6. Press <b> to select the option for 115200 baud.
There are two baud rate settings available, 9600 and 115200. Using the higher
baud rate minimizes the time required to download firmware code files.
7. Set your PC’s terminal emulation software to match the 115200 baud rate. Press
Press <Enter> to reset communications with the switch.
8. Check that the switch has sufficient flash memory space for the new code file
before starting the download.
You can store a maximum of only two runtime and two diagnostic code files in
the switch’s flash memory. Use the [D]elete File command to remove a runtime
or diagnostic file.
9. Press <x> to start to download the new code file.
If using Windows HyperTerminal, click the “Transfer” button, and then click
“Send File....” Select the XModem Protocol and then use the “Browse” button to
select the required firmware code file from your PC system. The “Xmodem file
send” window displays the progress of the download procedure.
Note: The download file must be a binary software file for this switch.
10. After the file has been downloaded, you are prompted with “Update Image File:”
to specify the type of code file. Press <r> for runtime code, <d> for diagnostic
code, or <L> for loader code.
Caution: If you select <L> for loader code, be sure the file is a valid loader code file for
the switch. If you download an invalid file, the switch will not be able to boot.
Unless absolutely necessary, do not attempt to download loader code files.
11. Specify a name for the downloaded code file. File names are case-sensitive,
should be 1 to 31 characters, should not contain slashes (\ or /), and the leading
letter of the file name should not be a period (.). (Valid characters: A-Z, a-z, 0-9,
“.”, “-”, “_”)
