Replacing The SD Card

NOTE: The SD card in the lower card slot is the primary card (SD1) and the SD card in the upper card slot is the secondary card (SD2).

Enter the System Setup and ensure that the Internal SD Card Port is enabled.
- CAUTION: If the Internal SD Card Redundancy option is set to Mirror Mode in the Integrated Devices screen of the system setup, you must follow the instructions in step 4 through step 6 to avoid loss of data.
- NOTE: When an SD card failure occurs, the Internal SD Card Redundancy option in the System Setup is set to disabled and the internal dual SD module controller notifies the system. On the next reboot, the system displays a message indicating the failure.
Remove the blade from the enclosure.
If the Internal SD Card Redundancy option is set to Disabled, replace the failed SD card with a new SD card.
Install the blade in the enclosure.
Enter the System Setup and ensure that the Internal SD Card Port and Internal SD Card Redundancy mode is enabled.
Check if the new SD card is functioning properly. If the problem persists, see Getting Help.
