SC825M(B) Chassis Manual

Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and the
chassis surface. The SC825M(B) chassis includes permanent standoffs in locations
used by most motherboards.
Some motherboards require additional screws for certain CPUs, heatsinks, and
other components. Optional standoffs are included for these motherboards. To use
an optional standoff, screw the standoff into the chassis in the same manner as
the permanent standoffs.
Installing the Motherboard:
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, precautions, and cable connections.
2. Power down the system and remove the power cord from the back of the
power supply module as described in Section 5-2. Remove the chassis cover
as described in Section 5-3.
3. As required by your motherboard, install standoffs in any areas that do not have
a permanent standoff. All motherboard mounting holes should have matching
chassis standoffs. If there are additional standoffs in the chassis that are not
used by the motherboard, remove them. DO NOT allow extra standoffs to remain
in the chassis that are not used by the motherboard.
4. Place the motherboard in the chassis aligning the permanent and optional
standoffs. In addition, make sure the motherboard aligns with the I/O shield.
5. Secure the motherboard to the chassis using the rounded, Phillips head screws.
6. Secure the CPUs, heatsinks, and other components to the motherboard as
described in the motherboard documentation.
7. Connect the cables between the motherboard, backplane, chassis, front panel,
and power supply, as needed. Also, the fans may be temporarily removed to
allow access to the backplane ports.
