3. Place the control module on a flat surface where it will be protected from electrostatic charge. To avoid
damage, do not place anything on top of the control module.
4. 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 will make sure that the new control module is running the
correct firmware. See
Replacing the MicroSD Card on page 29 .
Caution: Do not operate an array with an empty control module slot.
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.
Installing a Control Module
You can install a control module without shutting down the array.
Caution: Do not mix control module types in an array.
Control modules are installed horizontally in the array, with the Ethernet ports on the left and the serial port on
the right.
Facing the rear of the array, the upper control module is CM0 and the lower control module is CM1, as shown in
the following illustration.
