This chapter contains the following sections:
To determine and isolate a faulty component, refer to Section , Performing Diagnostics.
You need the following tools and supplies for performing Sun Fire X2250 server maintenance procedures.
Before removing the system’s top cover, read the following sections. These sections contain important electrostatic discharge (ESD) precautions, along with preinstallation and postinstallation instructions.
ESD can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component.
Always perform the following steps before you install any component:
1. Turn off the system and all of the peripherals connected to it.
|
Caution - Failure to properly turn off the system before you start installing components can cause serious component damage. |
|
|
Caution - Follow the ESD precautions described in Section 4.2.1, ESD Precautionswhen handling a system component. |
See Section 4.3, Powering Off the Server and Removing the Cover for the appropriate procedure for removing the cover from the server.
Perform the following steps after installing a server component.
1. Ensure that all of the components are installed as described in the component replacement instructions.
See Section 4.5, Component Replacement Procedures.
2. Reinstall any PCI-Express (PCIe) cards or peripherals that you had previously removed.
See Section 4.5, Component Replacement Procedures.
3. Reinstall the system’s cover.
See Section 4.3, Powering Off the Server and Removing the Cover.

The following procedure describes how to replace a CPU. The Sun Fire X2250 server supports both single-CPU and dual-CPU configurations.
| Note - Replacement of a CPU and heatsink should only be done by trained service personnel. If you are adding a second CPU to a single CPU configuration, see Section 4.5.13, Installing a New CPU. |
|
|
Caution - Observe the appropriate ESD precautions in Section 4.2.1, ESD Precautionswhen handling the CPU. |
1. Power off the system and remove the cover as described in Section 4.3, Powering Off the Server and Removing the Cover.
2. Unfasten the four screws securing the heatsink to the board (see FIGURE 4-32).
FIGURE 4-32 Removing a Heatsink
|
Caution - The heatsink can become extremely hot. Be sure it has had sufficient time to cool before handling. |
3. Twist the heatsink slightly to the right or left to break the seal with the thermal grease.
4. Lift the heatsink away from the CPU.
5. Place the heatsink upside-down on a flat surface to prevent the thermal grease from contaminating other components.
6. Pull the socket release lever up to the fully open, perpendicular position.
8. 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. If you want to install a new CPU or install a second CPU into a formerly single-CPU system, see Section 4.5.13, Installing a New 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.
FIGURE 4-34 Installing the CPU
4. Insert the CPU into the socket.
5. When the CPU is fully seated in the socket, close the CPU cover.
6. Rotate the socket release lever down until it snaps into place, securing the CPU in the socket.
7. Use the entire syringe contents to apply thermal grease in a circular pattern to the top of the CPU.
| Note - If you are replacing an existing heatsink with a new heatsink, you do not need to use the syringe to add additional thermal grease to the heatsink, as new heatsinks are pre-greased. |
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. Alternate between the four screws, turning each screw two turns until all are securely fastened. See FIGURE 4-35.
FIGURE 4-35 Installing the Heatsink
| Note - Replacement of a CPU and heatsink should only be done by trained service personnel. If you are replacing an already installed CPU, rather than adding a new one, follow the instructions in Section 4.5.12, Replacing a CPU and Heatsink. |
|
|
Caution - Observe the appropriate ESD precautions in Section 4.2.1, ESD Precautionswhen handling the CPU. |
To install a new CPU and heatsink:
