Cable Routing Procedures for Dell PowerEdge R620 Systems
10
Section 3: Cabling a PowerEdge R620 system on sliding rails
without a CMA
NOTE:
The CMA for Dell PowerEdge R620 is optional. Without the CMA installed, the system must be
powered down and all cables disconnected before it can be extended out of the rack.
3.1.
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 outer CMA attachment bracket as described in the
Rack Installation
Instructions
. See Figure 9 for an example of data cables secured to the left outer CMA bracket and
power cables secured to the right outer CMA bracket (as viewed from the rear of the system).

3.2.
Removing the outer 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 from the sliding rails 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 that secure the brackets to the rails as shown in Figure 10. Use the hook-and-loop
straps supplied with the rail kit to secure the cables to the rack frame if desired.
