Preface
Purpose of this Guide
This guide describes the steps you need to perform to install the HP NetServer
LH 3/LH 3r Power Supply Upgrade Kit, HP Product Numbers D6093A and
D6095A, into an HP NetServer LH 3/LH 3r. The kit adds a third power supply
module (PSM) to the two PSMs that come standard with the server. The third
PSM allows the server to keep operating should one of the original PSMs fail.
This accessory kit contains a PSM, a power supply fan module, a filler panel, and
a power supply cage for the HP NetServer LH 3 or LH 3r.

NOTE All components of the accessory kit must be installed in order
for the power supply module to function properly.
Removing the Covers
CAUTION Never operate this NetServer without first installing all
covers. Operating the system without all covers in place
reduces critical cooling airflow over some components, such
as hard disk drives and processor modules. Operating the
system without all covers in place may result in failure of
these components.
WARNING Before removing the covers, 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 devices.
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 is on, standby power
is on.
CAUTION Wear a wrist strap and use a static-dissipating work surface
connected to the chassis at all times.

To remove the covers:
WARNING Turn off the HP NetServer and disconnect the power cord and
telephone cord.
1. Unlock the bezel lock with the key from the key bag located on the rear of
the HP NetServer (see Figure 1-1).
2. To remove the front bezel, pull the top of the bezel away from the chassis,
and then lift the bezel up and off of the chassis.

CAUTION Do not unscrew the LH 3r 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 LH 3r from tipping
over, which could damage the LH 3r and injure people.
To remove the covers:
1. Turn off the HP NetServer and disconnect all power and telephone cords.
2. Remove the screws securing the latch plate and the bezel hinge to the
rack. 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
LH 3r chassis. Pull the LH 3r forward from the rack until the lockout
device engages with a click (see Figures 1-2 and 1-3).

2 Cage and Power Supply Installation
Introduction
This chapter shows how to mount an additional power supply cage in an HP
NetServer LH 3 or LH 3r. It then describes how to install the power supply
module (PSM) in the empty cage.
NOTE Before beginning this procedure:
•Shut down the HP NetServer operating system.
•Turn off the power switch on the front panel.
CAUTION Unplug the power cord from the power supply units.

Power Supply Cage Installation
Before installing the power supply cage, remove covers 1 and 3 as described in
Chapter 1.
To install the cage, follow these steps:
1. Loosen the two Torx screws on the front panel to be removed cabinet
(see Figure 2-1).
2. Remove the fan module behind the power supplies. To remove the fan
module, loosen the thumbscrew, then pull the fan assembly out of the
cabinet using the handle. See Figure 2-1.

4. Remove the power supply module from the cage, then set the new cage
in the open bay.
5. Push in the cage most of the way. Align and guide the cage into the
chassis slowly.
6. There are three connectors to attach to install the power supply cage:
two large, white connectors that snap in place on the underside of the
circuit board, and one small, black connector that routes through the
rectangular slot in the circuit board and plugs into its top side.
First, attach the two large, white connectors. Attach the inner white
connector (farthest from you) first, then attach the outer white
connector. Make sure both connectors "click" into place and that the
plastic locks are secure.

Chapter 2 Cage and Power Supply Installation

Push the cage in all the way. Bring the small, black middle connector
up through the slot in the board above the power supply cage until the
connector "clicks" and the plastic lock is in place. Check to make sure
that the connector is secure. See Figure 2-3.
First, attach the two large, white
connectors.
Then, attach the small, black
connector.
Figure 2-3. Attaching the Power Supply Connectors
7. Fasten the cage in place with one screw on the side, lower rear. Fasten
the two screws into the rear chassis.
8. Reinstall the fan module.
Power Supply Installation
To install a power supply module (PSM) in the empty power supply cage, follow
these steps:
CAUTION When lifting a PSM, be prepared to support its weight. Hold
the PSM with two hands.

Chapter 2 Cage and Power Supply Installation

1. Set the new PSM in the open bay (see Figure 2-4). The power supply
can go into either side of the cage.
Set the new power supply
module in either side of the
open bay.
Figure 2-4. Setting the New Power Supply in the Open Bay
2. Push in the PSM, seat it firmly, and tighten the thumbscrews.
3. The new PSM fills only half the cage. Cover the other half with the
filler panel from the Upgrade Kit. Fasten the panel in place with its
thumbscrews.
The PSM is now installed. However, do not turn on the server until you install
the fan module from the Upgrade Kit. See Chapter 3.

3 Installing the Fan Module
Installing Fan Module
Once the power supply cage and module are installed in the server, install the fan
module from the Power Supply Upgrade Kit. Server power should still be off, and
the covers 1 and 3 should be off the NetServer. The module includes two fans. It
mounts directly in front of the existing power supply fan module.
1. Slide the fan module that you removed back into place.
2. Slide the new fan module into place in front of the existing power supply
fan module.
3. Fasten the fan module in place and secure it with its thumbscrew. See
Figure 3-1.
Slide the new
fan module into
place.

4. Replace covers 1 and 3. See "Replacing the Covers," in this section, for
details.
5. Remove the yellow tamper evident plug (not pictured) from the power
supply. Then plug in the power supply cord. The power cord retainer
holds the plug in place. To attach the power cord retainer, push up on the
metal piece underneath and secure it with the locking mechanism. See
Figure 3-2.

6. Check that the green LED at the front of each power supply is on. The
LED confirms that the power supply is functioning.
