Maintaining Control Module Firmware
A control module has a microSD card running the array firmware. You should run the latest firmware
version to take advantage of new product features and enhancements.
In a dual control module array, both control modules must be running the same firmware version;
otherwise, only one control module will be functional. You must update the controller with the older
version firmware to the same version as the active before you update the member to a later version.
Group members should run the same firmware version; otherwise, only the functionality common to all
versions will be available in the group. See the PS Series Release Notes for information about mixed-
firmware groups.
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 you keep the correct firmware. See
To display the firmware version running on an array, examine the GUI Member Controllers window or
use the following CLI command:
member select membername show controllers
If the firmware on a microSD card does not match the firmware running on an array, do not install it.
Instead, contact your array support provider.
Control Module Handling Requirements
Follow these control module handling requirements:
• Do not remove an active control module.
• Protect control modules from electrostatic discharge. Always wear an electrostatic wrist strap
when handling a control module. See
• Do not remove a control module from an array while the control modules are synchronizing. When
synchronization completes, a console message will appear. Also, the ACT LED on the secondary
control module will be orange.
• Do not leave a control module slot empty. In an array with one control module, always attach a
blank face plate to the empty control module slot.
• Store control modules properly. Store a control module in its original packaging or in an antistatic
bag or place the control module on a surface protected from electrostatic discharge.
About the Standby On/Off Button
The control module has a small, recessed button labeled STANDBY ON/OFF (see
button is recessed to prevent accidental activation.
