Typically, the size of a .bin file is over 9 MB. Even at a baud rate of 115200 bps, the update takes tens of minutes.

If you select 38400 bps as the download rate, you can skip the step “Change the rate of the serial port on the terminal.”

5)Change the rate of the serial port on the terminal

To ensure communication between the terminal and the switch, the baud rate of the serial port on the terminal should be consistent with that of the console port on the switch.

Step1 Select Call > Disconnect in the HyperTerminal window to disconnect the terminal from the switch.
