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.
1. Remove the Sun Ultra 1 Model 200E Series motherboard from the upgrade
container and place the motherboard on the antistatic mat.
2. Remove filler panel(s) from the replacement system board so the rear
panel of the replacement system board and the old system board look the
same.
a. Squeeze the filler panel bottom locking tabs to unhook them from the
back panel (Figure 3-1).
b. Pull the filler panel away from the back panel.
