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. Press esc key to abort the boot process (while the system prompts to)

You enter BLI immediately, as indicated by the BOOT_USER # prompt.

press any key

3. Assign the new location of the FTOS image to be used when the system reloads.
