Restoring Factory Default Environment Variables
The Boot line determines the location of the image that is used to boot up the chassis after restoring
factory default settings. Ideally, these locations contain valid images, using which the chassis boots up.
While restoring factory-default settings, you can either use a flash boot procedure or a network boot
procedure to boot the device.
When you use the flash boot procedure to boot the device, the boot loader checks if the primary or the
secondary partition contains a valid image. If the primary partition contains a valid image, then the
primary boot line is set to A: and the secondary and default boot lines are set to a Null String. If the
secondary partition contains a valid image, then the primary boot line is set to B: and the secondary and
default boot lines are set to a Null String. If both the partitions contain invalid images, then primary,
secondary, and default boot line values are set to a Null string.
When you use the Network boot procedure to boot the device, the boot loader checks if the primary
partition contains a valid image. If a valid image exists on the primary partition and the secondary partition
does not contain a valid image, then the primary boot line is set to A: and the secondary and default boot
lines are set to a Null string. If the secondary partition also contains a valid image, then the primary boot
line value is set to the partition that is configured to be used to boot the device in a network failure
scenario. The secondary and default boot line values are set to a Null string.
Important Points to Remember
• The Chassis remains in boot prompt if none of the partitions contain valid images.
• To enable TFTP boot after restoring factory default settings, you must stop the boot process in BLI.
In case the system fails to reload the image from the partition, perform the following steps:
1. Power-cycle the chassis (pull the power cord and reinsert it).
2. Hit any key to abort the boot process. You enter uBoot immediately, the => prompt indicates
success.
(during bootup)
press any key
3. Assign the new location to the Dell Networking OS image it uses when the system reloads.
uBoot mode
=> setenv primary_boot f10boot
Boot variable (f10boot) can take the following values:
• flash0 — to boot from flash partition A.
