Drive Slot Numbering

You can install any suitable disk drive into any slot in the enclosure. The diagram

below shows how VessRAID’s drive slots are numbered. Whether you have the

original or plus carriers, the slots are numbered the same.

Slot numbering is reflected in the WebPAM PROe and CLU user interfaces. See

Figures 11, 12, and 13.
