Section 2: Cabling a Dell™ PowerEdge™ R810 System Without a CMA

NOTE: The CMA on Dell™ PowerEdge™ R810 systems is optional. Without the CMA installed, the
system must be powered down and all cables disconnected before it can be removed from the rack.


Routing the Cables

1. Connect all applicable cables to the rear of the system and verify that all connections are secure.
2. Using the hook and loop straps supplied with the rail kit, bundle the cables and secure them to

either the left or right CMA attachment brackets as described in the

Rack Installation Instructions


See Figure 6 for an example of data cables secured to the left CMA bracket and power cables
secured to the right CMA bracket.


It is recommended that the cables be secured to the outer brackets, but cables may be secured to
the inner brackets as well if desired.

Removing the CMA Brackets for Shallow Racks

If you are installing the system into a shallow rack (less than 1 meter deep) and you will not be
installing a CMA, the outer CMA brackets may be removed if necessary in order to allow the rails to fit
properly into the rack. Remove the brackets by using a #2 Phillips screwdriver to remove the screws
used to attach them to the rails as shown in Figure 7.
