220 Controller Enclosure Troubleshooting

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.
