support.dell.com Information Update 1-56. Press to save these settings and exit the BIOS setup utility. Upon exiting,the system will reboot.7. Run the Dell Diagnostics to obtain information and perform testing on the PERC2cards selected in step 4.8. Upon completion of testing, if additional PERC2 adapter cards are installed, thosecards may be viewed and tested by rebooting and performing steps 1 through 7.Microprocessor ReplacementMicroprocessor latches are intended to provide removal and initial insertion assistance.To complete the removal of a microprocessor, initially use the latch to partiallyremove a microprocessor from its socket. Then grasp the microprocessor and heatsink assembly with both hands and lift it up and out of its socket and guide bracket.To complete the insertion of a microprocessor, firmly press the microprocessor intoits socket until it is completely seated and the latch closes freely.Microprocessor SpeedThe Dell PowerEdge 8450 Systems User’s Guide states that the system supportsmicroprocessors with an internal operating frequency of 500 MHz. However, it shouldbe noted that microprocessors with internal operating frequencies of 800 MHz orhigher are supported.Setting Microprocessor Speed JumpersWhen changing or upgrading microprocessors, you must verify that the microproces-sor speed jumper settings are correctly configured for the new microprocessors.See the system information label and Appendix A of your system’s Installation andTroubleshooting Guide for a list of processor speeds and the corresponding jumpersettings. For microprocessors operating at internal speeds faster than those listed,use the speed jumper setting for the fastest microprocessor listed.Operating System Clock Setting andSystem Event LogIf the system clock setting within the operating system is changed or updated, youshould reboot the system if you require accurate time-stamping of system log events.Otherwise, any system events that are logged after the time change will be time-stamped with respect to the original time setting. Event log time stamps will not bereferenced to the new time setting until the system is rebooted.There are no other issues associated with changing the system time; if the accuratetime-reporting of system events is not a concern, rebooting is not required.
