Setting Up Multiple Bootloader Carousels
Setting Up DHCTs to Download Images from a
Specific Bootloader Carousel
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.
