Compaq Technician Notes WARNING: To reduce the risk of personal injury from electrical shock and hazardous energy levels, do not exceed the level of repair specified in these procedures. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or make modifications to any printed wiring board. Improper repairs could create conditions that are hazardous. WARNING: To reduce the risk of electric shock or damage to the equipment: Disconnect power from the computer by unplugging the power cord from either the electrical outlet or the computer. Do not disable the power cord grounding plug. The grounding plug is an important safety feature. Plug the AC adapter or power cord into a grounded (earthed) electrical outlet that is easily accessible at all times. CAUTION: To properly ventilate the system, you must provide at least 6 inches (15 cm) of clearance at the front of the workstation and 3 inches (7.6 cm) at the back. IMPORTANT: Any indication of repair at the component level or modification of a printed wiring board may void any warranty. Compaq Professional Workstation AP500 Maintenance and Service Guide 2-2 Service Preliminaries Preliminary Warnings and Cautions The following should be noted when operating or servicing the Compaq Professional Workstation AP500: WARNING: To reduce the risk of electric shock or damage to the equipment: ¦ Disconnect power from the system by unplugging all power cords from either the electrical outlet or the Compaq Professional Workstation AP500. ¦ Do not disable the power cord grounding plug. The ground plug is an important safety feature. ¦ Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times. WARNING: To reduce the risk of personal injury from hazardous energy levels, only authorized service technicians should attempt to repair this equipment. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. CAUTION: The power supply in the Compaq Professional Workstation AP500 has an auxiliary power section. This section is always active as long as the unit is plugged into a live AC outlet. Be sure to turn off the switch and unplug the power cord before performing any service work. CAUTION: To properly ventilate the system, you must provide at least 6 inches (15 cm) of clearance at the front of the workstation and 3 inches (7.6 cm) at the back. IMPORTANT: Any indications of component replacement or printed wiring board modifications may void any warranty. 2-3 Electrostatic Discharge Information A discharge of static electricity can damage static-sensitive devices or micro-circuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions: ¦ Transport products in static-safe containers (conductive tubes, bags, or boxes). ¦ Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations. ¦ Cover workstations with approved static-dissipating material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ¦ Keep work area free of non-conductive materials such as ordinary plastic assembly aids and foam packing. ¦ Be sure you are always properly grounded when touching a static-sensitive component or assembly. ¦ Avoid touching pins, leads, or circuitry. ¦ Always place drives PCB assembly-side down. ¦ Use conductive field service tools. Equipment Symbols The following symbols are located on applicable components of the workstation and should be observed when servicing the workstation to avoid personal injury or damage to the components: WARNING: Any surface or area of the equipment marked with these symbols indicates the presence of a hot surface or hot component. If this surface is contacted, the potential for injury exists. To reduce risk of injury from a hot component, allow the surface to cool before touching. WARNING: Any surface or area of the equipment marked with these symbols indicates the presence of electrical shock hazards. Enclosed area contains no operator serviceable parts. To reduce risk of injury from electrical shock hazards, do not open this enclosure. WARNING: Any RJ-45 receptacle marked with these symbols indicates a Network Interface Connection. To reduce risk of electrical shock, fire, or damage to the equipment, do not plug telephone or telecommunications connectors into this receptacle.
