from the network port on your computer to one of the front panel fixed ports on the switch.
(Pings and the TFTP transfer will occur via this in-band connection.)

connectivity between the switch and your computer. For example:
C5(su)->ping 192.168.1.2
Then, from your computer, ping the switch.

Note: If the pings are unsuccessful, there may be fire wall or other configuration issues on your
computer. As a first step, try disabling the fire wall on your computer. If that does not resolve the
problem, contact your IT group for assistance.
