danger to personal health, follow the instructions.

Electrostatic Discharge Safety Measures

Electrostatic discharge (ESD) sensitive devices, such as the motherboards, PCI cards,
hard drives, and memory cards 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 both power supplies before servicing any of the

components documented in this chapter.

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 the

SPARC Enterprise T5120 and T5220 servers. However, antistatic wrist straps are still
included with options.
