Service Processor CheckpointsService processor checkpoints are in the range 8xxx to Bxxx. The message OK indicates successfulservice processor testing and initialization. Firmware checkpoints are listed in “Firmware Checkpoints” onpage 140.Note: A spinning (or twirling) slash displays in the upper-right corner of the operator panel display whilesome checkpoints are being displayed. If the slash stops spinning, a hang condition is indicated.Table 1.
