Force a down and rearward pressure to move the chassis lid backward by about
1/4”. The lid will make a snapping sound after it travels fully toward the chassis
rear. This requires moderate force.
With your palms on the chassis lid, curl your fingers around the chassis edge and
place them against the fan module. In this position you can press downward on
the chassis lid and pull the lid toward the rear in one motion.

Set the lid aside.
SSM Installation
Once the Net-Net 4250 SD chassis is open, SSM installation is straightforward. The
SSM attaches electrically to the Net-Net 4250 SD motherboard by three board-to-
board connectors. In addition, it is secured to the motherboard by four screws.
Caution
Before handling the SSM, ground yourself using an ESD wrist
strap or other comparable grounding system. Failure to do so
could damage the SSM or the Net-Net 4250 SD chassis.
