Maintaining the Workstation |
This chapter provides instructions on how to add, replace, and configure the components in the Sun Ultra 20 M2 Workstation after it is set up. The following sections are included in this chapter:
The following procedures are for replacing customer-replaceable units (CRUs):
The following procedures should only be performed by trained field service technicians:
Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component:
|
Caution - Do not operate the workstation for more than ten minutes when the left side access panel is removed. Improper cooling airflow might damage the system's components. |
This section describes how to remove the left side access panel and the front bezel.
Before you remove, replace, or install any components, perform the following steps.
1. Power off the system and all of the peripherals connected to it.
2. Turn the power switch on the back of the chassis to the Off position ( 0 ).
|
Caution - Failure to properly turn off the system before you start installing components can cause serious component damage. |
3. To maintain system grounding, do not unplug the AC power cord from the back of the system unless the specific procedure instructs you to unplug it.
4. Loosen the two captive thumbscrews located on the rear edge of the left side access panel (see FIGURE 5-1).
5. Slide the access panel approximately 1.5 cm toward the back of the workstation.
6. Tilt the top edge of the panel out, then lift the panel upward.
7. Carefully set the panel aside.
|
Note - Do not remove the front bezel unless removal is required to complete the current maintenance procedure. |
Follow these instructions to remove the front bezel.
1. Perform the steps listed in Section 5.2.2, Powering Off the System and Removing the Left Side Access Panel.
2. Loosen the two left side bezel tabs (see FIGURE 5-2) by gently pressing the side of each tab inward and slightly forward.
The edge of the bezel nearest the tabs moves slightly away from the front of the chassis as the ridges holding each tab in place are released.
|
Caution - Be very careful when pulling the bezel away from the chassis. The bezel tabs and the chassis hooks might break if you apply too much force or attempt to swing the bezel open. |
3. Gently move the left-front side of the bezel slightly to the left, then forward to disengage the three chassis hooks on the right side (see FIGURE 5-2).
4. Remove the bezel and set it aside.
This section describes how to install the left side access panel and the front bezel.
Perform the following steps after installing a workstation component.
1. Ensure that all the components are installed as described in the step-by-step instructions.
2. Reinstall any PCI cards, PCI-E cards, or peripherals that you removed.

1. Insert the right side bezel hooks into the right side chassis slots. See FIGURE 5-3.
2. Insert the left side bezel tabs into the chassis slots, and gently press the left side of the bezel toward the chassis until the tabs lock.
|
Caution - Use care when installing the bezel. The bezel tabs and the chassis hooks might break if you apply too much force or attempt to swing the bezel closed. |
Install the left side access panel after you finish inspecting or installing components.
1. Ensure that all of the components are installed as described in the step-by-step instructions for the procedure you are following.
2. Reinstall any PCI cards, PCI-E cards, or peripherals that you removed.
4. Position the access panel so the lip on the inside bottom of the panel fits over the bottom chassis rail.
5. Pressing gently against the top of the access panel, slide the panel toward the front of the chassis. See FIGURE 5-4.
The access panel lies flat against the chassis, with no gaps between the two.
6. Tighten the two captive thumbscrews located on the rear lip of the panel.
The access panel is installed flat against the chassis with the thumbscrews tightened.

|
Note - Before removing the CPU from the motherboard, create a backup file to preserve all important data. |
1. Follow the steps in Section 5.2.2, Powering Off the System and Removing the Left Side Access Panel.
2. Gently lay the system on its right side on a stable, nonslip surface.
|
Caution - The heatsink can become extremely hot. Allow a few minutes for the heatsink to cool before attempting this procedure. |
3. Disconnect the CPU fan cable from its connector on the motherboard.
4. Pull up the lever on the right side of the heatsink/fan assembly to loosen the metal latch from the hook on the retaining bracket (see FIGURE 5-31).
5. Push down the metal latch on the left side of the assembly to loosen the latch from the hook on the retaining bracket (see FIGURE 5-31).
6. Twist the heatsink/fan assembly to the right or the left, in order to break the seal with the thermal grease.
7. Lift the heatsink/fan assembly straight up and withdraw it from the board (see FIGURE 5-32).
8. Place the heatsink upside down on a flat surface to prevent the thermal grease from contaminating other components.
9. Depress, and then pull up the CPU socket retainer lever up to the fully open position (see FIGURE 5-33).
10. Lift the CPU out of the socket, leaving the retainer lever in the open position.
11. Install the heatsink and CPU as shown in Section 5.16.2, Installing a Heatsink and CPU.
Perform this procedure to install the heatsink and CPU.
|
Note - Observe the ESD precautions and preinstallation procedures described in Section 5.1, Electrostatic Discharge (ESD) Precautions. |
1. Ensure that the CPU socket retainer lever is in the fully open position. See FIGURE 5-34.
2. Align the CPU to its socket so that pin 1 of the CPU (indicated by the notched corner) is aligned with hole 1 of the socket (indicated by the arrow in the corner of the socket).

|
Note - When correctly aligned, the CPU should drop effortlessly into the socket. Do not attempt to force the CPU into the socket to seat it. |
4. When the CPU is positioned in the socket, press down on the socket retainer lever to lock the CPU in place.
5. Do this step only if you are installing a new CPU. Otherwise, go to Step 6.
a. Clean any contamination from the top of surface of the CPU, using the supplied alcohol wipe.
The heatsink assembly already has thermal grease applied. You do not need to apply additional thermal grease.
b. Remove the plastic cover from the heatsink/fan assembly.
6. Do this step if you are installing an already-used CPU onto a new motherboard. Otherwise, go to Step 7.
a. Remove the grease from the CPU and remove the thermal interface material from the heatsink using the alcohol wipe supplied with the motherboard.
b. Use the syringe that is supplied with the motherboard to apply approximately 0.5 ml of thermal grease to the center of the top of the CPU.
Empty the entire syringe onto the chip.
c. Using the wrapper of the alcohol wipe or a finger inserted into a clean plastic bag, spread out the thermal grease to a thin, uniform thickness over the CPU.
|
Caution - Do not use an unprotected finger to spread the thermal grease. The oil on your finger will degrade the performance of the thermal grease. |
7. Inspect the heatsink/fan assembly for dust and lint. Clean if necessary.
8. Carefully position the heatsink/fan assembly on the CPU, aligning it with the mounting hooks to reduce movement after it makes initial contact with the layer of thermal grease. See FIGURE 5-35.
|
Caution - If you move the heatsink assembly too much during installation, the layer of thermal grease might not be distributed evenly, leading to component damage. |
