Warnings
Observe the warnings below to prevent harm to you or the NetServer. Also
observe all cautions and warnings in this document and other documents to protect
people, the NetServer, components, and other equipment.
WARNING Before removing the cover, always disconnect the power
cord(s) and unplug telephone cables. Disconnect the power
cord(s) 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(s) to turn off standby
power. If the backlight on the LCD display is on, standby
power is still on.

Prepare for Installation
Gather the tools and the setup information you need before beginning the
conversion. Place the NetServer where there will be sufficient space to remove the
covers, power supply modules, and disk drives. If you plan to add accessory
boards or additional memory, reserve bench space at a comfortable level so you
can reach the interior of the NetServer easily.

2 Remove Bezel, Cover, and
Components
Overview of Removal of Front Bezel, Rack Rail
Cover, and Components
Before you convert the NetServer to the rack-optimized configuration, you will do
the following:
•Power down the NetServer and disconnect it.
•Remove the front bezel and rack rail cover.
•Lighten the NetServer by removing the hot-swap disk drives and the power
supply modules.
•Move the NetServer to a suitable work area.
•Remove the casters.
Disconnect the NetServer
Do the following to power down the NetServer and disconnect it:
1. Back up your system.
2. Bring down the network properly.
3. Turn off power to the HP NetServer.
4. Disconnect the AC power cord(s) and all external cables from the HP
NetServer.

Chapter 2 Remove Bezel, Cover, and Components

WARNING Before removing the cover, always disconnect the power
cord(s) and unplug telephone cables. Disconnect the power
cord(s) 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(s) to turn off standby
power. If the backlight on the LCD display is on, standby
power is still on.
CAUTION Never operate this HP NetServer without first installing the
covers and the front bezel. Operating the system without the
covers in place reduces critical cooling airflow over some
components, such as power supply modules, hard disk drives,
and processor modules. Operating the system without the
covers in place may result in failure of these components.
If you open the HP NetServer LH 3/3r or LH 4/4r while it is
operating, do not run it for more than 2 minutes. If you open
the HP NetServer LH 3000/3000r or LH 4000/4000r while it
is operating, do not run it for more than 60 minutes. Failure to
observe these precautions may result in thermal damage to the
NetServer.
CAUTION Wear a wrist strap and use a static-dissipating work surface
connected to the chassis when you remove or install
components.

Remove the Front Bezel and Rack Rail Cover
The rack rail cover is the only NetServer cover that must be removed during the
conversion of the NetServer from pedestal configuration to rack configuration.
First, unlock and remove the front bezel to gain access to the screw securing the
rack rail cover.
Remove the Front Bezel
The front bezel for the pedestal configuration connects to the front of the
NetServer chassis with snap-in connectors at the top front of the chassis and tabs
that fit into two slots on the bottom front of the chassis. To remove the bezel,
unlock the bezel lock with the key, and pull the bezel forward until it unsnaps.
Then lift the bezel forward and upward from the chassis face, as shown in
Figure 2-1.

Lighten the NetServer
Before you lift the NetServer, remove the hot-swap hard disk drives and power
supply modules. This will lighten the NetServer, so that fewer people will be
needed to lift it.
WARNING Do not attempt to lift the NetServer by yourself. Follow all
local regulations when moving the NetServer.
Failure to observe this warning could result in serious injury to
personnel or damage to the NetServer.
Take out power supplies and hot-swap hard disk drives before
lifting the NetServer.

when fully loaded. The HP NetServer LH 4r weighs up to
176 pounds (80 kg) when fully loaded.
The HP NetServer LH 3000r weighs up to 118 pounds (54 kg)
when fully loaded. The HP NetServer LH 6000r weighs up to
180 pounds (80 kg) when fully loaded.
Remove Hot-Swap Hard Disk Drives
CAUTION Wear a wrist strap and use a static-dissipating work surface
connected to the chassis when you remove or install hot-swap
disk drive modules.
1. Refer to Figure 2-3. To unlock the drive, push the locking latch in and then
pull the ejector handle toward you.
2. Gently pull the drive out about an inch to disengage the power connection.
3. Use your hand to support the bottom of the drive. Slowly pull the drive
straight out. Do not allow the drive to fall.
