System Board

To remove and replace a system board, proceed as follows.
Caution – Use an antistatic mat when working with the system board. An antistatic
!
mat contains the cushioning needed to protect the underside components, to prevent
board flexing, and to provide antistatic protection.
Note – If the system board is being replaced, remove all DSIMMs, FFB card, and
SBus card(s) prior to removing the system board. Note the chassis slot location for
each DSIMM, FFB card, and SBus card prior to removal.
