Installing The Network Daughter Card/LOM Riser 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

1. Remove the blade from the enclosure.
2. Open the blade.
3. Install the Network Daughter Card/LOM riser card:
a) Align the slots on the card edge with the projection tabs on the plastic bracket covering the mezzanine card
slots.
b) Lower the card into place until the card connector fits into the corresponding connector on the system board.
c) Secure the card with the two screws.
4. Close the blade.
5. Install the blade in the enclosure.

Management Riser Card

The management riser card provides two SD card slots and a USB interface dedicated for the embedded hypervisor.
This card offers the following features:
• Internal Dual SD interface — maintains a mirrored configuration using SD cards in both slots and provides
redundancy.
• Single card operation — single card operation is supported, but without redundancy.

Replacing The SD Card

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).
1. Enter the System Setup and ensure that the Internal SD Card Port is enabled.
CAUTION: If the Internal SD Card Redundancy option is set to Mirror Mode in the Integrated Devices screen
of the system setup, you must follow the instructions in step 4 through step 6 to avoid loss of data.
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.
2. Remove the blade from the enclosure.
3. If the Internal SD Card Redundancy option is set to Disabled, replace the failed SD card with a new SD card.
4. Install the blade in the enclosure.
5. Enter the System Setup and ensure that the Internal SD Card Port and Internal SD Card Redundancy mode is
enabled.
6. Check if the new SD card is functioning properly.
