About This Guide
This guide describes the installation of the 200 MHz/1 MB Processor Board
Accessory Kit in HP NetServer LXr Pro8 systems. The processor board includes
two 200 MHz/1 MB CPU chips, on which two heat pipes are mounted for
efficient cooling.
Use this guide to install up to three additional processor boards in a system that
already has one 200 MHz/1MB processor board installed.
In addition to the installation instructions, this guide contains regulatory
information.
Additional Information
For other information about your HP NetServer LXr Pro8, refer to the HP
NetServer LXr Pro8 User Guide.
Verify Contents
CAUTION Do not remove the processor board from its bag until you are
ready to install it. Make sure the bag remains sealed. The
CPU chips are sensitive to humidity, so desiccant has been
packed in the bag containing the processor board. When the
processor board has been installed and the HP NetServer is
running, the chips are no longer sensitive to humidity.
Unpack the shipping box and verify that you received the contents listed on the
next page for the 200 MHz/1 MB Processor Board Accessory Kit. If anything is
missing or damaged, or if the bag around the processor board is not sealed, call
your reseller.

Tools Required
• An antistatic service kit (3MTM 8501/8502/8503 or equivalent). This kit
includes a static-dissipating work surface, a chassis clip lead, and a wrist
strap.
• Number 2 Phillips head screwdriver.

2 Plan the Upgrade
Up to four processor boards, each with two 200 MHz/1 MB CPU chips, can be
installed in the HP NetServer LXr Pro8 system. All four processor board slots on
the system board must be filled, even when fewer than four processor boards
(eight CPUs) are installed. Each processor board slot must contain one of two
kinds of boards:
• Processor board. The processor board contains two 200 MHz/1MB CPU
chips with two heat pipes and two VRMs (voltage regulator modules).
or
• Terminator board. The terminator board uses the same board blank as
the processor board, but it does not contain the CPU chips, heat pipes, or
VRMs. Each terminator board contains just the components necessary to
terminate the bus.
During start up, the control panel of the HP NetServer LXr Pro8 displays how
many CPUs the system detects.
Determine Where to Place the Processor Board
The system comes standard with one processor board and three terminator
boards. Before you can add a processor board, you must remove a terminator
board.
The HP NetServer LXr Pro8 has two CPU buses: A and B. Bus A, containing
slots A1 and A2, is the primary bus. Bus B, containing slots B1 and B2, is the
secondary bus. Table 2-1 shows how processor boards can be added to the HP
NetServer LXr Pro8 to keep the two buses balanced.

3 Perform the Upgrade
The installation steps are as follows:
1. Power down the HP NetServer.
2. Slide out the satellite chassis.
3. Lift and remove the cover of the satellite chassis.
4. Remove the terminator board.
5. Install the processor board.
6. Slide the satellite chassis back into place.
CAUTION The processor board and CPU chips are sensitive to static
electricity, and can be easily damaged by improper handling.
Do the following when handling the accessory kit:
•Leave the processor board in the antistatic container until
you are ready to install it.
•Use an antistatic wrist strap and a grounding mat.
•Before you remove a processor board from the antistatic
container, touch a grounded, unpainted metal surface on
the HP NetServer to discharge static electricity.
Power Down the HP NetServer
1. Log off all users and shut down all networking software and applications.
2. Press the DC power switch on the HP NetServer's control panel as shown
in Figure 3-1.

NOTE After you unlock the power interlock switch, there is no power
present at any internal or externally accessible area of the
satellite chassis. However, five volts of power are present at
the power supply pins on the base chassis where the satellite
attaches. To remove all power, unplug the AC power cord.
Slide Out the Satellite Chassis
CAUTION Wear a wrist strap and use a static-dissipating work surface
connected to the chassis when handling components. Ensure
that the metal of the wrist strap contacts your skin.
1. Put on the antistatic wrist strap and place the antistatic mat on a firm
surface near the system. Connect the strap and mat to an unpainted metal
surface on the system chassis.
2. Look at any cables you might have connected to PCI cards. If there is not
enough slack in one or more cables to pull out the satellite chassis,
disconnect the cables as necessary.
3. Remove the retention bracket from the lower rear of the NetServer and set
it aside. See Figure 3-3.
CAUTION You will need to replace the retention bracket when
redocking the Satellite Chassis. The bracket ensures correct
mechanical connection.
