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.

Chapter 1 Introduction

Upgrading the Rack (LH 3r) Configuration

You can upgrade the LH 3r rack configuration without removing it from the rack, but you may find it easier to reinstall the CPU baseboard and install the chassis reinforcement bars when the LH 3r is removed from the rack and sitting on a workbench. When in the rack, the chassis reinforcement bars mount on the bottom of the LH 3r. If you do decide to remove it from the rack to perform the upgrade, refer to the documentation below.

CAUTION Do not pull the LH 3r forward in the rack without extending

the anti-tip foot. If the anti-tip foot is not extended, the rack assembly can tip over and injure you and damage the NetServer or rack.

For HP Racks

Refer to the HP NetServer LH 3/LH 3r User Guide. For cabling instructions, refer to the documentation that came with the rack, and to the Rack Cabling Reference

for the HP NetServer LH 4.

3 Installing LH 4 Components

WARNING Do not use memory or VRMs from the LH 3/LH 3r CPU

baseboard with the LH 4/LH 4r CPU baseboard. This may result in damage to components and put data integrity at risk.

Upgrading the HP NetServer LH 3/LH 3r to an HP NetServer LH 4/LH 4r requires several steps, but there are few differences between the two NetServers.

Remove any packing materials and position the following components where you can reach them from your work position.

CPU Baseboard Components

The LH 3/LH 3r has a CPU baseboard that accepts two Intel Pentium II™ Xeon processors, each with an associated Pentium II Voltage Regulator Module (VRM). The LH 4/LH 4r has a new CPU baseboard that accepts up to four Intel Pentium II Xeon processors and six new VRMs designed especially for the Intel Pentium II Xeon processors.

Processor and VRM Configurations

The HP NetServer’s CPU baseboard has four processor slots, labeled Processor 1 through Processor 4. It also has six voltage regulator module slots, labe led VRM 1/2, VRM 3/4, VRM 1, VRM 2, VRM 3, and VRM 4. VRM 1/2 and VRM 3/4 provide regulated power for the cache memory on the processors, and the other four VRMs supply power to the processors themselves. Figure 3-1 shows these slots on the CPU baseboard.

Add processors in ascending slot order. You must also add additional voltage regulator modules (VRMs) as you add processors, again in ascending slot order. There will always be VRMs in slots VRM 1/2 , VRM 3/4, VRM 1, and VRM 2, so a VRM is added to each corresponding slot as you install a new processor.

Refer to Table 3-1 to determine which VRMs must be installed for each processor.

10. Replace the boards in the memory cage. Lower the ejection levers to lock the board into place in the cage.

11. Close the cover of the memory cage.

Additional Processor, VRM, and Memory Configurations

The LH 4/LH 4r CPU baseboard is shipped with two processors, two terminators, and four VRMs. If you are installing additional processors at this time, refer to the processor upgrade kit documentation and install them, and install the new VRMs as well.

The LH 4/LH 4r CPU baseboard contains two 64 MB DIMM modules. If you are installing additional memory at this time, refer to the memory upgrade kit documentation and install it with the other DIMMs.

Installing the Chassis Reinforcement Bars

The chassis reinforcement bars are two metal bars that help hold the CPU baseboard in place in the LH 4/LH 4r chassis. Since the CPU baseboard fits into to small slots on the lower chassis reinforcement bar, you need to install these bars before installing the CPU baseboard.

Insert the chassis reinforcement bars next to the CPU baseboard, as shown in Figure 3-8. There are four Torx thumbscrews that secure the two bars to the chassis, and two Torx thumbscrews that connect the CPU baseboard to the top chassis reinforcement bar.

NOTE If you are installing the chassis reinforcement bars while the

LH 4r is in the rack, you must install them from underneath.

Figure 3-8. Installing the Chassis Reinforcement Bars

Chapter 3 Installing LH 4 Components

Installing the CPU Baseboard in the Chassis

The LH 4 CPU baseboard fits into the chassis snugly. Observe these pr ecautions:

• Check to make sure that you have removed the card guide and air baffle for

the LH 3 CPU baseboard. If it is still installed, it will prevent the LH 4 board from seating properly. See "Removing the CPU Baseboard Guide and Air Baffle" earlier in this manual, and refer to Figure 2-2.

• Check to see that the covers for the processor cage and memory cage are

screwed on, and that the VRMs are seated properly.

• The edge of the CPU baseboard that faces the rear of the LH 4 has a thin

metal liner that protects against radio frequency interference. This material may snag on the chassis edge and crumple. If you have problems seating the board, check to see if the metal liner is catching on the chassis.

1. Use two people to lift the CPU baseboard, one holding each end. One

person can do it, but it’s easier with a person on each end.

2. Raise the ejection levers into a vertical positio n, as shown in Figure 3-8.

Slide the CPU baseboard into place. In the LH 4 (pedestal) configuration, lower it from the top of the LH 4. In the LH 4r (rack) configuration, slide it in gently from the side.

CAUTION The side of the CPU baseboard facing the front of the LH 4

fits into the long black guide slot mounted to the chassis. The side of the CPU baseboard facing the rear of the LH 4 fits into two slots that frame the connectors on the rear edge of the CPU baseboard. Note the metal liner around the edge of the CPU baseboard and be careful not to snag it on the chassis. See Figure 3-9.

4. Attach the two Torx thumbscrews to secure the CPU baseboard to the chassis, as shown in Figure 3-9.

5. Insert the new technical reference card in the sleeve on the inside of the NetServer cover, then replace the covers on the NetServer.

Installing a Redundant Power Supply

The LH 3/LH 3r runs on two power supply modules, and can accept a third to assure power continuity if a single power supply fails. The LH 4/LH 4r needs three power supply modules and can accept a fourth to assure power continuity if a single power supply fails.

If your LH 3/LH 3r does not already have a second power supply cage and redundant power supply, install the Power Supply Upgrade Kit. If you require power supply redundancy, order a fourth power supply module. To install the power supply hardware, refer to the instructions supplied with the kits.

Installing a Redundant Fan

The Power Supply Upgrade Kit contains an extra fan to provide extra cooling and redundancy for power supply cooling. If you install the power supply upgrade, install the redundant fan according to the installation directions.

Installing the LH 4r in the Rack

If you removed the LH 3r to upgrade it, refer to the documentation listed below to install the LH 4r in the rack.

For HP Racks

Refer to the HP NetServer LH 3/LH 3r User Guide. For cabling instructions, refer to the documentation that came with the rack, and to the Rack Cabling Reference

for the HP NetServer LH 3.

For Non-HP (Compaq) Racks

Refer to the HP NetServer LH 3 Non-HP Rack Installation Guide. For cabling instructions, refer to the documentation that came with the rack, and to the Rack

Cabling Reference for the HP NetServer LH 3.

Chapter 3 Installing LH 4 Components

Finishing the Hardware Upgrade

As the last step in the LH 3/LH 3r to LH 4/LH 4r upgrade, attach the new nameplate to the top of the front surface of the front bezel, as follows:

1. Orient the nameplate so that it can be read correctly when attached.

2. Secure the nameplate to the front bezel, as follows:

◊ For the LH 4, pry off the LH 3 nameplate in the upper left corner, then

snap the LH 4 nameplate into place.

◊ For LH 4r with the HP rack front bezel, insert the tab at one end of the

nameplate into the slot in the bezel, bend the nameplate slightly, and simultaneously insert the snaps on the back of the nameplate and the tab at the other end of the nameplate.

◊ For the LH 4r with the Compaq rack front bezel, insert the snap at one

end of the nameplate, and then insert the other snaps successively.

3. Attach the label reading "intel inside pentium II xeon" to a convenient location near a corner of the front bezel.

Chapter 4 Updating Firmware

CAUTION This Embedded NetRAID update only updates the firmware

on the CPU baseboard. When you reboot the NOS after this update, you will get an error message caused by conflicts between the NetRAID information stored elsewhere in the system and the new information saved in the CPU baseboard firmware. Use the HP NetRAID Express Tools utility to reconfigure your system, based on the configuration deta ils you documented before starting the upgrade.

10. Enter the Setup utility by pressing F2 at the screen prompt. Run "Clear Config" to clear the SCSI Controller, Embedded RAID, and system configuration.

NOTE If you do not push F2 quickly enough, you may be immediately

routed to the HP NetRAID Express Tools utility to remedy the problem noted in the above CAUTION. Perform the Embedded RAID reconfiguration, then proceed to the Setup reconfiguration.

11. Reconfigure Embedded RAID and Setup according to the configuration you saved earlier. You should not need to reinitialize the hard disks.

12. Reboot the system and:

A. Reconfigure Integrated Remote Assistant B. Clear the System Event Log

Update the Operating System

NOTE If you are upgrading from a single-processor to multi-processor

machine, you may have to reinstall the operating system. Please consult with your operating system vendor.

WARNING Navigator will prompt the user, "Would you like to use HP’s

automated mode of NOS Installation?" The default is "Yes." If you choose "Yes," whatever was on the C: drive will be lost.
