Certain devices, such as such as the motherboard, PCI cards, and hard drives, are sensitive to electrostatic discharge (ESD). They require special handling.
The Sun Ultra 40 Workstation was designed to be serviced with the following tools:
See FIGURE 4-1.
Though not required for component replacement, the following tools have proven helpful in certain situations:
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:
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.
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.
