Hardware Initialization Hardware initialization codes are displayed on the LED bank as the hardware is initialized during a power up or reset sequence. If the controller encounters errors during hardware initialization, error patterns are displayed on the LEDs. These error patterns are listed in Table 30 on page 229. Note These status codes are displayed only momentarily and are typically not visible if the controller is operating normally. They are only visible if the firmware "hangs" while executing these functions. Boot Menu Execution Prior to the Boot Menu actually executing, the controller will display a number of status codes indicating various functions being executed (see Table 30 on page 229). Once the Boot Menu is invoked, the controller will cycle through all of the LEDs one by one, and the LED pattern displayed is shown in Table 26. Note Note that a ! indicates the LED is ON or Flashing. Table 26 LEDs Prior to Boot Menu 0x01 0x02 0x04 0x08 0x10 0x20 0x40 0x80 x01, etc. 220 Controller Enclosure Troubleshooting
