Changes

When I finished emptying and cleaning the nod 22 case, Dr. Jones showed me how to install the motherboard, CPU, CPU fan, and memory. Dr. Jones said the motherboard should remain in the anti-static bag as long as possible, and when it comes out it should be on top of the bag while you install the processor. He said it is important not to touch the pins in the place where the processor should sit. Also, I should hold the CPU by its edges not the upper and lower surfaces. The arrow on one corner of the processor should be aligned with a similar marking on the motherboard. After installing the processor, he installed the CPU fan. The pins for holding the fan to the motherboard are difficult to work with. When one goes down, another one or two pop up. Dr. Jones said I should turn the pins in the direction opposite to the arrow before turning the way the arrow indicated. Finally he installed the memory, which is the most vulnerable to damage from electrostatic shock. I should avoid touching the contacts and hold onto the heat sink while installing it. The memory can go into its DIMM channel only facing one direction. The older memory cards did not have a heat sink, but the new 8 GB cards did.

Dr. Jones connected some cables to the motherboard and left me to work on nodes 21 and 24. I tried to imitate what he did and did it mostly right, but I connected the CPU fan to the system fan connector. When the hard drives came, I installed those and connected them to the wrong SATA port. I should have chosen SATA 0. Except for those mistakes, I installed the new hardware correctly.

I took the motherboard out of nod 22.
