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.
