Disassemble the compute node for recycle

Follow the instructions in this section to disassemble the compute node for recycle.

1. Make preparations for this task.
   1. Turn off the corresponding compute node on which you are going to perform the task.
   2. Remove the compute node from the enclosure (see Remove a compute node from the enclosure).
2. Remove all of the existing components from the compute node and install them into the replacement compute node (see Replace a defective compute node).
   Note

   Make sure to install the drives and memory modules to their corresponding drive bay or slot in the replacement compute node.
3. Remove the CMOS battery (see Remove the CMOS battery (CR2032)).
4. Remove the two M.2 backplane guide pins with a screwdriver.

5. Remove the following 14 screws that secure the system board to the compute node tray.

   • Twelve Phillips #1 screws on the system board (with a torque screwdriver set to the proper torque).

     Note

     For reference, the torque required to fully loosen or tighten the screws is 0.5-0.6 newton-meters, 4.5-5.5 inch-pounds.
   • Two jackscrews on the front of the compute node tray.

     Note

     • Use a 2.5x0.4mm flat head screwdriver to remove and install jackscrews.

     • For reference, the torque required to fully loosen or tighten the jackscrews is 0.059 newton-meters, 0.52 inch-pounds.

7. Tilt the system board at an angle and gently slide the system board backwards and lift it out of the compute node tray.
