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.

system. On the next restart, the system displays a message indicating the failure. If redundancy
is enabled at the time of SD card failure, a critical alert is logged and chassis health degrades.
4. Replace the failed SD card with a new SD card.

8. Check if the SD card is functioning properly.
