iLO 2 POST LED indicators

During the initial boot of iLO 2, the POST LED indicators flash to display the progress through the iLO 2
boot process. After the boot process is complete, the HB LED flashes every second. LED 7 also flashes
intermittently during normal operation.
The LED indicators (1 through 6) light up after the system has booted to indicate a hardware failure. If a
hardware failure is detected, reset iLO 2. For the location of the LED indicators, refer to the server
documentation.
A runtime failure of iLO 2 is indicated by HB and LED 7 remaining in either the On of Off state constantly.
A runtime failure of iLO 2 can also be indicated by a repeated flashing pattern on all eight LEDs. If a
runtime error occurs, reset iLO 2.
A sequential flashing pattern on LEDs, 1, 2, 3, 4, 5, 6, 7, and 8, repeating indefinitely, indicates iLO 2
has experienced a failed flash (firmware upgrade) and is in the flash recovery mode. Refer to the "iLO
network flash recovery" section for more information.
