Disposable wrist strap
Electrostatic Discharge Precautions
Caution: Circuit board components are vulnerable to damage by electrostatic discharge (ESD). An
electrostatic charge can build up on the human body and then discharge when you touch a board. Such
discharge can be produced by walking across a carpet and touching a board, or by other similar causes.
Before handling any board, make sure you dissipate your body’s charge. Touch a conductive surface of the
chassis or other element connected to common earth ground to discharge the static electricity present in your
body. To minimize risk of ESD damage:
Handle board by edges only
Store board in antistatic bag provided
1.3 Using the Disposable Wrist Strap
The wrist strap is a device that provides grounding for static electricity between your body and the system
unit chassis. Electric current and voltage do not pass through the wrist strap. When needed, attach the wrist
strap to your wrist and to the metal case or the power supply. Parts that require the use of a wrist strap are
packed with one.
Caution: Boards and modules can be damaged by harmful electrical charges if you do not wear a wrist strap.
To attach wrist strap:
1. Wrap the grounding strap with the conductive adhesive tape twice around your wrist.
Make sure the adhesive tape is against your skin.

2. Attach the end with the adhesive copper strip to the metal casing of the power supply in the system
unit.
Note: For SPARCserver 600MP systems, use ESD kit P/N 250-1088 (or equivalent). Instructions are
supplied with the kit.
