Cable length verification
Before you install and connect the hardware, be sure to verify that you have the correct length of cables for your setup.
Each rack unit (RU) is 44.50 mm (1.752 inches) in height. The compute node is 2RU high.
The 5U84 Storage Shelves are 5RU high.
Four 1-meter (39.37 inches) SAS-3 cables ship with each compute node and connect to the Primary Storage Shelf.
Two SAS-3 cables ship with each Expansion Storage Shelf. Each SAS-3 cable is 1-meter (3.28 feet) long.
SAS-3 cables that are 2 meters (6.56 feet) long can be ordered separately. The 2-meter cable is long enough to connect the Primary Storage Shelf to the third Expansion Storage Shelf when you use the recommended configuration.
Note:
If you must have Expansion shelves in different racks be sure that the SAS-3 cables are long enough. Do not stretch the cables too tightly or try to use adapters or extensions.
