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.
