I/O Shield
The I/O shield holds the serverboard ports in place. The I/O shield does not require
installation, however, the serverboard must match up with the I/O shield (Figure 6-9).

Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the serverboard and
the chassis surface. The SC808 chassis includes permanent standoffs in locations
used by the serverboards. These standoffs accept the rounded Phillips head screws
included in the SC808 accessories packaging.
Some serverboards require additional screws for heatsinks, general components
and for stability. Optional standoffs are used for these serverboards.
To use an optional standoff, you must place a hexagonal screw through the bottom
the chassis and secure the screw with the hexagonal nut (rounded side up).
Depending upon the confi guration of the serverboard being used, it is also possible
that some of the optional standoffs which are pre-installed in the chassis, may need
to be removed.
Installing the Serverboard (Figure 6-10)
1. Review the documentation that came with your serverboard. Become
familiar with component placement, requirements, precautions, and cable
connections.
2. Disconnect the chassis from any power source and open the chassis cover.
3. Remove the expansion card brackets. To do this:
A. Remove screw securing the expansion card bracket to the chassis.
B. Lift the bracket out of the chassis.
C. Repeat this process for the second riser card.
4. Lay the fi rst serverboard in the chassis aligning the standoffs
