|
Note - The manufacturer and capacity of both modules in the same memory bank must be identical. |
5. Check the routing of all cables for obstructions, and then reinstall the cover.
The system battery is a common CR2032 calculator battery.
You might need to replace the system battery if you know it is weak or if after any period of AC power loss, the BIOS loses its CMOS settings, or if the time-of-day clock loses time.
|
Caution - Do not attempt to open or service batteries. The battery contains lithium and can explode if not properly used, handled, or disposed of. |
1. Power off the system and remove the cover as described in Section 4.3, Powering Off the Server and Removing the Cover.

|
Note - Replacement of a CPU and heatsink should only be done by trained service personnel. |
1. Power off the system and remove the cover as described in Section 4.3, Powering Off the Server and Removing the Cover.
2. Remove the air duct as shown in Section 4.5.6, Replacing an Air Duct.
3. Unfasten the four screws securing the heatsink to the board (see FIGURE 4-32).
|
Caution - The heatsink can become extremely hot. Be sure it has had sufficient time to cool before handling. |
4. Twist the heatsink slightly to the right or left to break the seal with the thermal grease.
5. Lift the heatsink away from the CPU.
6. Place the heatsink upside-down on a flat surface to prevent the thermal grease from contaminating other components.
7. Pull the socket release lever up to the fully open, perpendicular position.
9. Lift the CPU out of the socket, leaving the release lever in the open position.
|
Note - Ensure that no thermal grease that might be left from the heatsink comes into contact with the CPU socket or underside of the CPU chip. |
Follow these steps to install a CPU and heatsink if you are replacing a CPU.
|
Caution - Observe the appropriate ESD precautions in Section 4.2.1, ESD Precautionswhen handling the CPU. |
2. Ensure that the socket release lever is in the fully open, perpendicular position and the CPU cover is open (see FIGURE 4-34).
3. Align the small triangle, on the upper left corner of the CPU, with the triangle on the corner of the socket.
4. Insert the CPU into the socket.
5. When the CPU is fully seated in the socket, close the CPU cover.
The CPU cover might not align correctly with the chip, after it is installed. If this happens open the cover, and push it slightly to the side to better align it with the chip, and reclose the cover.
6. Rotate the socket release lever down until it snaps into place, securing the CPU in the socket.
7. Use the syringe to apply approximately 0.1 ML/CC of thermal grease in a circular pattern to the top of the CPU.
8. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.
9. Use an alcohol pad to remove all thermal grease from the bottom of the heatsink.
10. Inspect the heatsink for dust and lint. Clean if necessary.
11. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
|
Caution - If the heatsink is moved too much during its installation, the layer of thermal grease may become uneven, leading to component damage. |
12. Fasten the four screws attaching the heatsink to the motherboard. See FIGURE 4-35.
13. Replace the air duct. See Section 4.5.6, Replacing an Air Duct.
FIGURE 4-36 and FIGURE 4-37 shows the routing of the cables and motherboard connector locations.
