Connecting ES40 shelves
The cabling diagrams in this section show maximum configurations. Not all systems will have all the disk shelves shown in the
diagrams.
When connecting ES40 shelves, all the cables have HD-mini-SAS connectors at both ends.
Add shelf-to-shelf cables between shelves in a loop and to the controller as shown in the diagrams.
CAUTION:
When connecting SAS cables to the SAS cards, ensure there is sufficient slack in the cable to avoid
unnecessary strain on the cable connector and the SAS card when the controller is fully extended from the rack.
DD6400 with ES40 cabling
The DD6400 system supports a maximum of two ES40 shelves. The diagrams show a single shelf, and two shelves cabled in a
single loop.
