Cable Routing Procedures for Dell™ PowerEdge™ R310 & R410 Systems

Introduction

This white paper covers recommended cable routing procedures for Dell™ PowerEdge™ R310 & R410
systems in the following racks:

• PowerEdge™ 4210/2410

• PowerEdge™ 4820/4220/2420

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™ R310 or R410 With a Cable Management Arm (CMA)

This section details how to cable a PowerEdge™ R310 or R410 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™ R410 system.

NOTE: PowerEdge™ R310 & R410 systems are not compatible with previous generation 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.
