4. If you are replacing a failed control module, remove the micro SD card from the failed control module as
described in Replacing the MicroSD Card on page 3-7 and install it in the replacement control module. This
will make sure that the new control module is running the correct firmware.
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 oriented horizontally in the array, with the label text right-side up (serial port to the left and
the Ethernet ports to the right), as shown in Figure 3-5.

To install a control module:
1. Attach an electrostatic wrist strap or a similar protective device. See Protecting Hardware from Electrostatic
Discharge on page 1-7.
2. Open the control module latches by squeezing together the release mechanism for each latch and then rotating
both latches outwards. See Figure 3-3.
3. Hold the latches and slide the control module into the slot until you feel resistance. See Figure 3-6.
