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 NeptAir 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. Install the radiator tray to the chassis.
   Figure 1. Installing the radiator tray
   

   

   
   

   1. Place the tray evenly into the chassis and then move it to the right so that the screw hole on the tray aligns with the hole on the chassis.

   2. Tighten the screw.

2. Separate the NeptAir module from the shipping tray.
   
   

   

   
   
   1. Loosen the six screws on the NeptAir module shipping tray.
   2. Lift the NeptAir module by the module handle (NeptAir heat sink bracket) to separate the module from the shipping tray.
3. 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.
4. Install the processor to the NeptAir module.
   
   

   

   
   

   1. Align the triangular mark on the cold plate assembly label with the triangular mark on the processor carrier and processor.

   2. Install the NeptAir module onto the processor-carrier.

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

   Note

   If your 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.

5. Open the NeptAir module handle.

6. Install the processor-NeptAir module to the system board assembly.
   
   

   

   
   

   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 and the radiator. 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.)

7. Rotate the NeptAir module handle down.
   
   

   

   
   

   Note

   For leakage detection sensor module working status, see LED on the leakage detection sensor module.
8. Connect the leakage detection sensor module cable and pump cables of the NeptAir module to the connector on the system board assembly. See Internal cable routing.
9. 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).
