4.1 Safety Information

This section provides safety precautions to follow when servicing the Sun Ultra 40 Workstation.

4.1.1 Safety Precautions

For your protection, observe the following safety precautions when setting up your equipment:

• Follow all Sun standard cautions, warnings, and instructions marked on the equipment and described in Important Safety Information for Sun Hardware Systems, part number 816-7190.
• Follow the cautions, warnings, and instructions in the Ultra 40 and Ultra 40 M2 Safety and Compliance Guide, part number 820-0122. The document is available at:

http://www.sun.com/documentation/

• Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment’s electrical rating label.
• Never push objects of any kind through openings in the equipment. Dangerous voltages might be present. Conductive foreign objects could produce a short circuit that could cause fire, electric shock, or damage to your equipment.

4.1.2 Safety Symbols

The following symbols might appear in this book. Please note their meanings:

Caution - There is a risk of personal injury and equipment damage. To avoid personal injury and equipment damage, follow the instructions.

Caution - Hot surface. Avoid contact. Surfaces are hot and might cause personal injury if touched.

Caution - Hazardous voltages are present. To reduce the risk of electric shock and danger to personal health, follow the instructions.

4.1.3 Electrostatic Discharge Safety

Certain devices, such as such as the motherboard, PCI cards, and hard drives, are sensitive to electrostatic discharge (ESD). They require special handling.

Caution - The boards and hard drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy components. Do not touch the components along their connector edges. Wear an antistatic wrist strap and use an antistatic mat when handling components such as drive assemblies, boards, or DIMMs. When servicing or removing workstation components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Then disconnect the power cord from the workstation and the wall receptacle. Following this caution equalizes all electrical potentials with the workstation.

4.2 Required Tools

The Sun Ultra 40 Workstation was designed to be serviced with the following tools:

• No. 2 Phillips screwdriver
• Antistatic wrist strap
• Antistatic mat
• Container for screws

See FIGURE 4-1.

FIGURE 4-1 Required Tools

Though not required for component replacement, the following tools have proven helpful in certain situations:

• Needle nose pliers, tweezers, or hemostat
• Large jeweler’s screwdriver
• Flashlight

Place ESD-sensitive components such as the motherboard, memory, PCI cards, and hard drives on an antistatic mat. The following items can be used as an antistatic mat:

• Antistatic bag used to wrap a Sun replacement part
• Sun ESD mat, part number 250-1088 (available through your Sun sales representative)
• Disposable ESD mat (might be shipped with replacement parts or optional system components)

4.3 Preparing the Workstation for Servicing

To prepare the workstation for servicing:

1. Power off the workstation as described in Section 1.4.2, Powering Off the Workstation.

See FIGURE 4-2 for the location of the power button.

2. Power off and disconnect the monitor, keyboard, mouse, network connections, and any peripherals.

3. Disconnect the power cord from the workstation.

See FIGURE 4-3.

4. Press down the two latches on the side cover and lift the cover off the workstation.

See FIGURE 4-4, part 1 for Step 4 through Step 9.

5. Using both hands, place the workstation on its side.

See FIGURE 4-4, part 2.

6. Pivot the workstation support leg underneath the workstation.

See FIGURE 4-4, part 2.

7. Remove the access panel:

a. Slide the lock block to the front of the system.

b. Press and release the two latches and lift the access panel.

See FIGURE 4-4, part 4.

8. Attach the antistatic wrist strap.

Wrap the adhesive portion around your wrist. Attach the copper end to the rear vent of the chassis. Ensure that the location does not interfere with your service procedure.

See FIGURE 4-4, part 5.

9. If your procedure requires it, lift the fan module up and out.

Grasp it by the handle and slide it straight up.

See FIGURE 4-4, part 5.

10. Find the removal or replacement procedure you need.

See TABLE 4-1.
