Safety information for leakage sensor module cable

S011

CAUTION

Sharp edges, corners, or joints nearby.

Attention

• Read Installation Guidelines and Safety inspection checklist to make sure that you work safely.

• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

• Depending on the specific configuration, the hardware might look slightly different from the illustrations in this section.

Prepare the following screwdrivers to ensure you can install and remove the corresponding screws properly.

Procedure

1. If you are replacing a processor and reusing the cold plate.
   1. Remove the processor identification label from the cold plate and replace it with the new label that comes with the replacement processor.
   2. If there is any old thermal grease on the cold plate, wipe the thermal grease from the bottom of the cold plate with an alcohol cleaning pad.
2. If you are replacing the cold plate and reusing the processor.
   1. Remove the processor identification label from the old cold plate and place it on the new cold plate in the same location.
      Note

      If you are unable to remove the label and place it on the new cold plate, or if the label is damaged during transfer, write the processor serial number from the processor identification label on the new cold plate in the same location as the label would be placed using a permanent marker.
3. Install the processor.
   1. Slide the processor carrier into the rail frame.
   2. Push the rail frame down until the blue latches lock into place.
   3. Close the retention frame.
   4. Use a Torx T20 screwdriver to tighten the screw.

4. Apply new thermal grease on the top of the processor with a syringe by forming four uniformly spaced dots, while each dot consists of about 0.1 ml of thermal grease.

5. Install the Processor Neptune® Core Module.
   1. Align the cold plate to the processor socket; then, carefully lower the Processor Neptune® Core Module into the chassis.

6. Install the cold plate.
   1. Align the triangular mark and screws on the cold plate assembly with the triangular mark and threaded posts on the processor socket; then install the cold plate assembly on the processor socket.
   2. Fully tighten all the screws in the installation sequence shown on the cold plate assembly.
      Note

      For reference, the torque required for the fasteners to fully tighten is 1.22-1.46 newton-meters (10.8-13.0 inch-pounds).
