Today’s tech article covers the process of removing a Dell PowerEdge 2950 system board.
To start out, open up your case and unplug all connected cables. Once you are in there, the first thing is to lift the black shroud that is covering the CPUs and RAM (Fig. 1). You may need to move the DVD drive cable that may be routed through it, depending on the drive you have in your machine.
Once you get the shroud lifted, you should see the CPU and RAM area of the board (Fig. 2). I find it easiest to remove them now. Remove all sticks of RAM as well as the processors. Be sure, that with the processors, you watch out for the pins in the motherboard sockets. They are fragile and prone to bending if accidentally touched.
At this point, also remove any PCI expansion cards that are connected to the rear of the machine. Next, lift out the two risers in the rear (highlighted in red in Fig. 3-A) and remove the raid controller from the front internal storage slot (Fig. 4). With the raid controller removed, you can now lift out the side plane. It will be connected to the front LED panel. I usually just leave it plugged in and hanging.
Now, lift out the plastic fan mounts (Fig. 5). This will allow you to remove the backplane by pulling up on the blue tab. Make sure all drives are pulled out enough so that they are completely detached from the backplane.
Lastly, pull your power supplies out enough so they are no longer connected to the board. At this point, you should have removed all of the components that needed to be.
Finally, you will notice a blue tab on the mainboard that can be pulled up (the tiny yellow square next to the smaller riser in Fig. 3-B). Pull this tab up and pull the board towards you and the front of the case. It will reach a point where it can’t move anymore. You will be able to lift up and out of the case. This completes the removal of the system board in the Dell PowerEdge 2950 server.
