For your protection, observe the following safety precautions when setting up your equipment:
Follow all cautions and instructions marked on the equipment and described in the documentation shipped with your system.
Follow all cautions and instructions marked on the equipment and described in the Sun SPARC Enterprise T5140 and T5240 Servers Safety and Compliance Guide.
Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment’s electrical rating label.
Follow the electrostatic discharge safety practices as described in this section.
You will see the following symbols in various places in the server documentation. Note the explanations provided next to each symbol.
Caution - There is a risk of personal injury or 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.
Caution - Circuit 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 the components located on these boards. Do not touch the components along their connector edges.
Caution - You must disconnect both power supplies before servicing any of the components documented in this chapter.
Wear an antistatic wrist strap and use an antistatic mat when handling components such as hard drive assemblies, circuit boards, or PCI cards. When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Following this practice equalizes the electrical potentials between you and the server.
Note - An antistatic wrist strap is no longer included in the accessory kit for the Sun SPARC Enterprise T5140 and T5240 servers. However, antistatic wrist straps are still included with options.
Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.
