Note: You must wait approximately 2.5 minutes after you connect the power
cord of the file module to an electrical outlet before the power-control button
becomes active.
Removing and replacing the thermal grease
The following procedure is for a field replaceable unit (FRU). FRUs must be
installed only by trained service technicians.
About this task
To replace damaged or contaminated thermal grease on the microprocessor and
heat exchanger, complete the following procedure.
Procedure
1. Place the heat sink assembly on a clean work surface.
2. Remove the cleaning pad from its package and unfold it completely.
3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat
exchanger.
Note: Make sure that all of the thermal grease is removed.
4. Use a clean area of the cleaning pad to wipe the thermal grease from the
microprocessor; then, dispose of the cleaning pad after all of the thermal grease
is removed.

5. Use the thermal-grease syringe to place nine uniformly spaced dots of 0.02 mL
each on the top of the microprocessor.
Note: 0.01mL is one tick mark on the syringe. If the grease is properly applied,
approximately half (0.22 mL) of the grease remains in the syringe.
6. Continue with step 9. of the "Installing a microprocessor and heat sink" on
page 150 procedure.
