1 Introduction
This document describes how to mount an HP NetServer LH 3r into a Compaq®
model 4000- or 7000-series rack enclosure. Refer to the HP NetServer LH 3r
Road Map and the HP NetServer LH 3/3r User Guide that came with the
NetServer for instructions on adding accessories to and configuring the
NetServer.
The HP NetServer LH 3 (the pedestal version of this NetServer) cannot be
installed in a rack enclosure. If you want to convert an LH 3 to an LH 3r for
installation in a rack enclosure, contact your HP Reseller for information about
the available conversion kit (HP NetServer LH 3 Pedestal-to-Rack Conversion
Kit). The HP NetServer LH 3 and LH 3r are shown in Figure 1-1.

WARNING To prevent the rack from tipping over and causing equipment
damage or bodily injury, be sure that the stabilizing, anti-tip
feature is installed on this rack enclosure (see Figure 1-2).
WARNING To prevent the rack from tipping over and causing equipment
damage or bodily injury, do not extend more than one piece
of equipment at a time out of the front of the rack enclosure.
Be sure that the stabilizing, anti-tip feature is installed on the rack enclosure in
which you are installing the HP NetServer LH 3r. This option consists of two
"feet" at the front of the base of the enclosure and, if you are installing this
NetServer in a single rack enclosure, two "feet" each on the left and right sides of
the enclosure (see Figure 1-2).

HP NetServer LH 3r – Compaq Rack Precautions
CAUTION If this NetServer is not installed according to these
instructions, damage to the NetServer or accessories may
result. Damage due to improper installation is not covered by
the HP Warranty. Observe the precautions listed in this
section to maintain the NetServer’s reliability.
When the HP NetServer LH 3r is installed in a Compaq rack enclosure, certain
requirements must be addressed to assure that the needs of the NetServer are met.
This NetServer will meet the requirements designed for the NetServer if:
•The NetServer is installed in a Compaq model 4000- or 7000-series rack
enclosure. This NetServer is not supported in any other non-HP rack
enclosure.
•If you choose to use a door on this enclosure, only a Compaq model 4000-
or 7000-series door may be used. No other door may be used. The
enclosure may be used with the door open, closed, or removed.
•Mass storage devices listed in the Tested Products List (located on the
HP NetServer Navigator CD-ROM) are used exclusively in the NetServer.
•Use HP rack accessories. (Note that HP rack accessories are not optimized
for Compaq rack enclosures.)
Compaq rack accessories have not been tested with HP NetServer
products, but components such as monitors, keyboards, switchboxes, and
PDUs often work.
•Use APC®uninterruptible power supplies (UPS) with HP NetServers.
APC offers mounting kits for Compaq rack enclosures.
This NetServer is not supported in a rack enclosure under circumstances other
than those listed above.
See the "Warranty and Support" section of this document for additional support
considerations.

3 Installation
This section contains detailed instructions for installing an HP NetServer LH 3r
in certain models of Compaq rack enclosures.
Preparation
Before beginning the installation of the NetServer into the rack, you must prepare
the rack and the NetServer.
Determine the location at which the NetServer is to be installed in the rack
enclosure. Mark the bottom and top of this location on the rack columns. The HP
NetServer LH 3r measures 8 EIA units tall.
Marking the Installation Holes
You will mark two holes on each of the four columns to use for the bar nuts and
screws that hold the slide to the column.
When marking the holes, mark the outer surface of the column (see Figure 3-1);
on the front columns, this is the column surface facing forward; on the rear
columns, this is the surface facing rearward. Use tape or a marker pen to mark
the appropriate holes on each column.
To mark the slide mounting holes (refer to Figure 3-1):
1. Count up from the top of the unit below, marking the 20th and 22nd
holes.
2. Repeat for all four columns.
NOTE Do not place nuts or screws in the holes, only mark them.

Figure 3-1. Marking Holes for Installation
You will mark two holes on each of the front columns to use for the rack nuts where
the two recessed mounting brackets attach to the columns. When the installation is
complete, these brackets secure the NetServer in the rack enclosure.
To mark the bracket mounting holes (refer to Figure 3-1):
1. On the left front column, count up from the top of the unit below, marking
the 14th and 19th holes.
2. On the right front column, count up from the top of the unit below,
marking the 11th and 15th holes.

Installing the Bar Nuts, Screws, and Rack Nuts
Once you have marked the appropriate holes, install the bar nuts and screws on
the columns:
1. Position one bar nut behind holes 20 and 22 (previously marked).
2. Insert the two screws, with flat washers, through the two holes and start
them into the bar nut (see Figure 3-2). Do not tighten these screws, yet.
3. Repeat for all columns.

Figure 3-2. Installing Bar Nuts
Install two rack nuts in each of the two front columns:
1. Insert one rack nut in hole 14 and one in hole 19 (previously marked) in
the left front column only.
2. Insert one rack nut in hole 11 and one in hole 15 (previously marked) in
the right front column only.

Mounting the Slides
1. Orient each slide so that the front of the slide attaches to the front column
and the rear attaches to the rear column. This ensures that once installed,
the slides will extend correctly, toward the front of the rack (seeFigure3-3).
NOTE The slides do not come apart; they are one piece.

Extendible Members
Figure 3-3. Slide Components and Orientation
2. Place the mounting flange of the slide between the inside of the column
and the bar nut (see Figure 3-4). Do this at the front and rear of the slide.
3. Press the slide firmly against the columns, lift up against the screws, and
tighten all four screws.
NOTE It is very important to lift up on the slides prior to tightening
the screws. Tightening the screws without lifting up on the
slides will result in interference between the NetServer and
other equipment in the rack; you may not be able to slide the
NetServer into the rack enclosure after completing the
installation.
4. Repeat for the other slide.

Installing the NetServer
1. Extend the slides until you hear a click, indicating they are fully extended
in the locked-out position. Note that the slides do not come apart (see
Figure 3-3).
WARNING To prevent the rack from tipping over, be sure that the
stabilizing, anti-tip feature is installed on this rack enclosure
(see Figure 1-2).
2. Before you lift theNetServer, remove the power supply modules and the
hot-swap hard disk drives to reduce the weight.
WARNING This NetServer weighs up to 160 pounds (73 kg.) when fully
configured. Remove all power supply modules and hot-swap
hard disk drives before lifting the NetServer.
Use two people when moving theNetServer or lifting it into
the rack.

3. Using two people, lift the NetServer using the handles on each side. Move
the NetServer in between the extended slide members and position it so
that the handles are resting on the slide members (see Figure 3-5 and
Figure 3-6).
Figure 3-5. Lifting the Server Onto the Slide Members
4. Line up the mounting holes in the slide members with the holes in the
NetServer chassis, insert the three screws on each side, and tighten them
(see Figure 3-6).

5. Remove the two screws from each of the four handles and remove them
(see Figure 3-7). Keep these handles and screws for later use, in case you
need to remove the NetServer and ship it.
Figure 3-7. Remove Mounting Handles
6. Reinstall power supply modules and hard disk modules removed earlier.
Installing the Recessed Mounting Brackets
The NetServer is held in place (inside the rack enclosure) by two recessed
brackets. These are attached to the face of the NetServer chassis and the two front
rack columns.

To install these brackets:
1. On both slide members, simultaneously depress the lockout releases and
push the NetServer completely into the rack enclosure (see Figure 3-8).

Figure 3-9), and tighten.
5. Install two screws into the two holes in the right-hand recessed bracket
and into the two rack nuts (previously installed) on the right column (see
Figure 3-9), and tighten.
