Install Guide

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.
