7 If the problem is not resolved, repeat step 2 and step 3. 8 Insert a known working USB key. 9 Install the system cover. Next step If the problem persists, see the Getting help section. Troubleshooting a micro SD card Prerequisite NOTE: Certain micro SD cards have a physical write-protect switch on the card. If the write-protect switch is turned on, the micro 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 micro SD card with a new micro 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 micro 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. Troubleshooting expansion cards 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: When troubleshooting an expansion card, you also have to see the documentation for your operating system and the expansion card. Steps 1 Run the appropriate diagnostic test. See the Using system diagnostics section. 2 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet. 3 Remove the system cover. 4 Ensure that each expansion card is firmly seated in its connector. 5 Install the system cover. 6 Turn on the system and attached peripherals. 7 If the problem is not resolved, turn off the system and attached peripherals, and disconnect the system from the electrical outlet. 8 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 micro SD card with a new micro 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
