To display the firmware version running on an array, examine the GUI Member Controllers window, the
CMC Array Status page, or execute this CLI command:
member select 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.
•
Do not remove a control module from an array while the control modules are synchronizing.
When syn-
chronization completes, a console message will appear. Also, the ACT LED on the secondary control mod-
ule will be orange.
• Do not leave a control module slot empty. In an array with one control module, insert a filler, a controller
blank, into the empty control module slot to maintain correct air flow and cooling.
• Protect control modules from electrostatic discharge. Always wear an electrostatic wrist strap when han-
dling a control module, as described in Protecting Hardware on page 6 .
• Store control modules properly. Store a control module in its original packaging or in an anti-static bag or
place the control module on a surface protected from electrostatic discharge.
Replacing a Control Module
If a control module fails, remove it and replace it with a functioning control module, as described in this section.
You will also need to temporarily remove a control module when you want to replace its microSD card. Refer to
Replacing the microSD Card on page 46
for information about replacing the microSD card.
You can partially or completely remove a control module without shutting down the array if the remaining
control module has at least one connected and functioning network interface. The procedures for doing this type
of control module replacement are described in
Control Module Replacement Procedures on page 40 .
When you remove a control module, wear an electrostatic wrist strap, as described in Protecting Hardware on
page 6 , and be sure to place it on a surface that is protected from electrostatic discharge.
Control Module Cautions :
• Do not remove an active control module.
• Do not remove a control module from an array while the control modules are synchronizing. A message
will appear on the console when synchronization completes. The ACT LED on the secondary control
module will be orange when synchronization is complete.
