Esd Measures; Antistatic Wrist Strap Use; Antistatic Mat - Sun Oracle SPARC T3-2 Service Manual

ESD Measures

Electrostatic discharge (ESD) sensitive devices, such as the Flash Modules, PCI cards,
hard disk drives, and DIMMS, require special handling.
Caution – Circuit boards and hard disk 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 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 this
server. However, antistatic wrist straps are still included with options.

Antistatic Mat

Place ESD-sensitive components such as motherboards, memory, and other PCBs on
an antistatic mat.
