Error code FRU/actionAll SCSI Errors One or more of thefollowing might be causing the problem:v A failing SCSI device(adapter, drive, controller)v An improper SCSI configuration or SCSItermination jumper settingv Duplicate SCSI IDs in the same SCSIchainv A missing or improperly installed SCSIterminatorv A defective SCSI terminatorv An improperly installed cablev A defective cable1. External SCSI devices must be turned on before you turn onthe server.2. Make sure that the cables for all external SCSI devices areconnected correctly.3. If you have attached an external SCSI device to the server, makesure the external SCSI termination is set to automatic.4. Make sure that the last device in each SCSI chain is terminatedcorrectly.5. Make sure that the SCSI devices are configured correctly.Temperature error messagesNote: See “System” on page 108 to determine which components a field service technician should replace.Message ActionDASD Over Temperature(level-critical; direct access storage devicebay x was over temperature)Ensure that the server is being properly cooled; see “Systemreliability guidelines” on page 12.DASD Over recommended Temperature(sensor x)(level-warning; hard disk drive bay x hadover temperature condition)Ensure that the server is being properly cooled; see “Systemreliability guidelines” on page 12.DASD under recommended temperature(sensor x) (level-warning; direct accessstorage device bay x had undertemperature condition)Ambient temperature must be within normal operatingspecifications; see “Features and specifications” on page 3.DASD Over Temperature(level-critical; sensor for DASD1 reportedtemperature over recommended range)Ensure that the server is being properly cooled; see “Systemreliability guidelines” on page 12.Power supply x Temperature Fault(level-critical; power supply x had overtemperature condition)1.
