How to Perform Factory Default using restore default button?A “Restore Default” button is a non-latch type push button accessed through a round opening underneath the Restore Default LED (See Figure 1). Please follow the instruction below.

1. Power OFF the controller.2. Use a straighten paper-clip to press the button.3. Press and hold the button down, power on the subsystem and wait for the associated LED and the

subsystem Read LED to light up.4. Once the factory defaults are successfully restored, the restore default LED lights green and then you can

release the button. Re-power cycle again.5. Once it complete, it will show “NVRAM Factory Default Restored”. Please see Figure 1 below. If you

didn’t see this message appear, please try again.

For redundant RAID controllers, the procedure can be tricky, please see below instruction:

1. Remove one controller from the subsystem, power down, and then power ON with the “Restore Default” button depressed to restore the firmware defaults on the remaining controller.2. Power down, install the controller previously removed, and repeat the restoration process.3. When completed with restoring default on both controllers, install both controllers and power ON.

Caution: Logical drive will remain intact after factory default restoration, configuration data such as LUN mapping and performance preference will be erased. Before using this button (factory default), make sure you have a written record or a previously saved configuration profile (one of the firmware functionalities, “save NVRAM”).

Please note that you will not be able to save the current configuration to disk, so any controller configuration settings will be changed back to their factory default values. This includes the IP address, Host Channel IDs, and any Host LUN mapping. DATA will not remove or destroy.
