Installing the Cache

Once you have the case removed, plug in the system's power cord. The power cord will serve as a ground for the computer. If you have a grounding strap, clip it to the metal frame of the computer and put it on your wrist. If you do not have a grounding strap, make certain you touch the power supply located in the back right corner of the computer before you touch any cards inside the computer. Do not touch the metal contacts on the cache card. When installing a cache card, be certain you push the card firmly into the slot. You should not see the metal contacts if the card is correctly installed.
