■Connections between enclosures
If enclosures are installed in multiple racks or are installed with space in the same rack, the QSFP cables
(0.75m) that are included with the ETERNUS DX Disk storage system may be too short for connections
between enclosures.
In this case, use the Extension cable between enclosures. The length of the Extension cable between
enclosures that is provided is 3m or 6m. Enclosures in different racks can be installed within this length.
