Damage Prevention

Caution – Use an antistatic mat when working with the system board. An antistatic
mat contains the amount of cushioning needed to protect the underside components,
to prevent board flexing, and to provide antistatic protection. Part numbers for
antistatic mats from Sun Microsystems are listed in Chapter 12.
10.2 Handling System Boards and
Assemblies
Caution – The system chassis power switch must be set to Standby, and the AC
power cord must remain plugged in to ensure a proper ground.
