Motherboard Securing
Remove the extended expansion card guide before installing or removing
the motherboard. All screws are necessary to provide the needed stabiliza-
tion to support all the motherboard expansion cards used in a server.
Place four spacers in the ar-
eas circled on the chassis.
Installed motherboard
Place twelve screws in the areas
circled on the motherboard.
There is a chassis intrusion con-
nector here.
The chassis provides an micro toggle
switch that must be connected to the
motherboard for the chassis intrusion
detection to work. The motherboard
will signal the ASMA software when
the side panel is opened. The connec-
tion diagram is given here.
