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.
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 Overview
This guide describes the procedures for installing new hardware and software 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 backing 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.

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:

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 operating 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.

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.
For Non-HP (Compaq) Racks
Refer to the HP NetServer LH 3r Installation Guide for Compaq®4000/7000
Racks. 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.

Figure 3-2. CPU Baseboard Layout
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, labeled 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.
