Electrostatic discharge (ESD)-sensitive devices, such as the motherboard, PCI cards, hard drives, and the NVRAM, require special handling.
Use the following tools to service the Sun Ultra 45 or Ultra 25 workstations (FIGURE 2-1):
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, hard drives, and the NVRAM on an antistatic mat. The following items can be used as an antistatic mat:
1. Notify any affected users that the system will be powered down.
2. Save any open files and quit all applications.
3. Press and release the Power button or the Sleep key (FIGURE 2-2).
If you pressed the Sleep key, select "Shutdown," from the menu.
4. Power off and disconnect any peripherals (FIGURE 2-3).
5. Disconnect the keyboard, mouse, monitor, and network connections.
1. Press down the two latches on the side cover and lift the cover off the workstation (FIGURE 2-4).
2. Using both hands, place the workstation on its side.
3. Pivot the workstation support stabilizer underneath the workstation.
4. 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.
a. Slide the lock block towards the front of the system.
b. Press and release the two latches and lift the access panel.
6. Disconnect the power cord from the workstation.
7. If necessary, remove any long PCI cards and pull the fan tray out of the chassis.
8. Find your removal or replacement procedure (TABLE 2-1).
Identify the component that you need to replace in FIGURE 2-5 and refer to TABLE 2-1 to find the replacement procedure.
