Press <F10> to save these settings and exit the BIOS setup utility. Upon exiting,

the system will reboot.

Run the Dell Diagnostics to obtain information and perform testing on the PERC2

cards selected in step 4.

Upon completion of testing, if additional PERC2 adapter cards are installed, those

cards may be viewed and tested by rebooting and performing steps 1 through 7.

Microprocessor Replacement

Microprocessor latches are intended to provide removal and initial insertion assistance.

To complete the removal of a microprocessor, initially use the latch to partially

remove a microprocessor from its socket. Then grasp the microprocessor and heat

sink 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 into

its socket until it is completely seated and the latch closes freely.

Microprocessor Speed

The Dell PowerEdge 8450 Systems User's Guide states that the system supports

microprocessors with an internal operating frequency of 500 MHz. However, it should

be noted that microprocessors with internal operating frequencies of 800 MHz or

higher are supported.

Setting Microprocessor Speed Jumpers

When 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 and Trouble-

shooting Guide for a list of processor speeds and the corresponding jumper settings.

For microprocessors operating at internal speeds faster than those listed, use the

speed jumper setting for the fastest microprocessor listed.

Operating System Clock Setting and

System Event Log

If the system clock setting within the operating system is changed or updated, you

should 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 be ref-

erenced to the new time setting until the system is rebooted.

There are no other issues associated with changing the system time; if the accurate

time-reporting of system events is not a concern, rebooting is not required.
