WARNING 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 voltages.
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

1 Introduction
Verifying Contents
The contents of the shipping box include:
•One HP qualified DIMM.
•The HP NetServer LH 3/LH 3r DIMM Installation Guide.
CAUTION To avoid damaging the DIMM with electrostatic
discharge, handle the DIMMs in a static-free
environment only. Hold the module by its edges and
avoid touching its components. When you set down
a DIMM, always place it on its anti-static container.
Prepare for Installation
Gather the tools and the documentation you need to install the DIMMs
before removing them from their packaging.

2
Tools You Need
To install DIMMs, you need an anti-static service kit (3M
8501/8502/8503 or equivalent). This kit includes a static-dissipating

before adding memory:
•The minimum memory configuration for the
NetServer LH 3/LH 3r is one 128 MB DIMM.
•The system board DIMM sockets are numbered from 0 to 3, as
shown in Figure 3-1.
