Setting the Main Logic Board Jumpers
The following information supersedes the information presented in the section
"About the Clock Mode Select Jumper" in the Ultra Enterprise 450 Server Owner's
Guide. Contrary to the table in the section, the new Sun Enterprise 450 server main
logic board (501-5673) uses the clock mode select jumpers J2701 and J2702.
Set the clock mode jumper shunts at addresses J2701 and J2702 to correspond to the
speed of your UltraSPARC II CPU module. Verify that the jumper setting is correct
before starting the system.
