5 Provide power to the switch by re-inserting the power cords into the power supplies.
6 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.
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 memory card and recover the switch:
1 Download the ExtremeWare XOS image that is already on the external compact flash memory card
using the following command:
boot file <filename>
Where the
filename specifies the image file for the BlackDiamond 8800 family of switches.
2 At the
BootRom -> prompt, press [Enter]. The following message appears:
ok to continue
Type
YES to begin the recovery process. This takes a minimum of 7 minutes.
3 After the process runs, the
BootRom -> prompt displays the following message:
****press enter to reboot*****
Press [Enter] to reboot the switch. The switch reboots and displays the login prompt. You have
successfully completed the setup from the external compact flash memory card.
4 Remove the external compact flash memory card installed in the MSM.
After you download the ExtremeWare XOS 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 Appendix A, “Software Upgrade and Boot Options.”
If you are unable to recover the switch with the rescue image, or the switch does not reboot, please
contact Extreme Networks Technical Support.
Debug Mode
The Event Management System (EMS) provides a standard way to filter and store messages generated
by the switch.With EMS, you must enable debug mode to display debug information. You must have
administrator privileges to use these commands. If you do not have administrator privileges, the switch
rejects the commands.
To enable or disable debug mode for EMS, use the following commands:
