Ultrastar Data102 Installation Procedure - Western Digital Ultrastar Data102 Installation Manual

Installation Guide
Cable Management
There are two different options for cable management in Ultrastar Data102: CMA Standard and CMA
Lite. Each of these options has a different installation, configuration, and purpose. The standard CMA
configuration manages and protects the full cable load during normal operation of the Ultrastar Data102. If a
fully-configured Ultrastar Data102 is not necessary, CMA Lite provides a better management and protection
solution for a lighter cable load, with a more compact hardware footprint. Utilizing front spacer brackets
that shift the enclosure forward, and narrower basket clips for tighter cable management, CMA Lite allows
the enclosure to fit within shallower racks and/or those with front and rear doors. The following information
provides a list of the features of each cable management option:
CMA Standard:
• Enables use of all I/O connections
• Manages and protects full set of cables during installation, operation, and servicing
• Easy cable routing with the open-top cable baskets
• Toolless installation
CMA Lite:
• Smaller rack footprint for shallower racks and/or racks with doors
• Manages and protects a lighter cable load (with only one CMA arm) during installation, operation, and
servicing
• Easy cable routing with the open-top cable baskets
• Toolless installation
CMA and CMA Lite in the Installation Procedure
The installation procedure for the Ultrastar Data102 includes instructions for both CMA Standard and CMA
Lite. These instructions are labeled, in-line, to notify the user when a step or part of a step is used for one
option or the other. These options occur during the steps for rail installation, CMA installation, Cabling,
and securing the enclosure to the rack.
Attention: The CMA Lite replacement package includes a CMA arm and spacer brackets.
Replacing the CMA arm can be done with the enclosure in place in the rack. To replace the
spacer brackets, the enclosure must be removed from the rack.
