Chapter 2 Preparing to Service the System 2-9
Caution – Circuit boards, hard drives, and SSDs 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 without ESD precautions, especially along the
connector edges.
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
X4140 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)
2. Attach an antistatic wrist strap.
When servicing or removing server components, attach an antistatic strap to your
wrist and then to a metal area on the chassis.
