4.Press the upper or lower switch button to change the ID number so that each connected RAID array and expansion unit uses a different loop ID.

Caution – The loop ID should only be changed while the expansion unit is powered off or not in use. After changing the loop ID, a power cycle is required to make the ID switch change take effect. Failure to cycle the power following a loop ID change can lead to unexpected results.

The default ID switch setting for RAID arrays is 0. The default range of available drive IDs for RAID arrays is 0 to 11 for 12 drives (the IDs 12–15 are ignored). The default ID switch setting for expansion units and JBODs is 1.
