1 Introduction
This document describes how to mount an HP NetServer LC 2000 into a
Compaq®model 4000- or 7000-series rack. Refer to the HP NetServer LC 2000
Installation Guide that came with the NetServer for instructions on adding
accessories to, and configuring the NetServer.
HP NetServer – 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 installing this HP NetServer 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 then 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.

Chapter 1 Introduction
2
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.
Safety Precautions
Always keep the following safety and environmental issues in mind, especially if
you install the HP NetServer in a Compaq rack:
l Optimum Operating Environment – The optimum operating conditions
for the HP NetServer is in an environmental controlled computer room
with a temperature range of 20 to 22°C (68 to 72°F) at 40 to 60% relative
humidity.
•Maximum Ambient Temperature - Ensure the maximum ambient
temperature does not exceed 35°C (95°F).
•Elevated Operating Ambient Temperature - The ambient operating
temperature within a closed or multi-unit rack assembly is likely to exceed
the room's ambient temperature. Ensure the temperature within the rack
itself does not exceed 35°C (95°F).
•Reduced Air Flow - As you mount equipment in the rack, ensure you
allow enough air flow for safe operation of the equipment. The
NetServer's fans will only operate correctly if both front and rear doors of
the rack allow free air flow (perforated openings), or are removed.
•Mechanical Loading - Uneven mechanical loading within the rack can
cause hazardous conditions. To prevent this in your installation plans,
place the heaviest components in the bottom of the rack, mounting all
components as low in the rack as is practical.
•Circuit Overloading - Ensure the total configuration of equipment in the
rack does not overload the supply circuit. To this end, check the
nameplate ratings on all equipment. Consider the effect of circuit
overloading on overcurrent protection and supply wiring.
•Reliable Earth Grounding - Maintain reliable earth grounding of
rack-mounted equipment. Give particular attention to supply connections
that are not direct connections to the branch circuit: for example, using
non-HP power strips.

2 Preparing the HP NetServer for
Rack-Mounting
Introduction
This chapter describes how to remove the top cover and the pedestal from the
HP NetServer LC.
WARNING Before removing the top cover, shut down the operating
system and disconnect the power cords and unplug telephone
cables. Disconnect the power cords 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 a shock
hazard from telephone ringing voltages.
Tools Required
l An anti-static service kit (3M 8501/8502/8503 or equivalent). This kit
includes a static-dissipating work surface, a chassis clip lead, and a wrist
strap.

Chapter 2 Prepare the HP NetServer for Rack-Mounting

Removing the HP NetServer’s Top Cover and
Pedestal
Use this procedure to remove the bezel, top cover, and pedestal from the pedestal
version of the HP NetServer LC 2000.
WARNING Do not operate the HP NetServer with its covers removed.
Always disconnect the power cord before removing any
covers, 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 any telephone cables to avoid
exposure to shock hazard from telephone ringing voltages.
CAUTION To prevent overheating, never operate the NetServer with its
cover removed. This includes the power supplies and Hot
Swap hard disks, which must be replaced or the opening
covered immediately (within 2 minutes).
1. If the HP NetServer is operating, log off all users and if necessary back-up
files.
2. Follow instructions in your network operating system (NOS)
documentation to gracefully shut down all networking software and
applications.
3. Press the power switch on the HP NetServer’s control panel when
prompted by the operating system.
Normally, this completes the power down procedure.
4. Disconnect the power cord from its power source.

Removing the Bezel
1. Pull the top of the bezel forward until it unsnaps.
2. Lift the entire bezel upward and away from the chassis. See Figure 2-1.
The bezel connects to the front of the HP NetServer chassis with two snap-in
connectors at the top front of the chassis and two metal tabs, which fit into
two slots on the bottom front of the chassis.
Figure 2-1. Removing the HP NetServer LC 2000 Bezel
CAUTION To prevent damage to the covers, support the cover as you
remove it from the HP NetServer. The NetServer’s covers can
be easily damaged.

pedestal, which must be removed to mount the server in a rack.
NOTE The front bezel is shown removed, but the bezel may remain
on the chassis while removing the pedestal.
1. Disconnect all cables connected to the rear of the NetServer that would
limit its rotation before continuing.
2. Turn the NetServer over onto its top and pull up on the two tabs as shown
in Figure 2-3.

Chapter 3 Rack-Mounting the HP NetServer
12
The HP NetServer rack mount kit requires five EIA units of space in the rack.
Before mounting the NetServer, plan the NetServer’s location in the rack relative
to other rack components. Proper placement is vital both for safetyand operating
efficiency. For more details, see the HP Rack Installation Road Map and the
HP NetServer LC 2000r Rack Cabling Reference Guide.
NOTE If the HP NetServer is completely configured by the vendor
before delivery to the customer, then mounting the HP
NetServer in the rack may be the final step in the installation
procedure. If the vendor configures the HP NetServer at the
customer’s site, installation of the network operating system
and other software may occur after the HP NetServer is
mounted in the rack.
WARNING The HP NetServer weighs 80 lbs. (36 kg) fully loaded. To
prevent an accident, use two people when placing the
NetServer into the rack.
CAUTION If other rack components are to be mounted in the rack below
the HP NetServer, install those components before starting to
mount the NetServer.
Tools Required
To assemble the rack mount kit and install the HP NetServer on it, you need
these tools.
•T-15 and T-25 Torx Drivers
•Number 2 Phillips screwdriver
l Marking pen

Chapter 3 Rack-Mounting the HP NetServer

Preparing the Rack
The column adapters and cage nuts must be connected to the rack before
mounting the slide mechanism. Once the slides are correctly mounted, then the
HP NetServer LC 2000r can be installing into the rack.
HP NetServer Rack Mount Parts List
Ensure the rack-mounting kit provided with the HP NetServer and the non-HP
rack mount kit contain the following parts.
Table 2-1. Parts for Rack Mount Kit
Quantity Description
2 Slides
4 Washers
6 M6x16 Cage Nuts
8 Cage Nut Screws (M5 x 16mm)
6Screws for Slides (8-32 x ¼ inch, 4 panhead and 2
flathead)
2 Column Adapters
Marking the Rack and Attaching Cage Nuts
Use this section to mark the front columns and attach the cage nuts to the rear
columns of the Compaq 4000- or 7000-series rack. The column adapters attach to
the front columns and the slides are attached to the column adapters and the cage
nuts to hold the NetServer's slides in place. Use the marking pen to mark the
locations on the columns.
CAUTION If other rack components are to be mounted in the rack below
the HP NetServer, install those components before starting to
mount the NetServer.
