2 Installing Memory in the 4 GB
Memory Board
This chapter includes guidelines and instructions for:
•Powering down the NetServer
•Removing the existing 4 GB memory board for a memory upgrade
•Installing 128 MB SDRAM DIMMs in the specified DIMM slot
configuration on the 4 GB memory board
•Removing 128 MB SDRAM DIMMs and downsizing the memory
configuration
•Installing the 4 GB memory board
•Powering up the system
Installation Basics
The HP NetServer LXr Pro8 accepts up to two memory boards. Each board has
32 DIMM sockets and accepts only 128 MB SDRAM DIMMS, for a maximum
capacity of 4096 MB per board. The minimum memory configuration is one
memory board with two 128 MB SDRAM DIMMs.
Use only 100 MHz HP 128 MB SDRAM DIMMs listed on the Product Reference
Label, which is located on the top of the HP NetServer chassis.
CAUTION The information in this section is important background
information for the installation of 128 MB SDRAM DIMMs
in the 4 GB memory board. You should not begin the actual
installation process now. Refer to the Installation Procedure
section when you are ready to begin installation.
Please note the following installation guidelines before adding memory:
•The minimum memory configuration is one memory board with two 128
MB SDRAM DIMMs.

Chapter 2 Installing Memory in the 4 GB Memory Board

•The memory board DIMM slots are numbered from M0 to M31 as shown
in Figure 2-1.
•The recommended memory configurations and the slot numbers where
SDRAM DIMMs are installed are listed in Figure 2-2 and Figure 2-3.
Add SDRAM DIMMs only in these quantities and in the specified slot
numbers.
Figure 2-1 shows the DIMM slot numbers on the 4 GB Memory Board. Board
jumpers are preset to the memory board revision level.

Figure 2-2 shows memory configurations when one 4 GB Memory board is
installed. Figure 2-3 shows configurations when two 4 GB memory boards are
installed. The Figures show the recommended order in which DIMM slots are
filled as you add 128 MB SDRAM DIMMs to the 4 GB boards: An "X" indicates
that a SDRAM DIMM is installed in each of the slots shown:

Tools Required
To remove or install a memory board, first remove the satellite chassis lower fan
module and the rear access panel. These tools are required for removal and
installation of accessories:
• Number 1 Phillips head screwdriver
•An anti-static service kit (3M8501/8502/8503 or equivalent). This kit
includes a static-dissipating work surface, a chassis clip lead, and a wrist
strap.
Power-Down Procedure
Power to the satellite chassis must be turned off before removing or installing the
4 GB memory boards.
1. Save your existing system configuration.
2. Log off all users, shut down all networking software, applications, and the
operating system.
3. Press the DC power switch on the HP NetServer's control panel (Figure
2-4).

4. Unlock the power interlock switch at the back of the HP NetServer's rear
panel by turning it clockwise (Figure 2-5). The switch turns off DC power
to the HP NetServer, and also unlocks the satellite chassis. See the HP
NetServer LXr Pro8 User Guide for more details on opening and closing
the HP NetServer chassis.
NOTE After you unlock the power interlock switch, DC power is
turned off for all components within the satellite chassis
except for five volts at the system control board which is
located on the SCSI Extender Tray in the bottom of the lower
board cage area. If you undock the satellite chassis from the
base unit, there is no power present at any internal or
externally-accessible area of the satellite chassis. However,
five volts are still present at the power supply connector where
the satellite chassis attaches. To remove all power, unplug the
AC power cord.

Accessing the Lower Board Cage
The lower board cage holds the NetServer’s memory boards. To reach these
boards, you extend the satellite chassis and remove the lower fan module and rear
access panel.
NOTE If the server is mounted in a rack, cables most likely run from
the satellite chassis to other rack components. If these cables
prevent easy access to the satellite, or could stop the satellite
from sliding out completely, disconnect them.
To access the lower board cage:
1. Remove the retention bracket from the lower rear of the NetServer and set
it aside. See Figure 2-6.

Chapter 2 Installing Memory in the 4 GB Memory Board

CAUTION You will need to replace the retention bracket when
redocking the Satellite Chassis. The Bracket ensures correct
mechanical connection.
Figure 2-6. Location of the Retention Bracket
2. Stand behind the HP NetServer and grasp the two ejector handles on the
HP NetServer’s rear panel. Pull both handles down firmly, and then pull
the satellite toward you. Pull it out until its slides are fully extended. The
slides lock in the extended position, so that the satellite cannot move
while you service it (Figure 2-7).

2. Remove the lower fan module, as shown in Figure 2-8:
a. Grasp the handles on either end of the fan module and push them
toward each other.
b. While continuing to push on the handles, pull the fan module toward
you. The module slides backward off its mounting rails.

Removing the Existing 4 GB Memory Board
The HP NetServer has one 4 GB memory board installed. Follow these steps to
remove the existing memory board for a memory upgrade:
1. After removing the rear access panel, locate the existing 4 GB memory
board (Figure 2-10).
2. On the memory board, open the two retaining clips toward you.

3. Hold the memory board by the corners, and carefully pull the board from
its slot until the edge connectors are free of the system board connectors.
4. Place the memory board component-side up on a firm anti-static surface
for protection.

Installing 128 MB SDRAM DIMMs on the 4 GB
Memory Board
Follow these steps to install a 128 MB SDRAM DIMM in a slot on the 4 GB
memory board.
CAUTION Use only 128 SDRAM DIMMs acquired from HP. Contact
HP Customer Support for a list of qualified 128 MB SDRAM
DIMMs. HP will not support configurations that use non-HP
SDRAM DIMMs.
1. If you are installing a new memory board, remove the 4 GB memory
board from its anti-static container.
2. With the board resting flat, component-side up, on a firm anti-static
surface, orient it so that the edge connector faces you.
3. Remove an HP 128 MB SDRAM DIMM (Figure 2-11) from its container,
handling the module by its edges. Lay it on an anti-static surface.

NOTE Refer to "Installation Basics" for a refresher on installation
guidelines. Figure 2-1 to Figure 2-3 provide important visual
clues for simplifying SDRAM DIMM installation.
