Downloading a Firmware Image via the Serial Port

1. With the console port connected, power up the device. The following message displays:

   Boot ROM Initialization, Version 01.00.02
   Copyright (c) 2003 Enterasys Networks, Inc.
   SDRAM size: 1024 MB
   Testing SDRAM.... PASSED.
   Loading Boot Image: 01.00.19... DONE.
   Uncompressing Boot Image... DONE.

2. Once the boot image is finished uncompressing, you receive a message indicating you have 3 seconds to access the bootloader menu by pressing any key. Press a key and the system image loader prompt displays:

   ###You have 3 seconds to access the bootloader menu###
   Press any key to enter System Image Loader menu
   PressAnyKey
   [System Image Loader]:

3. To display help for all the system image loader mode commands, enter a question mark (?):

   [System Image Loader]:?
      ?, help - print this list
      boot - boot (load and go)
      delete - delete an image file
      download - start ZMODEM download
      list - display available images
      log - message log
      setbaud <rate> - set baud rate, (9600,38400,57600,115200)
      setboot <filename> - change boot image file
      showboot - display boot image file
      clearnvram - clear persistent storage
   [System Image Loader]:

4. Use the list command to display the images currently on this device.
5. The baud rate can be set to 9600, 38400, 57600, or 115200. Using the setbaud command, set the baud rate to 115200:

   [System Image Loader]: setbaud 1152000
   ###Change the baud of the terminal program to 1152000###
   [System Image Loader]:

6. Use the download command to start the ZMODEM receive process. Send the image file using the ZModem protocol from your terminal application. (This procedure will vary depending on your application.) When the ZModem download is finished, the following message displays:

   [System Image Loader]: download
   Preparing to receive file...
   **xxxxxxxxxxxxxxxx
   ###Start the ZMODEM transfer from the terminal software###
   Writing file...
   Download successful.
   [System Image Loader]:

7. Use the list command to confirm the images that are currently on the device, and confirm the image currently listed as the boot image. If the current boot image is not the image you want to boot with, use the setboot filename command to set the correct boot image:

   [System Image Loader]: list

8. When a device is booted, the device baud rate is reset to 9600. Reset the terminal application baud rate to 9600 so that it will continue to display output from the device:

   [System Image Loader]: setbaud 9600
   [System Image Loader]:

9. Use the boot command to boot the image:

   [System Image Loader]: boot
   ###The unit will boot normally###
    /flash0/ - Volume is OK

   Note

   If you reboot without specifying the image to boot with setboot as described above, the device will attempt to load whatever image is currently stored in the bootstring via the setboot system command. If the device cannot find the image, or it is not set, it will search through available images and attempt to boot the newest one. If the device finds and successfully boots an image file, it will set the bootstring to the name of that image file.
