9. Remove the memory voltage regulator modules from locations P1-C25, P1-C30, P1-C31, and P1-
C36.
Tip: As you remove parts from inside the system, take notes about the location for each part. It is
important that you replace parts in the exact location from which they were removed.
a) Unlock the levers (A) to release the voltage regulator module from its connector. Refer to the
following image.
b) Rotate the levers in the direction shown.
c) While holding the voltage regulator module by its levers, pull upward to remove the card from its
slot.
d) Place the voltage regulator module on an appropriate ESD surface.
e) Repeat steps "9.a" on page 24 through "9.d" on page 24 to remove the remaining memory voltage
regulator modules.
