Upgrading Your System 4-17
Removing DIMMs
Remove DIMMs from their sockets as follows.
1. Power off the system and remove the right side panel as described earlier in
this chapter.
2.
Remove the metal bracket supporting the memory board. The support
bracket is secured to the chassis by a pin. Release the support bracket by
pulling the two fasteners towards you (listen for two clicks). Grasp the left
side of the support bracket and swing it away from the chassis to remove it.
Set the support bracket aside for later installation.
3.
Open the ejectors on both sides of the memory board (see Figure 4-9).
Holding the memory board by its edges, carefully pull it out until the edge
connectors are free. Place the memory board on an antistatic surface.
Note:
Use extreme care when removing a DIMM. Hold
DIMMs only by their edges. Place them on an antistatic
surface; do not slide them across any surface. Applying too
much pressure can break the retaining clips or damage the
socket slot. Apply only enough pressure on the retaining
clips to release the DIMM.
4.
Remove the DIMM modules one at a time starting from the highest
numbered sockets.
5. To remove each DIMM, gently spread the retaining levers (see Figure 4-7,
C) just enough so that you can pull the top edge of the DIMM away from the
levers.
6.
Carefully lift the DIMM away from the socket and store it in an antistatic
package.
7.
Repeat the above steps to remove the remaining DIMMs.
8. Hold the memory board by its edges and start to insert it into the slot guides.
On the baseboard, locate the memory board connector. Do not press in on
the board yet! Ease board into the slot guides until it is just touching the
connector on the baseboard.
9.
Be sure the ejector levers are extended so they can engage the chassis frame.
Press the board carefully but firmly into the baseboard connector to seat the
board. Close the ejectors on both sides of the memory board. Be sure the
ejector is firmly fastened in the chassis frame before closing the ejector.
10.
Fasten the right side of the support bracket into the chassis frame and swing
the support bracket into position so that the rear edge of the memory boards
fits snug against the bracket. The support bracket is secured to the chassis by
two fasteners. Push in on the support bracket fasteners until each clicks in
the locked position.
11.
Replace the right side panel and turn on the system.
