switchport <enter>
15. ip address ip address/subnet mask ip address 10.10.10.2 255.255.255.0

See Below Image:

address 10.10.10.1 /24 and connect your laptop to the port mentioned above.
20. Then try to ping the the ip on the switchport that you configured above (the .2 address)
