Owners Manual

Internal dual SD module (optional)
The Internal Dual SD module (IDSDM) provides you with a redundant SD card solution. You can configure the IDSDM for storage
or as the OS boot partition. In modular servers, you can choose either a redundant SD module mode or share one slot with the
iDRAC module and the remaining slot can be used for storage or as the OS partition.
The Internal Dual SD Module (IDSDM) card provides two SD card slots and a USB interface dedicated for the embedded
hypervisor. This card offers the following features:
● Dual card operation—maintains a mirrored configuration by using SD cards in both slots and provides redundancy.
● Single card operation—single card operation is supported, but without redundancy.
Replacing an SD card
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.
1. Follow the safety guidelines listed in safety instructions section.
2. Follow the procedure listed in the Before working inside your system section.
3. Enter the System Setup and ensure that the Internal SD Card Port is enabled.
CAUTION:
When an SD card failure occurs, and the Internal SD Card Redundancy option in the Integrated
Devices screen of the System Setup is set to Mirror Mode, there may be loss of data. To avoid data loss, follow
step 4 through step 6 of the Troubleshooting an internal SD card section.
NOTE: The SD card in the lower card slot is the primary card (SD1) and the SD card in the upper card slot is the secondary
card (SD2).
NOTE: When an SD card failure occurs, the Internal SD Card Redundancy option in the System Setup is set to Disabled
and the internal dual SD module controller notifies the system. On the next reboot, the system displays a message indicating
the failure.
NOTE: If the Internal SD Card Redundancy option is set to Disabled, replace the failed SD card with a new SD card.
1. Locate the SD card slot on the internal dual SD module (IDSDM) card.
2. Press inward on the card to release it from the slot, and remove the card.
