What to Do Next
Proceed to the
“Loading the New System Image” section on page 17
Using Console Download (xmodem) in ROM Monitor to Copy the System Image into Flash Memory
Use console download, a ROM monitor function, when you do not have access to a TFTP server.
For detailed information about the console download function and the
xmodem
ROM monitor
command, see the
Xmodem Console Download Procedure Using ROMmon
tech note.
Prerequisites
•
Download the new Cisco IOS software image to your PC. See the
System Image?” section on page 2
•
Connect your PC to the router console port, and launch a terminal emulator program. For examples
of performing this task on similar routers, see the
Xmodem Console Download Procedure Using
Restrictions
•
If you use a PC to download a Cisco IOS image over the router console port at 115,200 bps, make
sure that the PC serial port uses a 16550 universal asynchronous receiver/transmitter (UART).
•
If the PC serial port does not use a 16550 UART, we recommend using a speed of 38,400 bps or
lower when downloading a Cisco IOS image over the console port.
•
The
xmodem
transfer works only on the console port.
•
You can only use the
xmodem
command to download files to the router. You cannot use
xmodem
to get files from the router.
•
Because the ROM monitor console download uses the console to perform the data transfer, error
messages are displayed on the console only after the data transfer is terminated. If an error occurs
during console download, the download is terminated, and an error message is displayed. If you
changed the baud rate from the default rate, the error message is followed by a message that tells
you to restore the terminal to the baud rate specified in the configuration register.
