9.1 Warnings and cautions

Warning: Failure to follow the guidelines in this section can cause serious issues
or additional system downtime.
Important: Western Digital Corporation recommends completing this procedure
under the guidance of Western Digital Corporation customer support.
When re-racking a system:
• Install and cable components one at a time. Use the cable labels to ensure that the cabling is correct.
Important: When cabling, system components are NOT interchangeable. For
example, do not cable the sixth Storage Node to the fourth Storage Enclosure
Basic.
• Install components in the order and location directed.
• Before powering the system back on, ensure that all components are:
– Cabled correctly
– Installed in the correct U-locations
After the installation is complete, it is the installer's responsibility to ensure that proper cooling is supplied
to the new rack. Use the
within recommended operating parameters.

9.2 Rack Requirements

Ensure that you new rack can meet the following requirements:
• System depth—Select a rack mounting solution that has a depth of 47.24 in (1200 mm).
• System height—Select a rack that can support 38U.
• System weight—Select a rack that can maintain a static load of 2000 lbs (907.18 kg)
• Rack rails—Select a rack with rails that are either:
– Set 798 mm from the front of the rack to the mounting surface.
– Back far enough to allow space for the molding of the power cords of the Storage Enclosure
Basics to go between or around the front vertical rails.
• Cabling and cable management—Select a cable management system that can route cables safely
through your system. Use the following guidelines:
– Cables are wired from the rear of the system. In the case of the storage enclosures, the cables
connect in the front of the rack and are run through cabling channels in the rail kit to the rear of
the rack.
– All cables provided are varying lengths based on the design of the whole system. The length of
each cable is based on the length needed to cleanly connect to the necessary component ports.
– There is a maximum supported length of seven meters for the DAC cables used in the ActiveScale
X100.
