Troubleshooting Errors During Normal Operations It is possible for the controller to encounter errors from which it is unable to recover during normal operations. Specific status LED patterns are used to give a visual indication of any problem. The error pattern returns to the normal setting after the problem has been fixed. These error patterns are listed in Table 30 on page 229. If the controller encounters an unexpected processor exception, the error pattern of 0xE1 will briefly be displayed before the controller reboots itself. Note Note that a ! indicates the LED is ON or Flashing. If the controller encounters a PCI bus fault while running, the error pattern of 0xAA will be displayed solid ON the LED bank . Controller Hardware Reset Pattern Whenever the controller is held in a hardware reset state, all LEDs are on. Therefore, the pattern displayed by the LEDs is 0xFF . Hardware Diagnostics Errors Hardware diagnostics are run during power ON or when a controller module is reset. As diagnostics are run, the LEDs display information indicating which diagnostics are running. The patterns displayed by the LEDs correspond to the Component Code of the component being tested. Note that the codes are 16-bit and the LEDs display the most significant byte first, followed by the least significant byte. The displays cycle approximately once every 2 seconds. If a fatal diagnostic error occurs, the controller will not boot, and the LEDs will continue to display a code that gives an indication of the failed component. See Table 30 on page 229 for these codes. Controller Enclosure Troubleshooting 219
