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.
