Downloading to primary or secondary flash using Xmodem and a terminal emulator (CLI)


copy xmodem flash [<primary | secondary>]

Downloads a software file to primary or secondary flash. If you do not specify the flash destination, the Xmodem download defaults to primary flash.


To download a switch software file named E0822.swi from a PC (running a terminal emulator program such as HyperTerminal) to primary flash:

  1. Execute the following command in the CLI:
    switch# copy xmodem flash
    Press 'Enter and start XMODEM on your host...
  2. Execute the terminal emulator commands to begin the Xmodem transfer. For example, using HyperTerminal:
    1. Click on Transfer, then Send File.

    2. Type the file path and name in the Filename field.

    3. In the Protocol field, select Xmodem.

    4. Click on the [Send] button.

      The download can take several minutes, depending on the baud rate used in the transfer.

  3. When the download finishes, you must reboot the switch to implement the newly downloaded software. To do so, use one of the following commands:
    boot system flash {<primary | secondary>}

    Reboots from the selected flash


    Reboots from the flash image currently in use

    For more information on these commands, see “Rebooting the Switches” in the basic operation guide for your switch.

  4. To confirm that the software downloaded correctly:
    switch# show system

    Check the Firmware revision line. It should show the software version that you downloaded in the preceding steps.

If you need information on primary/secondary flash memory and the boot commands, see "Using Primary and Secondary Flash Image Options" in the basic operation guide for your switch.
