Control Module Replacement Procedures
This section describes the procedures for removing and replacing one or both control modules in your
PS Series array. The following replacement scenarios are covered:
• Replacing the secondary control module in an array
• Replacing the active control module in an array
• Replacing both control modules in an array
Replacing the Secondary Control Module
If the array is fully powered up and functioning, use the following procedure to replace the secondary
control module in the array:
1. Remove the control module from the array, as described in Removing a Control Module on page 21.
2. Remove the SD card from the control module, as described in Removing the MicroSD Card on
page 24.
3. Install the SD card in the replacement control module, as described in Inserting the MicroSD Card
on page 25.
4. Insert the replacement control module into the array, as described in Installing a Control Module on

Replacing the Active Control Module
Use the following procedure to replace the active control module in the array:
3. Use the restart command to make the active control module secondary.
4. Install the SD card in the replacement control module.
5. Replace the control module that is now secondary (was active before the restart), as described in
Replacing the Secondary Control Module on page 21.
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. Use the restart command to make the active control module secondary.
