About this task

Safety information for leakage detection sensor module cable

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.

• Keep static-sensitive parts in their static-protective packages until installation to prevent exposure to static electricity. Handle the parts with an electrostatic-discharge wrist strap or other grounding systems. Place the parts on a static-protective surface.

CAUTION

When removing a new NeptCore 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.

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

Procedure

1. Prepare your server.
   1. Install the hose holder to the chassis.
      Figure 1. Installing the hose holder
      

      

      
      

      1. Loosen the screw on the system I/O board and processor board.

      2. Align the screw holes on the hose holder to the system I/O board and processor board. And align the guiding pin of the holder to the rear wall.

      3. Tighten the screw to secure the holder to the system I/O board and processor board.

   2. Open the hose holder cover.
      Figure 2. Opening the holder cover
      

      

      
      

      1. Loosen the thumbscrew on the hose holder.

      2. Open the latch.

2. Make sure you have an alcohol cleaning pad available.
   Attention

   If there is any old thermal grease on the processors, gently clean the top of the processors with an alcohol cleaning pad.
3. Install the processor to the NeptCore module. For more information, see Install a processor and heat sink.
   Figure 3. 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 NeptCore module onto the processor-carrier.

   3. Press the carrier into place until the clips at all four corners engage.

   Note

   If the server only has 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.

4. Install the processor-NeptCore module to the system board assembly.
   Figure 5. Installing the NeptCore module
   

   

   
   

   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 Torx T30 nuts in the installation sequence shown on the cold plate assembly. Tighten the screws until they stop; then, visually inspect to make sure that there is no gap between the screw shoulder beneath the cold plate assembly and the processor socket. (For reference, the torque required for the fasteners to fully tighten is 0.9-1.3 newton-meters, 8-12 inch-pounds.)

5. Remove the module handle from the NeptCore module.
   Figure 6. Removing the module handle
   

   

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

   A new NeptCore module comes with a handle.

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

   2. To replace processors without changing the NeptCore module, a handle is not needed. Skip 5 and proceed with further installation.

6. Install the cold plate covers. Press the cover down as illustrated below.

7. Place the hoses, the leakage detection sensor module and the cable.
   Figure 8. Placing the hoses and module
   

   

   
   

   Note

   Figure 9. Installation details
   

   

   
   

   • The hoses: place the middle part of the hose against the blue latch; and insert the 1 outlet and 2 inlet hoses into the holder.

   • The leakage detection sensor module 3: Insert the module to the holder beside the hoses. And make sure that the side with a status LED is up and route the cable as illustrated above.

   • For leakage detection sensor module working status, see LED on the leakage detection sensor module.

8. Close the hose holder cover.
   Figure 10. Closing the cover back
   

   

   
   
   1. Close the cover in and align the screw hole.
   2. Tighten the screws.
9. Connect the leakage detection sensor module cable of the NeptCore module to the connector on the system board assembly. See Internal cable routing.
10. Install the top cover. See Install the top cover.
11. To install the server into the rack, see Install the server to the rack (friction rails) and Install the server to the rack (slide rails).
12. To install the quick connect plugs to the manifolds, see Install the manifold (in-rack system) or Install the manifold (in-row system).
