Setting Up Multiple Bootloader Carousels
3 Configure set-tops to use the correct bootloader carousel when downloading
images. For assistance, go to Setting Up DHCTs to Download Images from a
Specific Bootloader Carousel (on page 148).
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.
