Safety Warnings:
WARNING This product has not been evaluated for connection to an IT power
system (an ac distribution system having no direct connection to
earth according to IEC 950).

Preface-iv
LEAKAGE CURRENT:
WARNING Due to the types of products able to be installed in this product there
is a risk of high leakage current (>3.5 mA). Reliable ground circuit
continuity is vital for safe operation of this product. To reduce the
risk of electric shock, earth connection is essential before connecting
the supply. Never operate product with the ground conductor
disconnected.
POWER LIMITATIONS:
WARNING IMPORTANT SAFETY NOTE FOR INSTALLATION
For installing cabinets containing switchless Power Distribution
Units (PDU part numbers C2785-63004, C2786-63008, C2786-63009 or
C2786-63010):
The socket outlet shall be installed near the rack cabinet and shall
be easily accessible, because the plug on the power supply cord is
intended to serve as the disconnect device for this cabinet.
The Total output current rating of the PDU equals the output
current rating of the UPS receptacle to which the PDU is connected
(up to 16 Amps maximum). Check the total input current ratings of
the equipment installed in the cabinet to avoid overloading the UPS.
WARNING IMPORTANT SAFETY NOTE FOR INSTALLATION
For installing dual-voltage-range-rated Power Distribution Units
(PDU part numbers C2785-63004 or C2786-63008) for connection to an
Uniterruptable Power Supply (UPS):
The voltage of the PDU receptacles equals the voltage of the UPS
receptacle to which the PDU is connected (200-240V range). CHECK
THE UPS OUTPUT VOLTAGE BEFORE CONNECTING ANY
EUIPMENT TO THE PDU! Failure to check the voltage could lead to
severe equipment damage.
CAUTION To reduce the risk of overload, do not load any single PDU with more than a
maximum of 16 Amperes. In addition, do not load a single NEMA 5-15
receptacle with more than 15 Amperes and any single IEC 320 receptacle
with more than 10 Amperes.
ACCESSORIES:
CAUTION This product has been designed to be used with specific electrical accessories
(i.e. PDU's). The use of any other accessory is not recommended or supported.

Preface
This edition of the Cabinet Installation Guide contains technical information about

Introduction
Inspecting the Shipment
1Introduction
The HP 9000 D2xx and D3xx Class Enterprise servers can be mounted into a cabinet to
consolidate the pieces of the core system. The cabinet is available in a 1.6 meter (63.8
inches) size. The cabinet is offered as a factory integrated cabinet (A3764A) with one to
four D Class computers mounted, or a field integrated (A3765A) cabinet with no computers
mounted by the factory. Both cabinets have a usable depth of 0.905 meter (35.6 inches).
The cabinets have mounting columns that comply with EIA standard 23 inch mounting
flanges.
Inspecting the Shipment
When the shipment arrives, make sure the cabinet has been received as specified by the
carrier's bill of lading. Inspect the shipping container for evidence of mishandling during
transit. If the container is damaged or water-stained, ask that the carrier's agent be
present when the cabinet is unpacked. Refer to the instructions described in the Claims
Procedure section. If everything appears to be in satisfactory condition, proceed with the
unpacking instructions.
NOTE Do not discard or destroy the shipping container or the packaging material. If
it becomes necessary to repackage the cabinet, these items will be needed. HP
also suggests that you keep this manual, in case you later have to repackage
the cabinet for shipment.
Claims Procedure
If the shipment is incomplete or if the equipment is damaged or fails to meet specifications,
notify the nearest Hewlett-Packard Sales and Support Office. If damage occurred in
transit, notify the carrier as well. Hewlett-Packard will arrange for replacement or repair
without waiting for settlement of claims against the carrier. If the shipment was damaged
in transit, keep the shipping containers and packaging material for inspection.

Cabinet Configurations
Cabinet Configurations
Although the cabinets are designed to accommodate a variety of components mounted in
just about any configuration, there are some basic rules that apply to mounting a computer
system. These rules allow for weight distribution, accessibility of the components, and
cable management inside the rack-mount cabinet. Figure 1-1 shows the available
configurations.

Required Tools
Required Tools
Before beginning the installation process, make sure you have the necessary tools.
1. Standard hand tools (including Torx-drive set and voltmeter).
2. Flat-blade screwdriver, 3/16-inch by 9 inches long.
3. Open-ended 9/16-inch wrench.
Installation Site Requirements
Before proceeding with the installation of the A3764A or A3765A rack mount cabinet,
ensure that all the procedures and requirements listed in the Site Preparation Guide
(A3764-90005) have been completed. If all requirements and procedures have not been
completed, do not proceed with the installation procedures listed in this document.
Refer to the Site Preparation Guide to establish responsibility for the task that needs to be

Unpacking and Installation
Unpacking the Cabinet Assembly
2Unpacking and Installation
This chapter describes how to unpack the A3764A or A3765A cabinet assembly. Both
cabinets are shipped on a pallet. The instructions for unpacking are the same for both the
A3764A and A3765A cabinet.
It is the customer's responsibility to inspect the shipping package for shipping damage. It
is not the customers responsibility to remove the cabinet assembly from the shipping
pallet.
NOTE Do not discard or destroy the shipping container or the packaging material. If
it becomes necessary to repackage the cabinet, these items will be needed. HP
also suggests that you keep this manual, in case you later have to repackage
the cabinet for shipment.
Unpacking the Cabinet Assembly
All cabinet types are packaged the same way. Be sure to read the unpacking instructions
before proceeding.
WARNING A fully configured 1.6 meter cabinet (A1897A) can weight up to
approximately 441 kg (980 lbs). Be very careful when unpacking the
cabinet.
To unpack an A series cabinet, perform the following steps:
1. Cut the plastic polystrap bands around the shipping container.
WARNING Wear protective glasses while cutting the plastic bands around the
shipping container. These bands are under tension. When cut, they
can spring back and cause serious eye injury.
2. Lift the cardboard top cap off of the shipping box. See Figure 2-1.
