Chapter 2 Preparing to Service the System 2-9
Caution – Circuit boards and 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.
2.7.1.1 Using an Antistatic Wrist Strap
Wear an antistatic wrist strap and use an antistatic mat when handling components
such as 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 not included in the accessory kit for the Sun Fire
X4150 Server. However, antistatic wrist straps are still included with options.
2.7.1.2 Using an Antistatic Mat
Place ESD-sensitive components such as motherboards, memory, and other PCBs on
an antistatic mat.
2.7.2 ESD Handling Procedure
1. Prepare an antistatic surface to set parts on during the removal, installation, or
replacement process.
Place ESD-sensitive components such as the printed circuit boards on an antistatic
mat. The following items can be used as an antistatic mat:
■ Antistatic bag used to wrap a Sun replacement part
■ Sun ESD mat, part number 250-1088
■ A disposable ESD mat (shipped with some replacement parts or optional
system components)
