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

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 writeable.
Steps
1. Enter the 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 reboot, the system displays 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.
