About this task

S011

CAUTION

Sharp edges, corners, or joints nearby.

Attention

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

• Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

• 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.

CAUTION

When removing a new Processor Neptune Core Module from the shipping box, lift out the cold plate assembly with the shipping tray attached to prevent thermal grease on the cold plate assembly from damage.

Procedure

1. Install the hose holder to the chassis.
   Figure 1. Installing the hose holder
   

   

   
   
   1. Remove the screws on the system board assembly if needed.
   2. Align the screw holes in the hose holder with the screw holes on the system board assembly and the guiding pins on the holder with the holes on the rear wall.
   3. Install the screws to secure the hose holder to the system board assembly.
2. Install the processor to the Processor Neptune Core Module. For more information, see Install a processor and heat sink.
   Figure 2. Installing the processor
   

   

   
   
   1. Align the triangular mark on the cold plate assembly label with the triangular mark on the processor carrier and processor.
   2. Install the Processor Neptune Core Module onto the processor-carrier.
   3. Press the carrier into place until the clips at all four corners engage.
   Note

   If the server has only one processor installed, generally processor 1, it is required to install a cover to the empty socket of processor 2 before proceeding with further installation.

   1. Rotate the anti-tilt wire bails inward.

   2. Align the triangular mark and four Torx T30 nuts on the cold plate assembly with the triangular mark and threaded posts of the processor socket; then, insert the cold plate assembly into the processor socket.

   3. Rotate the anti-tilt wire bails outward until they engage with the hooks in the socket.

   4. Fully tighten the nuts in the installation sequence shown on the cold plate assembly. Tighten the nuts until they stop; then, visually inspect to make sure that there is no gap between the nut shoulder beneath the cold plate assembly and the processor socket. (For reference, the torque required to fully tighten the nuts is 10 +/– 2.0 lbf-in, 1.1 +/– 0.2 N-m.)

4. Remove the handle from the Processor Neptune Core Module.
   Figure 5. Removing the module handle
   

   

   
   
   1. Rotate the screws as illustrated above to unlock the handle.
   2. Separate the handle from the module.
   Note

   A new Processor Neptune Core Module comes with a handle.

   • To replace an old module with a new one, remove the handle of the new one as illustrated above.

   • To replace processors without changing the module, a handle is not needed. Skip 4 and proceed with further installation.

5. Install the cold plate covers. Press the covers down as illustrated below.

   1. Lower the riser cage into the chassis.
   2. Tighten the screw to secure the riser cage.
8. Connect the cable of the liquid detection sensor module to the connector on the system board assembly. See Internal cable routing.
9. Install the air baffle. See Install the air baffle.
10. Install the top cover. See Install the top cover.
11. Install the server into the rack. See Server replacement.
12. Install the quick connect plugs to the manifolds. See Install the manifold (in-rack system) or Install the manifold (in-row system).
