Hardware Owner's Manual 3 Maintaining Control Modules 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 five minutes) for the two control modules to boot and synchronize. When synchronization completes, a message will appear on the serial console (if connected), and the ACT LED on the secondary module will be orange. If the GUI (or CLI) still shows only one control module after appropriate time has elapsed, the control module may not be properly installed. In this case, reinstall the control module. After reinstalling the control module, if both control modules still do not appear in the GUI (or CLI), contact your support provider. Replacing the MicroSD Card Each control module includes a microSD card that contains the PS Series firmware. If a control module fails, you'll need to remove the microSD card from the failed control module and install the card in the replacement control module. This will make sure that the new control module is running the same firmware as the other control module in the array. Before you begin the procedure to replace a microSD card: • Review Replacing a Control Module on page 24 for information about removing and replacing a control mod- ule. • Attach an electrostatic wrist strap, as described in Protecting Hardware on page 2. MicroSD Card Replacement Procedure Use the following procedure for replacing the MicroSD card in your control module: 1. Remove the control module from the array. (As described in Removing a Control Module on page 26.) 2. Remove the SD card from the control module. (As described in Removing the MicroSD Card on page 29.) 3. Install the replacement SD card in the control module. (As described in Inserting the MicroSD Card on page 30.) 4. Insert the control module into the array. (As described in Installing a Control Module on page 27.) Removing the MicroSD Card Caution: To reduce the risk of losing or damaging the microSD card, do not remove it until you are ready to install it in the replacement control module. 29

Hardware Owner's Manual
3 Maintaining Control Modules
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 five minutes) for the two control modules to boot and syn-
chronize. When synchronization completes, a message will appear on the serial console (if connected), and
the ACT LED on the secondary module will be orange.
If the GUI (or CLI) still shows only one control module
after appropriate time has elapsed, the control mod-
ule may not be properly installed. In this case, reinstall the control module.
After reinstalling the control module, if both control modules
still do not appear in the GUI (or CLI), contact
your support provider.
Replacing the MicroSD Card
Each control module includes a microSD card that contains the PS Series firmware.
If a control module fails, you'll need to remove the microSD card from the failed control module and install the
card in the replacement control module. This will make sure that the new control module is running the same
firmware as the other control module in the array.
Before you begin the procedure to replace a microSD card:
•
Review
