Automatic Synchronization Of Configuration Files; Accessing The Bootloader - Extreme Networks ExtremeWare XOS Guide Manual

Automatic Synchronization of Configuration Files

On a dual MSM system, ExtremeWare XOS automatically synchronizes all of the configuration files
from the primary MSM to the backup MSM if the switch detects that the backup MSM's configuration
file contents are different from the primary MSM. You do not configure this behavior.
The switch deletes the old configuration files on the backup MSM only upon a successful file
synchronization. If an error occurs, the switch does not delete the old configuration files on the backup
MSM. For example, if you install a backup MSM that contains different configuration files from the
primary MSM, the old configuration files are deleted after a successful bootup of the backup MSM.

Accessing the Bootloader

The Bootloader of the switch initializes certain important switch variables during the boot process. In
the event the switch does not boot properly, some boot option functions can be accessed through the
Bootloader.
Interaction with the Bootloader is required only under special circumstances and should be done only
under the direction of Extreme Networks Customer Support. The necessity of using these functions
implies a nonstandard problem which requires the assistance of Extreme Networks Customer Support.
To access the Bootloader menu, follow these steps:
1 Attach a serial cable to the console port of the switch.
2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator,
power cycle the switch, and press the spacebar key on the keyboard of the terminal during the
bootup process.
NOTE
To access the Bootloader, you have to 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
