2 Processor Upgrade Procedure—Increase L2

Cache Size

Introduction

This chapter provides procedures for upgrading HP 9000 rp3410 and HP 9000 rp3440 servers by replacing

dual processor modules. The change involves replacing existing processors with new processors that operate

at 800 MHz or 1 GHz and have increased L2 cache size. Included are instructions to protect your data, back

up the existing operating system (OS) software (in case of an error condition during the update), download

new firmware, and install new hardware. After performing these procedures, restart your server.

Required Tools

You need an ESD-safe workstation and special tools when replacing a dual processor module. You must use a

static-dissipating work surface and a wrist strap. The following tools are required:

• Electrically Conductive Field Service Kit (P/N 9300-1155)

• 1/4 inch flat blade screwdriver

• ACX-15 Torx® screwdriver

• Special processor tool kit, HP P/N 5069-5441

Back Up Your System

Before replacing a dual processor module, back up all data and your server OS. In the event of interruptions

(for example power failure or interference), it may be necessary to resume operation in the old configuration.

Back Up Your Data

Back up your data in accordance with local procedures.

Back Up the Operating System

Always keep a backup copy of the current operating system (OS) available for emergency use. The OS is

provided on the CD that shipped with your server. You can obtain a copy from your HP Information

Technology Resource Center (ITRC) or download the HP-UX

OS from http://www.software.hp.com.

Software/Firmware Requirements

Ensure the server meets the minimum software and firmware revisions listed below. Update as necessary.

• HP-UX 11i (December 2004 update)

• System Firmware 45.11 or greater

• Management Processor (MP) firmware E.03.15 or greater

Download Firmware and Shut Down the Server

To download firmware and shut down the server, proceed as follows:

Step 1. Make sure that all users are logged off and that the server is not in use.
