Removing and Replacing System
Boards and Assemblies
This chapter provides information on removing or replacing:
•
System boards
•
SuperSPARC modules
•
SBus cards
•
SIMMs and NVSIMMs
•
OpenBoot PROMs
•
TOD/NVRAM
Caution – The system chassis power must be turned OFF, and the AC power
cord must remain plugged in to ensure a proper ground.
Caution – The system board, its modules, and cards have surface-mount
components that can be broken by flexing the board.
To minimize the amount of board flexing, observe the following precautions:
•
Hold the system board only by the edges near the middle of the board,
where the board stiffener is located. Do not hold the board only at the ends.
•
When removing the board from an antistatic bag, keep the board vertical
until you lay it on the Sun ESD mat.
