2-2 Sun Netra T5220 Server Service Manual • January 2012
Caution – There is a risk of personal injury and 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.
2.1.2 Electrostatic Discharge Safety
Electrostatic discharge (ESD) sensitive devices, such as the motherboard, PCI cards,
hard drives, and memory cards require special handling.
Caution – The 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 components. Do not touch the
components along their connector edges.
2.1.2.1 Use an Antistatic Wrist Strap
Wear an antistatic wrist strap and use an antistatic mat when handling components
such as drive assemblies, boards, or cards. When servicing or removing server
components, attach an antistatic strap to your wrist and then to a metal area on the
chassis. Then disconnect the power cords from the server. Following this practice
equalizes the electrical potentials between you and the server.
2.1.2.2 Use an Antistatic Mat
Place ESD-sensitive components such as the motherboard, memory, and other PCB
cards on an antistatic mat.
