Internal dual SD module indicator codes 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. The IDSDM card offers the following features: • Dual card operation - maintains a mirrored configuration by using SD cards in both the slots and provides redundancy. NOTE: When the Redundancy option is set to Mirror Mode in the Integrated Devices screen of System Setup, the information is replicated from one SD card to another. • Single card operation - single card operation is supported, but without redundancy. The following table describes the IDSDM indicator codes: Table 12.
