Obtaining the Rescue Image from a Compact Flash Card

Before you remove or install any hardware, review the hardware documentation listed in GUID-824CFC84-F07E-4691-BA46-54553EC2921A.

In addition to recovering the switch using the internal memory card and the management port, there is also support for loading the rescue image to the compact flash card installed in the MSM.

The compact flash card must be file allocation table (FAT) formatted. Use a PC with appropriate hardware such as a compact flash reader/writer and follow the manufacturer‘s instructions to access the compact flash card and place the image onto the card.

Note

This feature is supported only on BlackDiamond 8800 series switches.

To recover the switch, you must remove power from the switch, install an appropriate compact flash card into the MSM, and enter the Bootloader to issue a series of commands.

To access the Bootloader:
1. Remove all power cords from the power supplies switch. There should be no power to the switch.
2. Insert the FAT formatted compact flash card into the compact flash slot of the MSM installed in slot 5/A.
3. Remove the MSM installed in slot 6/B. Place the MSM in a safe location and do not re-install it until you finish recovering the switch.
4. Attach a serial cable to the console port of the MSM installed in slot 5/A.
5. Attach the other end of the serial cable to a properly configured terminal or terminal emulator.
  The terminal settings are:
  - 9600 baud
  - 8 data bits
  - 1 stop bit
  - no parity
  - XON/OFF flow control enabled
6. Provide power to the switch by re-inserting the power cords into the power supplies.
7. Immediately press the spacebar until the BootRom -> prompt appears.
  
  Note
  
  You must press the spacebar key immediately after a power cycle of the MSM in order to get into the Bootloader application.
8. As soon as you see the BootRom -> prompt, release the spacebar. From here, you can begin the recovery process.
To obtain the rescue image that you placed on the compact flash card and recover the switch:
1. Download the ExtremeXOS image that is already on the compact flash card using the following command:
  boot file filename
  
  Where the filename specifies the image file for the BlackDiamond 8800 series switches.
2. At the BootRom -> prompt, press [Return].
  The following message appears: ok to continue
3. Type yes to begin the recovery process. This takes a minimum of seven minutes.
4. After the process runs, the BootRom -> prompt displays the following message:
```
****press enter to reboot****
```
5. Press [Return] to reboot the switch.
  
  The switch reboots and displays the login prompt. You have successfully completed the setup from the compact flash card.
6. Remove the compact flash card installed in the MSM.

After you download the ExtremeXOS image file, the switch installs the software and reboots. After the switch reboots, the switch enters an uninitialized state. At this point, configure the switch and save your configuration. In addition, if you previously had modular software packages installed, you must re-install the software packages to each switch partition. For more information about installing software packages, see Software Upgrade and Boot Options.

If you are unable to recover the switch with the rescue image, or the switch does not reboot, contact Extreme Networks Technical Support.
