Precautions
Caution –
The system chassis power must be turned off, and the AC power cord
must remain plugged in to ensure a proper ground.
To minimize electrostatic discharge, observe the following precautions:
■
Hold the system board, SBus cards, DSIMMs, or system components only by the
edges.
■
When removing a board, card, or module from an antistatic bag, lay it on an
antistatic surface such as a Sun ESD mat, an antistatic bag, or a disposable
antistatic mat.
■
Do not place the boards, cards, or modules on an unprotected surface. Use a
cushioned antistatic mat or antistatic bag. Connectors and components have very
thin pins that bend easily.
■
Do not use an oscilloscope or VOM (volt-ohmmeter) probe on the components.
The soldered pins are easily damaged or shorted by the probe point.
■
Transport boards, cards, or modules in an antistatic bag.
■
Always wear an antistatic wrist strap connected to a metal surface on the chassis
when working on system components and parts.
