When unpacking the board, make sure the person handling it is static protected.

Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the serverboard and the
chassis surface. The R424-E2 and R424-F2 chassis include permanent standoffs
in locations used by the serverboards. These standoffs accept the rounded Phillips
head screws included in the R424-E2 and R424-F2 accessories packaging.
Some serverboards require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are used for these serverboards.
To use an optional standoff, you must place a hexagon 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.
