Troubleshooting Troubleshooting Power On Sequence Test Power On Sequence Test When the disk array is powered on, it goes through a power on sequence test, during which time various numbers are displayed on the front panel. The numbers step higher as each initialization step is completed. The changing sequence numbers assure you that the disk array is performing the various power-on tests. When the tests have all completed, the front panel will display the word "ready." If the word "ready" is not eventually displayed, the sequence number at which the power on stops will help diagnose what might have went wrong. Sequence Code 1 4 6 10 12 16 20 22 24 26 28 30 32 34 36 38 40 42 Table 9.
