Preface

Tools You Need

To install this accessory kit, you need the following tools:

• An anti-static service kit (3M

includes a static-dissipating work surface, a chassis clip lead, and a wrist strap.



8501/8502/8503 or equivalent). This kit

Power Supplies Needed

NOTE You will need to install an HP NetServer LH 3/LH 3r

Redundancy Kit as part of the LH 3 to LH 4 conversion, unless the LH 3/LH 3r already contains a second power supply cage and a third power supply. If you want to preserve redundancy, you should also install a fourth power supply. In this case, refer to the HP NetServer Power Supply Upgrade Kit Guide.

This table shows the power supply configurations for the LH 3 and LH 4 standard and redundant co nfigurations:

Standard Configuration Redundant Configuration

LH 3/LH 3r

LH 4/LH 4r

1 cage, 2 bricks 2 cages, 3 bricks: 2 in first cage, and 1

in second

2 cages, 3 bricks: 2 in first cage, and 1 in second

2 cages, 4 bricks: 2 in each cage

Precautions

Follow the procedures listed below to ensure safe handling of components and to prevent harm to yourself and the NetServer.

WARNING The HP NetServer LH 3r weighs up to 160 pounds (73 kg.)

when fully loaded. If you are removing the LH 3r from the rack, remove the power supplies and hard disk drives before doing so. Follow all local regulations when lifting the NetServer.

To prevent the rack enclosure from tipping over,

•

Extend the anti-tip foot on the rack

•

Verify that the leveling feet on the rack are lowered

•

Do not extend more than one piece of equipment at once

Before removing the cover, always disconnect the power cord and unplug telephone cables. Disconnect the power cord to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects, such as tools or jewelry. Disconnect telephone cables to avoid exposure to shock hazard from telephone ringing devices. Note that the power switch does not turn off the standby power. Disconnect the power cord to turn off standby power. If the backlight on the LCD display is on, standby power is still on.

Preface

CAUTION Never operate this NetServer without first installing all covers

and the front bezel. Operating the system without all covers in place reduces critical cooling airflow over some components, such as hard disk drives and processor modules. Operating the system without all covers in place may result in failure of these components.

Wear a wrist strap and use a static-dissipating work surface connected to the chassis at all times to prevent possible static electricity damage to the NetServer components.

1 Introduction

Installation Overv iew

This guide descri bes the procedures for installing new hardware and so ftware in your LH 4/LH 4r NetServer. The hardware update takes 10 or 15 minutes. The firmware update can take up to an hour, not including time taken by ba cking up and restoring your hard disk drives, or by reinstalling the NOS or applications. During the update procedure, you will see progress screens that indicate the action underway.

During the software upgrade, you will:

• update system information

• reconfigure options like interrupt management and NetRAID details

• reinstall the NOS if necessary

NOTE Before attempting the upgrade procedure, you should be

familiar with the current and default NetRAID configurations and with the BIOS options specified in the Setup utility. For further information, refer to these topics on the HP NetServer

Online Documentation CD-ROM:

HP NetRAID Installation and Configuration Guide HP NetRAID User Guide Setup Utility (in LH 4/LH 4r Configuration section)

CAUTION The software update eliminates user-definable BIOS options

and the NetRAID configuration details. You must save these details before you perform the software upgrade if you want to restore these settings afterward.

Chapter 1 Introduction

CAUTION After the system information update, your NetServer will

revert to the default NetRAID settings. You must restore your NetRAID configuration from your worksheets or from notes

before you can access the NetRAID arrays. If you do not save the NetRAID configuration details before performing the system information update, your data may be unrecoverable.

Briefly, the conversion takes several steps:

1. Back up the contents of your hard disks - both the system disk(s) and any RAID arrays.

2. Save the current system software configuration with the LH 3/LH 3r HP NetServer Navigator CD-ROM.

3. Gather the documentation, tools, hardware, and software needed to perform the conversion.

4. Perform the first part of the software upgrade, backing up data.

5. If you are upgrading an LH 3r, extend it from the rack. Be sure to extend the anti-tip foot, or use the anti-tip feature, before you extend the NetServer from the rack.

6. Remove cover 2, the cover protecting the top of the CPU baseboard, and cover 3, the cover shielding the components on the CPU baseboard side of the LH 3.

7. Remove the LH 3 CPU baseboard.

8. Install the power supply upgrade kit, or additional power supplies, if necessary.

9. Remove the CPU card guide and air baffle used with the old CPU baseboard.

10. Install memory and processors in the LH 4 CPU baseboard.

11. Install the chassis reinforcement bars.

12. Install the LH 4 CPU baseboard in the chassis.

13. Replace the covers.

14. Perform the second part of the software update from the HP NetServer Navigator CD-ROM and LH4UPD diskette.

Chapter 1 Introduction

15. Reconfigure the system with the Setup and NetRAID utilities, using the

configuration details you saved in step 2.

16. Verify that the system is restored to its operating configuration.

NOTE This procedure assumes that you are not performing other

procedures, such as installing new PCI cards, tape drives, or other hardware, or performing operating system upgrades, at this time. You can do these operations while performing the LH 3 to LH 4 upgrade, but minimizing changes makes troubleshooting much easier if problems or incompatibilities arise during the upgrade process.

Chapter 1 Introduction

Saving the Current Operating Environment

Before you start the upgrade, follow these instructions to preserve the current operating environment.

CAUTION You must back up all disks on your system - the disk

containing the NOS and any RAID arrays. Failure to perform

this step leaves you vulnerable to potential loss of data.

1. Back up all hard disks - both the hard disk containing the NOS, and any RAID arrays, using the backup utilities on your NOS. You will perform a restore later to replace this data.

2. You must write down all system configuration details from the Setup, Remote Management, and NetRAID utilities, as you will have to reconfigure them after the system software update. For a discussion of NetRAID implementation and usage details, refer to the HP NetRAID Installation and Configuration Guide and HP NetRAID User Guide manuals on the HP NetServer Online Documentation CD-ROM.

For example, note the following information:

A. Adapter:

∗ PowerFail Safeguard (Default is Enabled) ∗ Disk Spin Up Timings (Default is Automatic Spinup) ∗ Cache Flush Timings (Default: every 4 seconds) ∗ Rebuild Rate (Default: 50%) ∗ Auto Rebuild (Default: Enabled)

B. Logical Drive:

∗ RAID level ∗ Size ∗ Stripe Size (Default: 64 KB) ∗ Write Policy (Default: Write Through) ∗ Read Policy (Default: Adaptive)

Chapter 1 Introduction

∗ Cache Policy (Default: Cached I/O) ∗ Virtual Sizing (Default: Disabled)

C. SCSI Channel:

∗ Transfer Rate (Default: Ultra-2)

3. If you are using the Integrated Remote Assistant features, run the Integrated Remote Assistant. Record all configuration settings.

4. Ensure that the following features in the Integrated Remote Management utility are not enabled:

◊ Power off on critical temp ◊ Power off on critical voltage

5. From the "More NetServer Utilities" option in the Main Menu, view the Event Log Report Utility. If there are problems with the system, troubleshoot these before continuing with the upgrade. Refer to the HP

NetServer LH 3/LH 3r User Guide and the HP NetServer Online Documentation CD-ROM.

Preparing for Hardware Upgrade

Gather the tools and the setup information you need before beginning the conversion. Locate the HP NetServer where there will be sufficient space to remove the covers. Reserve bench space at a comforTable level so you can add processors, VRMs, and memory easily.

Follow these steps:

1. Shut down the network opera ting system.

2. Turn off the NetServer and display.

3. Disconnect all telephone cables and power cords.

4. Disconnect all cables attached to the system board connectors at the rear of the chassis.
