Installing memory
4 Grasp the screws and pull the formatter board out of the product. Place it on a
flat, non-conductive surface.
5 Remove the DIMM from the antistatic package. Hold the DIMM with fingers
against the side edges and thumbs against the back edge. Align the notches on
the DIMM with the DIMM slot. (Check that the locks on each side of the DIMM
slot are open, or outward.)
See “Installing memory” on page 220 for the maximum amount of memory for
each DIMM slot.
6 Press the DIMM straight into the slot (press firmly). Make sure the locks on
each side of the DIMM snap inward into place. (To remove a DIMM, the locks
must be released.)
