Next Dr. Jones had me start working on nod 22. He disconnected the power and Ethernet cables and we removed nod 22 from the rack. This time because of my experience with the Geo nodes I had no trouble taking out the motherboard, memory, and expansion cards. The hard drives were more difficult to remove. There were four of them in two bays. One of the bays had been next to the motherboard and just had to be unscrewed from the case, but the other was linked to the bay for the floppy and CD drives. The other bay had to come loose before the hard drives could be removed.

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.

I took the motherboard out of nod 22.
