5.5.1 Cabling for CMA Standard and CMA Lite
5.5.1.1 Before You Begin
The cable configurations detailed in this section are intended to provide the optimal setup for your
specific configuration. During the cabling of the CMA, the HD Mini-SAS and SFP+ cables should be
installed into the CMA first, followed by Ethernet cables, and finally the power cables on top.
How to Use the Service Loop Dimension Figure and Table
This section uses the concept of service loops to inform the user on how to prepare HD mini-SAS cables
for installation into either the CMA Standard or CMA Lite. The power and Ethernet cables do not need to
be added to the Service Loop bundle. This concept utilizes measurements that begin at the connector
end of the cable and along the cable itself. The Service Loop Dimensions figure and the Service Loop
Dimensions table are paired together to communicate the length in which connectors, velcro, and the
CMA cage must be set at to avoid binding or snagging.
Note: The measurement provided in this section are only suggested values based on
product testing. Your specific situation may vary. Adjust the measurement as necessary to
avoid cable binding or sagging below the rear of the enclosure.
1. Identify the configuration that is needed for the particular setup and locate the Service Loop
Dimension table related to that configuration.
2. Take the first measurement (letter A) and measure that length from the connector on the cable to the
edge of where the first verco strip will go. Apply the velco strip.
3. Repeat this action for the B and C values until the table has been completed.
