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

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.

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.
