Checkpoints Checkpoints are intended to let users and service personal know what the server is doing, with some detail, as it initializes. These checkpoints are not intended to be error indicators, but in some cases a server could hang at one of the checkpoints without displaying an 8-character error code. It is for these hang conditions, only, that any action should be taken with respect to checkpoints. The most appropriate action is included with each checkpoint. Before taking actions listed with a checkpoint, it is a good idea to look for better symptoms in the Service Processor error log. See Service Processor System Information Menu. SP Checkpoints Service Processor checkpoints are in the range E010 to E0FF. The message OK indicates successful service processor testing and initialization. Firmware checkpoints are listed in "Firmware Checkpoints" on page 3-32. Note: Go to MAP 1540 for any of the following conditions: A four-digit code in the range of E001 through EFFF displays on the operator panal but is not listed in the checkpoint table. A four-digit code displays in the checkpoint table, but does not contain a repair action or FRU listing. All of the FRUs listed in the repair action have been replaced and the problem has not been corrected. Table 3-4 (Page 1 of 3). SP Checkpoints.
