Troubleshooting an SD card

Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that are shipped with your product.
NOTE: Certain SD cards have a physical write-protect switch on the card. If the write-protect switch is turned on, the
SD card is not writable.
Steps
1. Enter System Setup, and ensure that the Internal SD Card Port is enabled.
2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3. Remove the system cover.
NOTE: When an SD card failure occurs, the internal dual SD module controller notifies the system. On the next
restart, the system displayed a message indicating the failure. If redundancy is enabled at the time of SD card
failure, a critical alert will be logged and chassis health will degrade.
4. Replace the failed SD card with a new SD card.
5. Install the system cover.
6. Reconnect the system to its electrical outlet and turn on the system, including any attached peripherals.
7. Enter System Setup, and ensure that the Internal SD Card Port and Internal SD Card Redundancy modes are set to the needed
modes.
Verify that the correct SD slot is set as Primary SD Card.
8. Check if the SD card is functioning properly.
9. If the Internal SD Card Redundancy option is set to Enabled at the time of the SD card failure, the system prompts you to perform
a rebuild.
NOTE: The rebuild is always sourced from the primary SD card to the secondary SD card.
