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 $ ^{TM} $ 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 Best Practices Guide for Rack Enclosure white paper.

Section 1: Cabling a Dell $ ^{TM} $ PowerEdge $ ^{TM} $ 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 Rack Installation Guide in the 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™ 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 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.

1.2 Installing the Inner CMA Attachment Bracket

As described in the Rack Installation Instructions, locate and attach the appropriate inner CMA attachment bracket based on which side you wish to mount the CMA. Use the bracket marked "A" for mounting the CMA on the left side, and the bracket marked "B" for mounting on the right side. See Figure 2.

1.3 Routing the Power Cables Through the Strain Reliefs

After you have installed the tray and cables, route the power cables through the strain reliefs
