5. Place the control module on a flat surface where it is protected from electrostatic charge. To avoid damage,
do not place anything on top of the control module.
6. If you are replacing a failed control module, remove the microSD card from the failed control module and
install it in the replacement control module. This ensures that the new control module runs the correct
firmware. See
Replacing the microSD Card on page 46
Caution:
Do not operate an array with an empty control module slot. If necessary, insert a controller blank as a
filler to maintain the correct airflow and cooling.
Return the failed control module in the packaging in which the replacement module was shipped. Contact your
PS Series support provider for information about returning hardware.
