Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

After you have added a bootloader source to the DNCS, set up DHCTs to download images from a specific
bootloader carousel.

Important: When you set up multiple bootloader carousels, send each DHCT image using only one bootloader
source. Attempting to send the same DHCT image to two different bootloader sources at the same time will
cause the system to display a Save Failed error message when saving the image to the second bootloader
source.
