The HP EX470 media server differs from a standard desktop PC in that it is meant to store data for multiple computers in a single location. The computer is also designed slightly differently than a normal desktop workstation, which changes how internal components are accessed for upgrades. The EX470 ships with an AMD Sempron 1.8GHz processor. If your networked computers need the HP server to run faster and provide swifter file retrieval, the current CPU is capable of being upgraded with a newer processor.
Instructions
1. Shut down the HP EX470 computer and unplug each of the cables attached to the back end of the case. Wait five minutes for the CPU to cool down completely.
2. Grip the right edge of the plastic front panel on the computer case. Pull open the panel to reveal the five drive bays. Grab the black plastic handle at the bottom edge of the fifth drive bay near the bottom of the computer.
3. Lift up the handle and pull the drive out of the computer's case. Repeat the process with each of the other four drives, working from bottom to top. Locate the two Phillips screws on the plastic cover at the lower right edge of the case.
4. Remove both screws with a Phillips screwdriver. Pull the plastic cover toward you slowly until you see the cable attached to the back side of the cover. Unplug the cable and set the cover aside.
5. Loosen and remove the two screws at the bottom of the case holding the motherboard. Pull the entire motherboard toward you until the metal heat sink positioned over the CPU becomes visible.
6. Remove the four screws holding the silver heat sink to the CPU. Lift the heat sink upward and set it upside-down outside the HP computer to gain access to the square CPU.
7. Grip the bar positioned directly below the AMD Sempron CPU. Lift the bar up and push it over to the right to unlock the Sempron from the CPU socket. Pull the CPU off the socket and set it aside.
8. Place your new CPU on top of the empty CPU socket and push the component down so it connects with the socket. Lift up the bar and push it over to the left to lock the component to the socket.
9. Wipe a thin layer of thermal cooling paste on top of the new CPU, using the applicator that came with the cooling paste. Set the silver heat sink on top of the new CPU and replace the four screws to lock it in position. Slide the motherboard back into the computer and replace the two motherboard screws.
10. Reattach the cable to the plastic cover and set the cover on the computer case. Replace the two screws you removed and slide the five drive bays back into place. Push the front cover back into its original position and plug in each of the computer's cables.
