Reversing the System Fan
for the P600 Processor Only
NOTE If you are installing any other speed processor, ignore this procedure.
1. Look at the fan in the HP UltraFlow airflow guide. If the fan's label is visible, then you
need to reverse the fan. Continue on to step 2 on the next page.
However, if you do not see the label, then the fan has already been reversed. Skip the
remainder of this procedure.
2. Loosen the top cover of the airflow guide by gently pulling the flanged side outward and
releasing the tabs on the base of the airflow guide.
