Safety Symbols
Note the meanings of the following symbols that might appear in this document:
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.
ESD Measures
ESD-sensitive devices, such as networking adapters, hard drives, and DIMMs require special
handling.
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 all power supplies before servicing any of the components that
are inside the chassis.
Antistatic Wrist Strap Use
Wear an antistatic wrist strap, and use an antistatic mat when you are handling components such
as hard drive assemblies, circuit boards, or networking adapters. 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.
Antistatic Mat
Place ESD-sensitive components such as motherboards, memory, and other PCBs on an
antistatic mat.
