Integrated Dell Remote Access Controller 9 User's Guide

iDRAC supports two operating system images to make sure a bootable iDRAC. In the event of an unforeseen catastrophic error and you lose both boot paths:

• iDRAC bootloader detects that there is no bootable image.
• System Health and Identify LED is flashed at ~1/2 second rate. (LED is located on the back of a rack and tower servers and on the front of a blade server.)
• Bootloader is now polling the SD card slot.
• Format an SD card with FAT using a Windows operating system, or EXT3 using a Linux operating system.
• Copy firmimg.d9 to the SD card.
• Insert the SD card into the server.
• Bootloader detects the SD card, turns the flashing LED to solid amber, reads the firmimg.d9, reprograms iDRAC, and then reboots iDRAC.
