Compaq ProLiant
Use this white paper in conjunction with documents for the
ProLiant DL380 Generation 2 server and Compaq rack deployment
products. This paper is intended for Field Systems Engineers (FSEs)
and customers (IT managers, system managers, account managers,

Executive Summary

Many business enterprises and service providers use network
infrastructure and web applications that work best on dedicated
servers. This creates the need to fit a large number of smaller servers
into existing server rooms and data centers. Compaq meets this need
with the density-optimized line of ProLiant servers such as the
ProLiant DL380 Generation 2 server. At a height of 2U each, up to
21 ProLiant DL380 Generation 2 servers can fit in a single Compaq
42U rack. While the ProLiant DL380 Generation 2 server has clear
space saving benefits, its compressed size presents new challenges
for rapid server deployment, as well as cable management and
environmental considerations.

DL380 Generation 2 servers in a Compaq rack.

Compaq engineers have developed innovations in rapid high-volume
deployment and improved cable management for large installations
of ProLiant DL380 Generation 2 servers. This white paper
introduces planning, power and thermal considerations, server and
rack requirements, and installation configurations. It also outlines the
products associated with high-volume deployment in Compaq rack
configurations.

IMPORTANT: This document discusses only the ProLiant DL380
Generation 2 server, the Compaq 7000- and 9000-series racks, and
related Compaq rack options. This document does not discuss other
Compaq servers or products or racks not manufactured by Compaq.

Server Warnings

Adhere to the following guidelines when servicing or installing a Compaq server:

WARNING: To reduce the risk of electrical shock or damage to the equipment:

• Unplug the power cord from the system.

• Do not disable the power-cord grounding plug. The grounding plug is an important

safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible
at all times.

CAUTION: To properly ventilate the system, provide at least 7.6 cm (3 inches) of
clearance at the front and back of the computer.

CAUTION: The system is designed to be electrically grounded. To ensure proper
operation, plug the AC power cord only into a properly grounded (earthed) AC outlet.

Rack Warnings

WARNING: To reduce the risk of personal injury or damage to the equipment:

• Do not attempt to move or relocate an equipment rack populated with servers. A fully
populated rack can weigh as much as 771 kg (1,700 lb). The rack may become
unstable and cause serious personal injury or equipment damage.

• Before installing the servers, extend the leveling jacks to the floor and rest the full
weight of the rack on the leveling jacks. Either install the stabilizer kit or couple
multiple racks together for stability.

• Always load the heaviest item first, and load the rack from the bottom to the top.
Loading in this manner makes the rack “bottom-heavy” and helps prevent the rack
from becoming unstable.

• Extend only one ProLiant DL380 Generation 2 server at a time. A rack may become
unstable if more than one ProLiant DL380 Generation 2 server is fully extended for
any reason.

CAUTION: Do not overload the AC supply branch circuit that provides power to the
rack.

Introduction

Compaq designed the dense ProLiant DL380 Generation 2 server to meet the challenges
associated with deploying a high concentration of servers in a single rack. Compaq suggests that
customers evaluate their environments, power distribution, console, cable, and thermal
management choices well in advance to ensure the efficient deployment of multiple

ProLiant DL380 Generation 2 servers in a rack. Use this document, in conjunction with the
documents listed in Appendix A,

as a guideline for planning rack configurations for high-volume

deployments of ProLiant DL380 Generation 2 servers.

The “Power Distribution Units” section outlines Compaq PDU choices best suited for building
rack configurations. This section provides technical specifications for high- and low-voltage
PDUs. It also describes how to allocate the correct number and type of PDUs for specific rack
deployments.

The “Planning Rack Configurations” section provides weight information for individual rack
components to help address floor support requirements. It also describes cable systems.

The “Console Management Systems” section provides information on server management
options.

All discussions of power requirements for ProLiant DL380 Generation 2 servers are based on the
input power of the server. This document uses the maximum rated power supply input of 575 W
for calculation purposes. However, derating the input power may be effective to:

• Minimize the number of PDUs required for each rack.

• Match the rack current requirements with the existing circuit breaker capacity.

• Match the rack cooling requirements with the existing facility cooling capability.

For more information about input power derating, see Appendix C.

IMPORTANT: In this document, derating the input power budget means using less than the
maximum rated input power values for the power supply. To derate the input power, see
Appendix C. Compaq strongly recommends that the derated power budget satisfies all the
installation requirements, including future upgrade plans.

Refer to the Compaq ProLiant DL380 Generation 2 Server QuickSpecs for detailed specifications
and options for the ProLiant DL380 Generation 2 server.

In Compaq 7000- and 9000-series racks, the 295363-xxx PDU series must be installed vertically
in the rack side panels to prevent interference with the server rack rails. Compaq Vertical-Mount
PDU Bracket kits enable PDUs to be mounted vertically in the side compartments of 7000- and
9000-series racks. Compaq offers two Vertical-Mount PDU Bracket kits:

• Compaq Vertical-Mount PDU Bracket (P/N 191265-B21): This kit includes eight brackets
that support four PDUs. This kit works best with low-voltage applications that use the power
cord included with the server.

• Compaq Vertical-Mount PDU Bracket with High-Voltage Cables (P/N 166097-B21): This kit
includes 11 Y-cables and 4 brackets that support 2 PDUs. This kit works best with high­voltage, high-current PDUs. Using the Y-cables enables each power outlet on the PDU to
supply power for 2 servers.

Figuring Type and Number of PDUs

The type and number of PDUs required to power a full rack of servers depends on each server’s
power requirement, the number of servers deployed in the rack, and the available power for the
servers.

Compaq PDUs support both high-voltage and low-voltage applications. The input current rating
for a ProLiant DL380 Generation 2 server is either 3.2 A at 200 to 240 volts or 6.4 A at 100 to
120 volts. To determine the number of servers supported by a PDU, divide the PDU’s current
rating by the server’s total input current rating.

IMPORTANT: The examples shown in the following sections use the maximum rating of the
power supply. They are for reference only.

Non-Redundant Power

The following examples illustrate how to calculate the number of servers per PDU when using
non-redundant power.

Example

One high-voltage PDU (P/N 207590-D72) has a current rating of 24 A. The server has a total
input current rating of 3.2 A at 200 volts.

24 A (PDU current rating) / 3.2 A (server total input current rating) = 7

This PDU can support a maximum of 7 servers at full server input current ratings.

Example

One low-voltage PDU (P/N 207590-D71) has a current rating of 24 A. The server has a total
input current rating of 6 A at 100 volts.

24 A (PDU current rating) / 6.4 A (server total input current rating) = 3

This PDU can support a maximum of 3 servers at full server input current ratings.

Redundant Power

The ProLiant DL380 Generation 2 server supports a redundant power supply. The power supply
for this server automatically senses input voltage level.

When using redundant power, it is necessary to use two PDUs per server. The following
examples illustrate how to calculate the number of servers per pair of PDUs when using
redundant power.

Example

Two high-voltage PDUs (P/N 207590-D72) have a combined current rating of 48 A. The
server has a total input current rating of 3 A at 200 volts (redundant power).

2 [24 A (PDU current rating) / 3.2 A (server total input current rating)] = 7

These PDUs can support a maximum of 7 servers at full server input current ratings.

Example

Two low-voltage PDUs (P/N 207590-D71) have a current rating of 48 A. The server has a
total input current rating of 6 A at 100 volts (redundant power).

For more information on low-voltage PDUs, refer to the “Power Distribution Unit Low-Voltage
Models for North America and International Use” website:

www.compaq.com/products/servers

Selecting Server Power Cords

The appropriate server power cord to use depends on the cable management system installed in
the rack. Generally, the sliding rail cable management system requires a power cord that is

1.8288 m (6 ft) in length. This length provides enough slack for the power cord to route through

the cable management arm.

High-Voltage Y-Cables

The Vertical-Mount PDU Bracket with High-Voltage Cables kit includes 11 Y-cables, each of
which is 3.0 m (10 ft) long. The single-cord PDU section is 1.8 m (6 ft) long, and the dual-cord
server section is 1.3 m (4 ft) long. See Table 7 for part numbers.

Y-cables have a single-cord section with an IEC connector that connects to the PDU, a dividing
joint in the center, and a dual-cord section with IEC connectors that connect to the servers. One
Y-cable supplies power from the PDU to two ProLiant DL380 Generation 2 servers in the
standard configuration or one ProLiant DL380 Generation 2 server in the maximum
configuration.

CAUTION: When installing server power cords into the PDUs, ensure that the load is
balanced among the output circuit breakers. Do not exceed the ratings of the circuit
breakers.

In-Rack Local Consoles

With an in-rack local console, all equipment, servers, switchboxes, keyboards, keyboard drawers,
and video displays are installed together in the same rack. One console switchbox can support up
to eight pieces of equipment.

Each server deployed in a fully populated rack with an in-rack local console management system
requires the following accessories for successful deployment and operation:

• Rack Rail kit (standard rack rails and cable management arm, Telco rack solution, or
third-party rack cabinet and cable management arm )

• KVM server to console cables [1.8 m (6 ft) cables for sliding rail solutions]

• One or two RJ-45 cables for NIC 1 and NIC 2

Table 11 outlines the number of devices that fully populate a 42U or 36U rack with an in-rack

Off-Rack Local Consoles

When an off-rack local console is used, certain components such as console switchboxes,
keyboards, and video displays do not populate space in the rack, but are located in close
proximity to the rack. Because of this, the rack can be fully populated with servers. Cable lengths
for connecting servers to an off-rack local console vary in length depending on the location of the
console.

Each server deployed in a fully populated rack with an off-rack console management system
requires the following accessories for successful deployment and operation:

• Rack Rail kit (standard rack rails and cable management arm, Telco rack solution, or third­party rack cabinet and cable management solution)

• KVM server to console cables

• One or two RJ-45 cables for NIC 1 and NIC 2

Remote Console Management

The Compaq Remote Insight Lights-Out Edition board is a PCI-based board that enables server
management by remote access regardless of the state of the host server operating system or the
host CPU. The Remote Insight board sends alerts and performs other functions even if the host
server operating system is not responding. For installation information and features, refer to the

Planning Rack Configurations

Consider several important factors when planning a rack configuration:

• The number of servers deployed in the rack

• The number of other devices such as keyboards, keyboard drawers, video displays, and

console switchboxes that support the servers

• The number of PDUs and their orientation

• The type of rack

• The rack management system

• The console management system

All of these factors influence floor support requirements, future service and upgrade
requirements, and installation requirements.

Table 12 lists the weight and power specifications for Compaq racks and rack option products. To
calculate floor support requirements for a particular rack configuration, add the weight
measurements to calculate the total weight of a rack fully populated with
ProLiant DL380 Generation 2 servers. See the following example:

Special Considerations for 7000-Series Racks

Compaq recommends deploying servers in either a 7000- or 9000-series Compaq rack. 4000­series racks (36U) are not recommended for 2U high-volume deployments with ProLiant
DL380 Generation 2 servers because they are not sturdy enough to support the weight of 18
servers. The 7000- and the 9000-series Compaq racks mentioned in this section are the 7142,
9142, and 9136, racks. This document does not discuss deploying servers in any rack not
manufactured by Compaq.

WARNING: Follow these guidelines to reduce the risk of personal injury or damage to
the equipment:

• Do not install a ProLiant DL380 Generation 2 server into a rack until the rack has
been placed in its final location.

• Pre-install slide rails, PDUs, power cords, and cables into the rack in a build room or
other location before moving the rack to its final location.

• Extend the leveling jacks to the floor and rest the full weight of the rack on the jacks

efore installing any servers. The casters are not designed to support the full weight of

a populated rack.

• Do not move a rack populated with servers. A fully populated rack can weigh up to
1,800 pounds. Moving a populated rack can cause the rack to become unstable,
resulting in serious personal injury or equipment damage.

To effectively cool the ProLiant DL380 Generation 2 servers in a 7000-series rack, replace the
front door of the rack with the High Air Flow Rack-Door Insert before deploying the servers in
the rack. See Table 13 for rack-door insert part numbers.

Compaq strongly recommends using the Compaq Rack Extension kit (P/N 154392-B21) to
alleviate any space problems for cable bundles at the rear of 7000-series racks.

Rack Management Systems

Compaq recommends using the standard rack rails and cable management arm. The rack
management solution installed in the rack determines the position of the PDUs installed in the
rack side panels. To determine the best rack management solution, consider the service and
upgrade demands of the servers deployed in the rack.

IMPORTANT: Read the Compaq Ultra-Dense Server Deployment in Third-party Cabinet
Racks or the Compaq Ultra-Dense Server Deployment in Telco Racks before deploying ProLiant

DL380 Generation 2 servers in a third-party rack or Telco rack.

Standard Rack Rails

The standard rack rails and cable management arm work best with a rack of servers that are
frequently serviced or upgraded. With this solution, a server can be powered down and serviced
without disconnecting the server cables or removing the server from the rack.

The standard rack rails and cable management arm are designed for 29-inch deep, square-hole
racks. The sliding rack rails compress and snap securely in place in the rack without screws or
nuts.

The cable management arm attaches directly onto the rear of the server and the rear of the rack. It
secures and routes the cables along the rear of the rack. This not only prevents the cables from
sagging and tangling, but it also enables proper air ventilation through the rack while enabling the
servers to be fully extended without disconnecting any of the server cables.

The standard rack rails and cable management arm are conducive to in-rack servicing and provide
convenient access to the server cables and connectors. Refer to the Compaq ProLiant DL380
Generation 2 Setup and Installation Guide for complete installation instructions.

Third-Party Rack Cabinet Solution

Because not all customers use Compaq racks, the ProLiant DL380 Generation 2 server design
supports deployment in third-party rack cabinets. Compaq offers a Third-Party Rack Cabinet kit
to use in installing ProLiant DL380 Generation 2 servers in third-party racks. This kit includes
variable length rack rails that are compatible with a variety of third-party racks. The Third-Party
Rack Cabinet kit can be installed in racks that are 610 mm (21 inches) to 740 mm (29.13 inches)
deep.

IMPORTANT: Always install the Compaq Third-Party Rack Cabinet kit when deploying a
ProLiant DL380 Generation 2 server in a third-party rack. The kit supports the same cable
management arm that the standard fixed rack rail solution uses.

Telco Rack Solution

Many data centers use Telco racks. The ProLiant DL380 Generation 2 server design supports
deployment in Telco racks. Compaq offers a Telco Rack kit designed to install ProLiant DL380
Generation 2 servers in Telco racks. This kit includes rack rails and screws that are compatible
with a variety of Telco racks. The Telco rack kit includes replacement server rails designed to fit
on the ProLiant DL380 Generation 2 server. Before deploying ProLiant DL380 Generation 2
servers into a Telco rack, remove the standard server rails and replace them with the Telco server
rails included in the Telco Rack kit.

IMPORTANT: Always install the Compaq Telco Rack kit when deploying a ProLiant DL380
Generation 2 server in a Telco rack.

Installation Procedures

This section describes preparation and basic installation procedures common to various

Generation 2 servers into a third-party rack, refer to the documentation that ships with the third­party rack-mounting kit (P/N 228894-B21).

IMPORTANT: Read the Compaq Ultra-Dense Server Deployment in Third-Party Cabinet
Racks before deploying ProLiant DL380 Generation 2 servers in a third-party rack.

Telco Rack Solution

The Telco Rack kit includes replacement server rails designed to fit on the ProLiant
DL380 Generation 2 server. Before deploying ProLiant DL380 Generation 2 servers into a Telco
rack, remove the standard server rails and replace them with the Telco server rails included in the
Telco Rack kit. For detailed instructions on deploying ProLiant DL380 Generation 2 servers into
a Telco rack, refer to the documentation that ships with the Telco rack-mounting kit (P/N
228892-B21).

IMPORTANT: Read Compaq Ultra-Dense Server Deployment in Third-party Cabinet Racks or
Compaq Ultra-Dense Server Deployment in Telco Racks before deploying ProLiant DL380

Generation 2 servers in a third-party rack or Telco rack.

Installing Power Distribution Units

PDU installation varies depending on the rack configuration, the number of servers deployed in
the rack, the selected type of PDU, and the voltage and current rating for each PDU. The
295363-xxx series of PDUs must be mounted vertically in the side panels of the rack. See the
“Power Distribution Units” section for information about the Vertical-Mount PDU Bracket kits
available from Compaq. The installation card in the Vertical-Mount PDU Bracket kit contains
detailed instructions for installing the Vertical-Mount PDU Brackets on a PDU and in a rack.

Positioning PDUs in 36U and 42U Racks

The position of the PDUs in the rack side panels varies depending on the rack size, the number of
servers deployed in the rack, and the cable management solution. As a rule, install PDUs from the
bottom to the top on the same side of the rack as the cable management arm (viewing the rack
from the front).

Installing PDUs in a 36U or 42U Rack

Before installing PDUs in a 36U or 42U rack, you may need to remove the center support bracket
and center it between the PDUs. Install the PDUs on the same side of the rack as the cable

Routing Power Cords

Use the following general procedures to route server power cords in 36U and 42U racks.

IMPORTANT: When installing server power cords into the PDUs, ensure that the load is
balanced among the output circuit breakers.

High-Voltage Power Cords

To route and connect low-voltage power cords:

IMPORTANT: Route and connect the high-voltage power cord to the PDU after the server is
installed.

1. Connect the power cord to the server and route it through the cable management system with
the other server cables.

2. Route the power cord inside the rear rack support to the PDU.

High-Voltage Y-Cables

To route high-voltage Y-cables:

1. Connect the single-cord section of the Y-cable to the PDU installed on the same side as the
cable management tray.

2. Align the Y-joint with the rear rack support and center it between the rack rails of the two
servers that the Y-cable supports.

3. Use two plastic tie wraps to secure the Y-joint to the rack support.

4. After installing the servers, connect the cables to the servers and route them through the cable
management system with the other server cables.

Low-Voltage Power Cords

To route and connect low-voltage power cords:

IMPORTANT: Route and connect the low-voltage power cord to the PDU after the server is
installed.

1. Connect the power cord to the server first and route it through the cable management system
with the other server cables.

2. Route the power cord inside the rear rack support to the PDU.

IMPORTANT: In 7000-series racks, route the power cables from the servers to the PDUs
through the gap in the rear of the rack rail.

Installing the Rack Rails

The following procedure describes how to install the standard rack rails onto the rack. The rails
are designed to snap in place without screws or nuts.

1. Remove the server rails from the left and right standard rails.

2. Insert the rails into the rack holes.

3. Install the server rails on the chassis.

4. Insert the server into the rack.

5. Install the cable management arm.

6. Cable and power up the server.

Repeat the procedure for any subsequent rack rails. For detailed instructions on installing
standard rack rails, refer to the Compaq ProLiant DL380 Generation 2 Server Setup and

Installation Guide and to the Compaq ProLiant DL380 Generation 2 Hardware Configuration
and Installation Poster.

CAUTION: Always install servers from the bottom of the rack to the top. Installing
servers in this manner provides more stability for the rack and reduces the risk of the rack
tipping over.

IMPORTANT: Before installing the rack rails for the standard rack rails and cable
management arm, remove the server rails from the slide rail assembly. See the “Preparing the
ProLiant DL380 Generation 2 for Rack Installation” section in this paper for more information.

IMPORTANT: Install a ProLiant DL380 Generation 2 server in every U-space from the bottom
to the top for maximum density.

Installing a Server in a Rack

Install ProLiant DL380 Generation 2 servers in the rack from the bottom to the top. Tighten the
thumbscrews on the front of each server to secure the server to the rack. Attach the cable
management arm to the rear of the server and to the rear of the rack.

WARNING: To reduce the risk of serious personal injury, fire, or damage to the
equipment:

• Extend the leveling jacks to the floor and rest the full weight of the rack on the
leveling jacks.

• Either install the stabilizer kit or couple multiple racks together for stability.

• Load the heaviest item first and load the rack from the bottom to the top. Loading the

rack in this manner makes the rack “bottom-heavy” and helps prevent the rack from
becoming unstable.

• Do not overload the AC supply branch circuit that provides power to the rack.

• Extend only one ProLiant DL380 Generation 2 server at a time. A rack may become

unstable if more than one ProLiant DL380 Generation 2 server is fully extended for
any reason.

Connecting Cables

This section discusses connecting and routing cables with different cable management solutions
and different console management solutions.

In-Rack Local Console

To install cables with in-rack local consoles:

1. Connect the cables to each device installed in the rack, working from the bottom to the top.

2. Connect the cables to the bottom piece of equipment.

3. Bundle the cables and route them through the cable management arm.

4. Connect the cables to the console switchbox.

5. Connect the power cord to the PDU. Do not connect the PDU to any power source until all
equipment is fully deployed in the rack.

Refer to Compaq ProLiant DL380 Generation 2 Server Setup and Installation Guide for the
recommended order for connecting cables.

When the cables are properly connected and routed through the cable management arm, the rear
door of the rack closes easily over the cables. If the rear door does not close easily, additional
space may be required. Install the rack extension or the bustle kit to provide more space for the
cables at the rear of the rack.

WARNING: To reduce the risk of electrical shock or damage to the equipment:

• Unplug the power cord from the system.

• Do not disable the power-cord-grounding plug. The grounding plug is an important

safety feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible
at all times.

• Do not route the power cord where it can be walked on or pinched by items placed
against it. Pay particular attention to the plug, electrical outlet, and the point where the
cord extends from the server.

IMPORTANT: In 7000-series racks, route the power cables from the servers to the PDUs
through the gap in the rear of the rack rail.

Off-Rack Local Console

Use the in-rack local console procedure for the cable management arm installed in the rack to
connect and route cables with an off-rack local console. Longer cables may be required to reach
an off-rack console. See Table 11 for information on CPU-to-switchbox cables available from
Compaq.

14UH-0701A-WWEN

Appendix C – Power and Thermal
Budgeting

This appendix provides the information and worksheets necessary to calculate power and thermal
budgeting for your system. However, for the most accurate, updated power and thermal budgeting
calculations for your particular configuration, Compaq recommends using the online power
calculator. To use the calculator, visit the Compaq Active Answers website:

activeanswers.compaq.com/aaconfiguratorcode/configurationUi.asp?HTMLFilename=Country

Note: In this document, derating the input power budget means using less than the maximum
rated input power values for the power supply. Verify that the derated power budget satisfies

all the installation requirements including future upgrade plans.

Use either of the following methods to determine the lower input power requirement for
ProLiant DL380 Generation 2 servers:

• Use the derated input power. Calculate this value by using the supplied worksheet at the end
of this appendix.

• Use the allocated input power. Calculate this value by dividing the maximum power of a
PDU by the number of servers. This calculated power must be at least 421 W to support all
the optional components initially released with the ProLiant DL380 Generation 2 server.

Table 17 demonstrates how calculating the derated input power of the system can significantly
reduce input current and thermal dissipation.

Table 17. Derated Current and Thermal Dissipation for Reduced Input Power Assumptions

Input Power Derated Fully Rated

226 W 421 W 575 W

Input Current @115 VAC 2.0 A 3.8 A 6.4 A

Input Current @220 VAC 1.0 A 1.9 A 3.2 A

Thermal Dissipation 770 BTUs/hour 1435 BTUs/hour 1961 BTUs/hour

The derated input power values of 226 W and 421 W can be correlated with the measured input
power values for the minimum and maximum configurations of
ProLiant DL380 Generation 2 servers and optional components outlined in this paper. However,
the derated input power value must be high enough to account for any future upgrades.

Carefully derating the input power may satisfy deployment needs and reduce the number of PDUs
per rack.

Input Current and Thermal Dissipation Calculations

The input power is necessary for determining the input current and thermal dissipation. For a
given input power, the input current varies depending on the input voltage level.

The relationship among the current, the voltage, and the power for the power supply input is as
follows:

Input Current = Input Power / Input Voltage

For example,

Input Current = 100 W /110 V = 0.91 A

Input Current = 100 W /208 V = 0.48 A

The thermal dissipation can be calculated from the input power as follows:

Thermal Dissipation = Input Power

3.41

For example,

Thermal Dissipation = 100 × 3.41 = 341 BTUs/hour

Thermal Dissipation = 200 × 3.41 = 682 BTUs/hour

The easiest way to calculate the thermal dissipation for the entire rack is to add the input power
requirements for all the servers and other units populated in a rack and then multiply the total
input power by 3.41. The total thermal dissipation helps determine cooling and environmental
requirements for the populated rack.

The following section, “Measured Input Power,” further explains the effects on input power and
thermal calculations from adding or removing subsystem components.

Measured Input Power

Table 18 lists the measured input power of the ProLiant DL380 Generation 2 server with varying
subsystem components to illustrate the effects of adding or removing optional components. The

Input Power Budget Derating

This section explains how to derate the input power budget. The maximum rated power supply
input power is 575 W.

To derate the input power, start with the minimum configuration 0 from Table 18. Add the typical
power of the components included in the desired system configuration to calculate the derated
power budget. Typical input powers for various components are listed in Table 19.

Example

Assume the desired server configuration is: 2 × 1.13 GHz, 4 × 128 MB, and 2 × 18.2 GB.

Use Table 20 to calculate the derated power budget using the typical power from Tables 18 and

19.

Table 20. Example Derating Worksheet

Maximum Rated Input Power (in watts) for the base configuration Typical Power 226 W

1. Add the typical power for the processor. 27 W

2. Add the typical power for the memory. 2 W

2 W

3. Add the typical power for the HDD. 10 W

10 W

4. Add the typical power for the PCI card.

Typical power for the desired configuration (in watts) 278 W

5. Calculate the thermal dissipation.

Thermal dissipation for the desired configuration (in BTUs) 947 BTUs/hour

× 3.41

Therefore, the new power budget for this configuration is 278 W (compared to the rated 575 W),
and the thermal dissipation is approximately 947 BTUs/hour (compared to the rated 1961
BTUs/hour).

This derated input power budget significantly reduces the power and thermal requirements for
highly populated racks, which reduces the number of PDUs for certain configurations. Fewer
PDUs increases deployment time and lowers costs. Costs for the facility electrical plumbing, data
center floor ventilation, and facility air conditioning installation can be reduced.

IMPORTANT: Compaq strongly recommends verifying that the derated power budget satisfies
all the installation requirements, including future upgrade plans.

9000-Series Rack Options Compaq Part #

Baying/Coupling kit

Use this kit to join two or more racks to create a multi-bay configuration. The kit supports 24­inch and 600-mm floor tile spacing. Sides of adjacent rack frames are connected, and side
panels are installed on the two ends of the multi-bay configuration.

Stabilizer kit

The anti-tip stabilizer kit provides stability and support when equipment is installed, removed,
or accessed within the rack. Compaq highly recommends using a stabilizer kit with a stand­alone rack.

Ballast kit

The ballast kit provides additional stability and support for the stabilizer kit. Use the ballast kit
if heavy equipment is routinely installed, removed, or accessed within the rack. A ballast kit
must be assembled with a ballast installed on each side of the rack.

Extension Bustle kit

The extension bustle kit attaches to the rear of the rack providing an additional 8.6 cm (3.9 in)
of space to the depth of the rack. This option enables more space for cable management or
extended equipment installed in the rack.
