Cable Routing Procedures for Dell™ PowerEdge™ R515 Systems

Introduction

This white paper covers recommended cable routing procedures for the Dell™ PowerEdge™ R515
system in the following racks:

 PowerEdge™ 2410
 PowerEdge™ 4210
 PowerEdge™ 2420
 PowerEdge™ 4220 (including wide and deep versions)
 PowerEdge™ 4820 (including wide and deep versions)

If you are using the optional 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

Guide for Rack Enclosure

white paper.

Best Practices

Section 1: Cabling a Dell™ PowerEdge™ R515 With a Cable Management
Arm (CMA)

This section details how to cable a PowerEdge™ R515 system using a CMA. If you are cabling the
system without the optional CMA, refer to Section 2.

Follow the instructions contained in the
the rack. Once installed, use these instructions to install the cables. All illustrations in the following
sections were created using a PowerEdge™ R515 system.

NOTE: PowerEdge™ R515 systems are compatible with the PowerEdge™ R510 rails and CMAs.

1.1 Connecting the CMA Cables to the System

Attach the CMA tray to the back of the rails as described in the
in the CMA kit. Connect all applicable cables to the rear of the system and verify that all connections
are secure. See Figure 1.
