Cable Routing Procedures for the Dell PowerEdge R520 System
4
Introduction
This white paper covers recommended cable routing procedures for the Dell™ PowerEdge™ R520 system
in the following racks:
• PowerEdge 2410, 4210
• PowerEdge 2420, 4220, 4820 (including wide and deep versions)
• PowerEdge Energy Smart 4020S, 4620S
If you are using the optional cable management arm (CMA), following these procedures will allow you
to extend the system from the rack for service without powering down or disconnecting the cables. If
you are not using the CMA, following these procedures will ensure secure attachment and strain relief
of the cables behind the system.
For guidelines on how to route cables within the rack, refer to the Dell Best Practices Guide for Rack
Enclosure white paper. For additional details regarding potential interferences between the CMA and
rear-mount power distribution units (PDUs) in Dell racks as well as general information about third
party rack compatibility, refer to the Dell Enterprise Systems Rail Sizing and Rack Compatibility Matrix
located at
Section 1: Cabling a PowerEdge R520 system with a CMA
This section details how to cable the PowerEdge R520 system on sliding rails using a CMA. If you are
cabling the system without the optional CMA, refer to Section 3.
Follow the instructions contained in the Rack Installation Instructions in the sliding rail kit to install the
server into the rack. Once installed, use these instructions to install the cables. All illustrations in the
following sections were created using a PowerEdge R520 system.
NOTE: The PowerEdge R520 system is backward compatible with the PowerEdge R510 rails and CMA.
1.1. Connecting the cables to the system
Attach the CMA tray to the back of the rails as described in the CMA Installation Instructions provided
in the CMA kit. Connect all applicable cables to the rear of the system and verify that all connections
are secure. See Figure 1.
