Additonal Processor Installation 3

Overview

This document provides important information for installing the second

processor in Dell PowerEdge R520 and PowerEdge R420 systems.

Before You Begin

To install a second processor in your system, you must ensure that you have:

• Replaced the dummy fan in the FAN 6 slot with a cooling fan.

For more information on replacing the fan, see "Removing a Cooling Fan"

and "Installing a Cooling Fan" in the relevant Owner’s Manual on

support.dell.com

• Upgraded the riser cards as indicated in the table below:

For more information on replacing the riser cards, see "Expansion Cards

and Expansion-Card Risers"

and

Technical Specifications

in the Owner’s

Manual at

support.dell.com

NOTE: When selecting or upgrading your system configuration, verify the system

power consumption with the Dell Energy Smart Solution Advisor at dell.com/ESSA

to ensure optimum power utilization.

Removing a Processor Blank

CAUTION: Many repairs may only be done by a certified service technician. You

should only perform troubleshooting and simple repairs as authorized in your

product documentation, or as directed by the online or telephone service and

support team. Damage due to servicing that is not authorized by Dell is not covered

by your warranty. Read and follow the safety instructions that came with the

product.

Before upgrading your system, download the latest system BIOS version

from

support.dell.com

and follow the instructions included in the

compressed download file to install the update on your system.

NOTE: You can update the system BIOS using the Dell Lifecycle Controller.

Turn off the system, including any attached peripherals, and disconnect

the system from the electrical outlet. When disconnected from AC power,

press and hold the power button for 10 seconds to fully drain the system of

stored power prior to removing the cover.

NOTE: It is recommended that you always use a static mat and static strap

while working on components in the interior of the system.

Open the system. See "Opening the System

in the Owner’s Manual.

Remove the cooling shroud. See "Removing the Cooling Shroud" in the

Owner’s Manual.

CAUTION: The processor blank is held in its socket under strong pressure.

Be aware that the release lever can spring up suddenly if not firmly grasped.

Position your thumb firmly over the processor-blank socket-release lever

and release the lever from the locked position by pushing down and out

from under the tab. Rotate the lever upward.

Rotate the processor shield upward and out of the way.

Lift the processor blank out of the socket and leave the release lever up so

that the socket is ready for the new processor. See Figure 1-1.

Installing the Second Processor

CAUTION: Only trained service technicians are authorized to remove the system

cover and access any of the components inside the system. Before you begin this

procedure, review the safety instructions that came with the system.

Ensure that you have followed the steps mentioned in "Before You Begin"

on page 3.

Unpack the new processor.

CAUTION: Positioning the processor incorrectly can permanently damage the

system board or the processor. Be careful not to bend the pins in the socket.

CAUTION: Do not use force to seat the processor. When the processor is

positioned correctly, it engages easily into the socket.

Align the notches in the processor with the socket keys on the ZIF socket

and set the processor lightly in the ZIF socket. See Figure 1-1.

Close the processor shield.

Using a clean lint-free cloth, remove the thermal grease from the heat sink.

CAUTION: Applying too much thermal grease can result in excess grease coming

in contact with and contaminating the processor socket.

Open the grease applicator included with your processor kit and apply all

of the thermal grease in the applicator to the center of the topside of the

new processor.

Place the heat sink on the processor.

Tighten the heat-sink retention sockets. See Figure 1-2.
