Note: Errors reported against the RealTime Clock can be caused by lowbattery voltage and (more rarely) poweroutages that occur during normalsystem usage. These errors arewarnings that the Real Time Clock datacontent needs to be re-established anddo not require any FRU replacementunless the error is persistent. Whenone of these errors occurs, thepower-on password and time and dateinformation have been lost. To set/restore a power-onpassword, use the SMS utility. To set/restore the time and date,use the operating system facility.If the error is persistent, replace thebattery.If the error is persistent after batteryreplacement, replace the system board.(See notes on page 3-1.)3-10 7043 43P Series Service Guide
