DELL R710 PowerEdge Server Instruction Manual

Introduction

This white paper describes recommended cable routing procedures, both with and without the optional Cable Management Arm (CMA) for the Dell™ PowerEdge™ R710 in the following racks:

PowerEdge 4210
PowerEdge 2410
PowerEdge 4220
PowerEdge 2420

If 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 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 White Paper “Best Practices Guide for Rack Enclosures.”

Cabling a PowerEdge R710 with CMA

This section details how to cable a PowerEdge R710 using a CMA. If you are cabling the system without the optional CMA, please refer to “Cabling a PowerEdge R710 Without a CMA” later in this white paper.

Follow the instructions contained in the Rack Installation Guide found in the rail kit to install the server into the rack and to install the cables. All illustrations in the following sections were created using a PowerEdge R710.

NOTE: The PowerEdge R710 is not compatible with previous‐generation rails and CMAs.

Installing 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. Plug in all applicable cables to the rear of the system. Verify that all connections are secure. See Figure 1.

Figure 1: System with Cables Installed

Route the Power Cables Through the Strain Reliefs

After the tray and cables are installed, route the power cables through the strain reliefs located on the power supply handles as shown in Figure 2.
Installation

Routing the Cables Through the CMA

NOTE: The CMA can be installed on either the right or left rear side of the rails. Mounting the CMA on the side opposite the power supplies (left side mount) is recommended; otherwise, the CMA must be disconnected in order to remove the outer power supply. Refer to “Replacing a Power Supply on a PowerEdge R710 with CMA” later in this white paper for details on power supply replacement.

NOTE: For guidelines on how to route cables within the rack, refer to the Dell White Paper “Best Practices Guide for Rack Enclosure”.

Left Side Mounting Instructions

Install the CMA on the left rear side of the rails by attaching both CMA housings to the attachment brackets on the rails. See Figure 3.
Route the cables through the CMA while keeping any twisting of the cables to a minimum. If the cable bundle includes a KVM dongle, place the dongle inside the CMA basket. Use the hook and loop straps on the CMA to secure the cables.
Figure 3: Routing the Cables Through the CMA
Once all the cables are routed through the CMA, dress the cables between the back of the system and the entrance of the CMA with the tie wraps provided in the CMA kit. The tie wraps are shown in yellow in all illustrations.
Clip off the excess length of material from the tie wraps and make sure that the tie wraps are positioned to avoid interference with adjacent systems.
Return the CMA to the closed (retracted) position.
Extend the system from the rack to verify there is sufficient slack in the cables at both the entrance and exit of the CMA.
See Figure 4 for an example of a completed left side mounted CMA installation.

Right Side Mounting Instructions

Install the CMA on the right rear side of the rails by attaching both CMA housings to the attachment brackets on the rails. Follow steps 2‐6 from the left side mounting instructions in the previous section. See Figure 5 for an example of a completed right side mounted CMA installation.

Cabling a PowerEdge R710 without a CMA **

**

NOTE: The CMA on the Dell PowerEdge R710 is optional. Without the CMA installed, the system must be powered down and all cables disconnected before it can be removed from the rack.

Routing the Cables

Plug in all applicable cables to the rear of the system, verifying that all connections are secure.
Using the hook and loop straps supplied with the rail kit, bundle the cables and secure them to either the left rail or right rail CMA attachment brackets as described in the Rack Installation Guide. See Figure 6 for an example of power cables secured to the right CMA bracket and data cables secured to the left CMA bracket.
It is recommended that the cables be secured to the outer brackets, but cables may be secured to the inner brackets if desired.

Installation

Replacing a Power Supply on a PowerEdge R710 with CMA

Remove the tray from under the CMA as described in the CMA Installation Instructions provided with the CMA kit.
Swing the CMA into the service position.
Disconnect the power cord from the power supply and disengage the strain relief.
Remove and replace the power supply
a. If the CMA is attached to the right side and the outer power supply needs to be replaced, the inner CMA attachment housing will need to be disconnected. While supporting the CMA with one hand, remove and replace the power supply with the other hand as shown in Figure 7.
b. If the CMA is attached to the right side and the inner power supply needs to be replaced, the CMA does not need to be disconnected.
c. If the CMA is attached to the left side, both power supplies can be removed without disconnecting the CMA.
Plug in the power cord.
Re‐engage the strain relief.
Replace the CMA support tray.
Return the CMA to the closed (retracted) position.

Cabling a PowerEdge R710 Installed in Static Rails

NOTE: The CMA is only compatible with sliding rails, and not with static rails.

Follow the instructions in the Rack Installation Guide included in the static rail kit to install the server into a 2‐ post or 4‐post rack.
Verify that the hook and loops straps provided with the static rail kit are installed to the rear of the rails.
Plug in all applicable cables to the rear of the system and verify that all connections are secure.
Using the hook and loop straps supplied with the rail kit, bundle the cables and secure them to either the left rail or right rail as described in the Rack Installation Guide. See Figure 8
