About This Upgrade Accessory
This accessory kit is provided as an upgrade to both the HP NetServer LH 3 (the
floor-standing pedestal configuration) and LH 3r (the rack-optimized
configuration). This upgrade accessory may be used to replace an existing
processor module with a higher-speed processor, or to add a second processor
module to a single-processor system.
In a dual-processor configuration, both processors must be the same speed.
Installation Overview
This guide describes the tools required and the procedure for installing a
Pentium II™processor module into the HP NetServer. The installation procedure
includes instructions on how to:
•Remove the NetServer bezel and covers
•Remove the HP NetServer LH 3r system board
•Remove the existing processor module or terminator board (if necessary)
•Install a new processor module
•Install a new voltage regulator module (VRM)
•Install the system board
•Replace the covers
•Update the BIOS
NOTE All components of the upgrade kit must be installed in order
for the upgrade to function properly.

Accessory Kit Contents
This accessory kit contains the following items:
•Pentium II processor module
•Voltage regulator module (VRM)
•HP NetServer LH 3/LH 3r Navigator CD
•Processor cooling fan (provided with certain processor modules only)
Tools You Need
CAUTION Components of this accessory kit are sensitive to static
electricity and can be easily damaged by improper handling.
Read the following information carefully before you handle
the accessory components:
•Leave the components in the anti-static container until you
are ready to install them.
•Use an anti-static wrist strap and a grounding mat. Read
and follow the instructions included with the wrist strap
and mat.
•Before you remove the accessory from the box, touch a
grounded, unpainted metal surface on the system to
discharge static electricity.

Chapter 1Processor Module Installation
3
To install this accessory you need the following tools, plus the key for the front
lock,if the HP NetServer is locked:
•A portable field service grounding kit (3M part number 8505 or
equivalent) containing a wrist strap, anti-static mat, and cable. Use this kit
to prevent damage to the system from static electricity.
•A 1/4-inch flat-blade screwdriver.
Preparing for the Processor Upgrade
WARNING Before removing the cover, disconnect the power cord and
unplug telephone cables. Disconnect power cords to avoid
exposure to high energy levels that may cause burns when
parts are short-circuited by metal objects such as tools or
jewelry. Disconnecting the power cord also disables the
standby voltage; simply turning off the NetServer does not.
Disconnect telephone cables to avoid exposure to shock
hazard from telephone ringing voltages.
CAUTION Wear a wrist strap and use a static-dissipating work surface
connected to the chassis when handling components.
You must access the NetServer system board to install this accessory kit. Separate
procedures follow for removing the HP NetServer LH 3 bezel and covers and
removing the HP NetServer LH 3r system board.

Removing the HP NetServer LH 3 Covers
The bezel and cover 3 must be removed to access the system board.
Removing the Bezel
The bezel shown in Figure 1-1 is attached to the front of the NetServer chassis
with two snap-in connectors at the top front of the chassis and three tabs that fit
into three slots on the bottom front of the chassis.
1. Turn off the HP NetServer and disconnect the power cord and telephone
cord.
2. Unlock the bezel, using the supplied key, and remove it from the front of
the NetServer.
3. Pull the bezel forward until it unsnaps, then lift the bezel forward and
upward from the chassis face.

Removing the Cover Panels
The NetServer has three removable cover panels (see Figure 1-2):
•Cover 1 covers the side where the I/O board is located.
•Cover 2 covers the area above the processor.
•Cover 3 covers the side where the processor is located.
You will remove cover 3 to access the system board and upgrade the
NetServer processor module.
CAUTION The NetServer covers are heavy. Support them as you remove
them, and allow room to move them away from the NetServer
and for storage.
Figure 1-2. HP NetServer LH 3 Covers
1. Remove cover 3 by unscrewing the thumbscrew, pulling the cover forward
using the cover handle and then slightly sideways to disengage it.
2. Lift it up and away from the chassis.
Proceed to the section "Installing the Processor Modules" later in this chapter.

Removing the HP NetServer LH 3r System Board
The bezel and cover panels must be removed to access the system board.
Removing the Bezel
The bezel shown in Figure 1-3 has three clips that mount onto a hinge assembly,
which is secured to the NetServer chassis.
1. Turn off the HP NetServer and disconnect the power cord and telephone
cord.
2. To remove the bezel, pull it toward you until it comes free.

Extending the HP NetServer LH 3r from the Rack
Extend the NetServer chassis from the rack to access the cover panels and system
board.
WARNING Do not unscrew the NetServer until you have extended the
anti-tip foot from under the front of the rack. This anti-tip
device must be extended to prevent the rack and NetServer
from tipping over, which could damage the NetServer and
injure people.
1. Unscrew the NetServer chassis from the rack, as shown in Figure 1-4. Do
not unscrew the entire hinge or bracket from the chassis; remove only the
outer screws, so the hinge and the bracket remain attached to the
NetServer chassis (see Figure 1-5).
2. Pull the NetServer forward from the rack until the lockout device engages
with a click.

Removing Cover Panels
The NetServer has three removable cover panels (see Figure 1-6):
•Cover 1 covers the side where the I/O board is located.
•Cover 2 covers the area above the processor.
•Cover 3 covers the side where the processor is located.
You will remove cover 2 to access the system board and upgrade the
NetServer processors.
CAUTION The NetServer covers are heavy. Support them as you remove
them, and allow room to move them away from the NetServer
and for storage.

Removing the HP NetServer LH 3r System Board
Remove the system board from the NetServer chassis to upgrade the processor
modules. The system board is secured to the chassis by two retaining latches (see
Figure 1-7).

1. Lift the retaining latches to release the system board from its socket.
2. Lift the system board out of the NetServer, and place it component side up
on the anti-static mat. Lay the system board flat, with the metal crosspiece
on the top rear corner of the system board extending off the work surface
(see Figure 1-8).

Removing the Terminator Board
If your system has one processor, a terminator board is installed in the upper slot.
You must remove the terminator board before installing a processor module into
this slot. (See Figure 1-10).
1. Squeeze together the two retaining latches on the terminator board.
2. Pull the terminator board out of the socket.
Save the terminator board for future use.

Removing the Processor Module
If you are upgrading an existing processor module, you must first remove the
module from the slot.
To remove a processor module:
1. Press in on each processor module release latch until it remains in (see
Figure 1-11). If the latch does not stay in, you must hold it in while
removing the module.
2. Lift up on the processor ejector lever until the processor pops out of the
processor socket (see Figure 1-11).
CAUTION Do not move the processor ejector lever beyond its limit
(about 25-30 degree angle from horizontal). The ejector lever
may break if forced.
3. Remove the processor module from the mounting bracket assembly.

Installing a New Processor Module
To install a processor module:
1. Orient the new processor module as shown in Figure 1-12.
2. Slide the new processor module into the processor mounting bracket and
press it firmly into the socket. The processor module is seated when the
edge of the module is ¼-inch below the top of the processor mounting
bracket.
CAUTION If the NetServer has only one processor module, it must be
installed in the primary (lower) processor slot, and a
terminator board must be installed in the secondary (upper)
slot.
3. When the processor module is fully seated, check the two release latches
at the outer corners of the module. If the latches are not in the extended
position, pry out gently on the latch until it clicks into the extended
position.
CAUTION Do not use excessive force when prying out the processor
release latches. Use of excessive force will break the latch.
Latches broken due to use of excessive force are not covered
by any HP warranty.
