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.

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).
