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.
