least two people are needed to safely unload the rack from the pallet. An empty
42U rack weighs 115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become
unstable when being moved on its casters. Do not stand in front of the rack as it
rolls down the ramp from the pallet, but handle it from the sides.
WARNING: To reduce the risk of personal injury or damage to the equipment,
be sure that:
■ The leveling jacks are extended to the floor.
■ The full weight of the rack rests on the leveling jacks.
■ The stabilizing feet are attached to the rack if it is a single-rack
installation.
■ The racks are coupled together in multiple-rack installations.
■ Only one component is extended at a time. A rack may become unstable if
more than one component is extended for any reason.
Server Warnings and Precautions
Before beginning these procedures, read and understand the following
statements.
WARNING: To avoid the risk of personal injury or damage to the equipment, a
minimum of two people MUST lift the server into the rack. The server weighs
about 27.24 kg (60 lb). If the unit is to be loaded above chest level, a third
person must assist in aligning the rails while the other two support the unit.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the
hot-plug drives and internal system components to cool before touching them.
Page 27
Rack Installation 2-3
WARNING: This equipment is designed for connection to a grounded (earthed)
AC outlet. The grounding-type plug is an important safety feature. To avoid risk
of electric shock or damage to your equipment, do not disable this feature.
CAUTION: The rack-mountable ProLiant ML350 Generation 2 server
always be operated with the access panel on. Proper cooling cannot be
achieved if the access panel is removed.
Optimum Environment
When installing your ProLiant ML350 Generation 2 server into a rack, the
following requirements must be met:
■ Space
■ Power

Page 28
2-4 Compaq ProLiant ML350 Generation 2 Tower-to-Rack Conversion Guide
Power Requirements
WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power to
the rack. Consult the electric authority having jurisdiction over your facility
wiring and installation requirements.
The installation of this equipment shall be in accordance with local/regional
electric regulations governing the installation of information technology
equipment by licensed electricians. This equipment is designed to operate in
installations covered by NFPA 70-1999 (National Electric Code) and
NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing
Equipment). For electric power ratings on options, refer to the product rating
label or user documentation supplied with that option.
When installing more than one server, it may be necessary to utilize additional
power distribution devices to safely provide power to all devices.
■ Balance the power load between available AC supply branch circuits.
■ The overall system AC current load must not exceed 80 percent of the
AC supply branch circuit current rating.
Grounding Requirements
To ensure proper operation and safety, the server must be properly grounded
(earthed). In the United States, install the equipment in accordance with NFPA
70-1999 (National Electric Code) Article 250 as well as any local and regional
building codes. In Canada, install the equipment in accordance with Canadian
Standards Association, CSA C22.1, Canadian Electric Code. In all other
countries, follow any regional or national electric wiring codes such as the
International Electrotechnical Commission (IEC) 364 parts 1 through 7.
Furthermore, you must ensure that all power distribution devices used in the
installation—such as branch wiring and receptacles—are Listed or Certified
grounding-type devices.
Because of the high ground-leakage currents associated with multiple servers
connected to the same power source, Compaq recommends the use of a power
distribution unit (PDU) that is either permanently wired to the building branch
circuit or is provided with a nondetachable cord that is wired to an
industrial-style plug. NEMA locking-style plugs or those complying with IEC
60309 are considered suitable for this purpose. Compaq does not recommend
using common power outlet strips for this equipment.
Page 29
Temperature Requirements
To ensure continued safe and reliable operation of the equipment, install or
place the system in a well-ventilated, climate-controlled environment.
The Compaq Maximum Recommended Ambient Operating Temperature
(TMRA) for most server products is 35°C (95°F). The temperature in the room
where the rack is located should not exceed
The operating temperature inside the rack is always higher than the room
temperature and is dependent on the configuration of equipment in your rack.
The TMRA for each piece of equipment should be checked before installation.
The maximum internal rack temperature for your configuration should not
exceed the values shown in the following table.
Internal Rack Temperature Maximums
Equipment Included Internal Rack Temperature Maximum
Rack-mountable ProLiant servers 47°C/122°F
Compaq rack-mountable options 40°C/104°F
Other manufacturer options See other manufacturer specifications
Rack Installation 2-5
35°C (95°F).
Table 2-1
CAUTION: To reduce the risk of damage to the equipment when installing
third-party options:
■ Make sure that the option equipment does not impede airflow to the
rack-mountable ProLiant servers or increase the internal rack temperature
beyond the maximum rating specified by Compaq.
■ Make sure that the Manufacturer Maximum Recommended Ambient
Operating Temperature of the option equipment is not exceeded when
installed into the rack.
Page 30
2-6 Compaq ProLiant ML350 Generation 2 Tower-to-Rack Conversion Guide
Airflow Requirements
The ProLiant ML350 Generation 2 server draws cool air in through the front
of the chassis and exhausts warm air out through the rear of the chassis.
Therefore, the front of the rack must be adequately ventilated to allow ambient
room air to enter the cabinet, and the rear door must be adequately ventilated
to allow the warm air to escape from the cabinet.
IMPORTANT: Do not block the ventilation openings.
When there is any vertical space in the rack not filled by a server or rack
component, the gaps between the components cause changes in airflow
through the rack and across the servers. Cover all gaps with blanking panels to
maintain proper airflow.
CAUTION: Always use blanking panels to fill empty vertical spaces in the rack.
This arrangement ensures proper airflow. Using a rack without blanking panels
results in improper cooling that can lead to thermal damage.
Compaq 9000 Series racks provide proper server cooling from flow-through
perforations, ensuring 64 percent open area for ventilation. Refer to the
documentation provided with Compaq 7000 Series racks for guidelines on
meeting airflow requirements.
CAUTION: When using a Compaq 7000 Series rack, you must install the
high-airflow rack door insert [Part Number 327281-B21 (42U) and Part Number
157847-B21 (22U)] to provide proper front-to-back airflow and cooling and
prevent damage to the equipment.
Securing the Mounting Hardware to the Server and Rack
Securing the mounting brackets and slide rail assemblies consists of the
following:
■ Marking the server rack position with the template
■ Installing cage nuts into the rack frame
■ Securing the slide rail to the mounting bracket
■ Installing the mounting bracket slide assembly onto the rack
Page 31
Marking with the Template
A template is provided to mark the rack for cage nut and mounting bracket
positions. Starting at the bottom of the rack or at the top of a previously

Installing the Cable Management Arm
The cable management arm secures to the cable management arm bracket that
was previously installed. See “Installing the Cable Management Arm Bracket”
in Chapter 1. All cables running to and from the server are tied to this arm.
The cable management arm allows the cables to swing out of the way when
the server is accessed.
To install the cable management arm, follow these steps:
1. Slide the server into the rack. See “Installing the Server into the Rack”
earlier in this chapter.
2. Secure one end of the cable management arm to the cable management
arm bracket on the server using two M6 x 1.0-12L Phillips screws
(supplied).

Cabling the Server
After the cable management arm is installed, cable the server by following
these procedures:
1. Plug all external cables into the server.
2. If you installed a switchbox into the rack, route the CPU-to-switchbox
cables to the switchbox.
3. Bundle all of the cables, including the power cable, and then secure
them to the cable management arm using the tiewraps (supplied).

Electrostatic Discharge Information
To prevent damaging the system, be aware of the precautions you must follow
when setting up the system or handling parts. A discharge of static electricity
from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of
the device.
Preventing Electrostatic Discharge
To prevent electrostatic damage, observe the following precautions:
■ Avoid hand contact by transporting and storing products in static-safe
containers.
■ Keep electrostatic-sensitive parts in their containers until they arrive at
static-free workstations.
■ Place parts on a grounded surface before removing them from their
containers.
■ Avoid touching pins, leads, or circuitry.
■ Always be properly grounded when touching a static-sensitive
component or assembly.

Grounding Methods
There are several methods for grounding. Use one or more of the following
methods when handling or installing electrostatic-sensitive parts:
■ Use a wrist strap connected by a ground cord to a grounded workstation
or computer chassis. Wrist straps are flexible straps with a minimum of
1 megohm
proper grounding, wear the strap snug against the skin.
■ Use heel straps, toe straps, or boot straps at standing workstations. Wear
the straps on both feet when standing on conductive floors or dissipating
floor mats.
■ Useconductivefieldservicetools.
■ Use a portable field service kit with a folding static-dissipating
work mat.
If you do not have any of the suggested equipment for proper grounding, have
a Compaq authorized reseller install the part.
NOTE: For more information on static electricity, or assistance with product installation,
contact your Compaq authorized reseller.
