Replacing Both Control Modules
Use the following procedure to replace both control modules in the array:
1. Replace the secondary control module first, as described in Replacing the Secondary Control
Module on page 21.
2. Remove and swap the battery from the existing control module to the replacement control module,
as described in Battery Replacement on page 27.

Remove a Control Module
Before removing a control module:
• Review the information at the beginning of Replace a Control Module on page 21.
• Attach an electrostatic wrist strap. See Hardware Protection on page 6.
• 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.
Caution: Do not remove an active control module.
To remove a control module:
1. Push down on the orange release button (callout 2 in Figure 14).
2. While holding down the orange button, swing the black release latch toward you. Swinging the
latch starts to eject the control module (callout 1) from the array. Remove the control module.
