3 Maintaining Control Modules
2. Remove and swap the battery from the existing control module to the replacement control module, as
described in Battery Replacement on page 26.
3. Use the restart command to make the active control module secondary.
4. Replace the control module that is now secondary (was active before the restart), as described in Replacing
the Secondary Control Module on page 21.
Removing a Control Module
Before removing a control module:
• Review the information at the beginning of Replacing a Control Module on page 20.
• Attach an electrostatic wrist strap. See Protecting Hardware on page 1.
• Disconnect any serial or network cables attached to the control module. If the other control module has open
interface connectors, reattach the network cables to the other control module to provide uninterrupted data
access.
Do not remove an active control module.
To remove a control module:
1. Push down on the orange release button (callout 1 in Figure 17).
2. While holding down the orange button (callout 1), swing the black release latch (callout 2) toward you.
Swinging the latch starts to eject the control module from the array. Remove the control module.

3. Place the control module on a flat surface where it will be protected from electrostatic discharge. 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. Using the card from the failed control module ensures that the
new control module is running the correct firmware and a correct array configuration. See Replacing the
MicroSD Card on page 24.
