If two control modules are installed in the array, but only one is shown in the GUI (or CLI), make
sure that you have allowed enough time (minimum of 5 minutes) for the two control modules to boot
and synchronize. When synchronization completes, a message appears on the serial console (if con-
nected), and the ACT LED on the secondary module is illuminated amber.
If the GUI (or CLI) still shows only one control module after appropriate time has elapsed, the con-
troller might not be properly installed. Try to remove the module by rotating the black lever and rein-
sert the module into the array chassis. Ensure that the face of the controller is even with the
controller already installed in the array.
After reinstalling the control module, if both control modules still do not appear in the GUI (or
CLI), contact your support provider.
After a control module is installed in an array, do not restart or reinstall it, or upgrade firm-

mary control module. This process occurs in the background and can take up to 45 minutes to complete,
depending on the control module type. To verify that the synchronization process has finished, you can
check for confirmation messages in the GUI event viewer or by using the CLI command
. If you interrupt the synchronization process, you might corrupt the control module's internal

firmware, and the control module will no longer function properly.
Replace the MicroSD Card
Each control module includes a microSD card that contains the PS Series firmware.
If a control module fails, you will need to remove the microSD card from the failed control module and
install the card in the replacement control module. Using the card from the failed control module
ensures that the new control module is running the same firmware and configuration as the other
control module in the array.
Before you begin the procedure to replace a microSD card:
