NMI functionality
An NMI crash dump enables administrators to create crash dump files when a system is hung and is not
responding to traditional debug mechanisms.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as hangs in
operating systems, device drivers, and applications. Many crashes freeze a system, and the only
available action for administrators is to cycle the system power. Resetting the system erases any
information that could support problem analysis, but the NMI feature preserves that information by
performing a memory dump before a hard reset.
To force the OS to invoke the NMI handler and generate a crash dump log, the administrator can do any
of the following:
• Short the NMI jumper pins
• Press the NMI switch
• Use the Lights-Out 100 Virtual NMI feature

When installing the server, select a location that meets the environmental standards described in this
section.
Setup 17
Space and airflow requirements
Tower server
In a tower configuration, leave at least a 7.6-cm (3-in) clearance space at the front and back of the server
for proper ventilation.
Rack server
To allow for servicing and adequate airflow, observe the following space and airflow requirements when
deciding where to install a rack:
• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another
rack or row of racks.
HP servers draw in cool air through the front door and expel warm air through the rear door. Therefore,
the front and rear rack doors 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.
CAUTION: To prevent improper cooling and damage to the equipment, do not block the
When vertical space in the rack is 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.
The 9000 and 10000 Series Racks provide proper server cooling from flow-through perforations in the
front and rear doors that provide 64 percent open area for ventilation.
ventilation openings.
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.
CAUTION: When using a Compaq branded 7000 Series rack, you must install the high
airflow rack door insert [P/N 327281-B21 (42U) or P/N 157847-B21 (22U)] to provide
proper front-to-back airflow and cooling.
CAUTION: If a third-party rack is used, observe the following additional requirements to
ensure adequate airflow and to prevent damage to the equipment:
• Front and rear doors—If the 42U rack includes closing front and rear doors, you must
allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit
adequate airflow (equivalent to the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the side panels of the rack
must be a minimum of 7 cm (2.75 in).
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the system in a wellventilated, climate-controlled environment.
Setup 18
The 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 must not exceed 35°C (95°F).
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
• Do not permit optional equipment to impede airflow around the server or to increase the
internal rack temperature beyond the maximum allowable limits.
• Do not exceed the manufacturer’s TMRA.
Power requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of information technology equipment by licensed electricians. This equipment is designed to
operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992
(code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on
options, refer to the product rating label or the user documentation supplied with that option.
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 electrical
When installing more than one server, you may need to use additional power distribution devices to
safely provide power to all devices. Observe the following guidelines:
authority having jurisdiction over wiring and installation requirements of your facility.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from
damage caused by power surges and voltage spikes and keeps the system in operation
during a power failure.
• Balance the server power load between available AC supply branch circuits.
• Do not allow the overall system AC current load to exceed 80 percent of the branch circuit AC
current rating.
• Do not use common power outlet strips for this equipment.
• Provide a separate electrical circuit for the server.
Electrical grounding requirements
The server must be grounded properly for proper operation and safety. In the United States, you must
install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250,
as well as any local and regional building codes. In Canada, you must install the equipment in
accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other
countries, you must install the equipment in accordance with any regional or national electrical wiring
codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore, you must be sure 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, HP recommends the use of a PDU that is either permanently wired to the building’s branch
circuit or includes 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. Using common power outlet
strips for the server is not recommended.

Rack warnings
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.
WARNING: To reduce the risk of personal injury or equipment damage when unloading a
rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U
rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and
may become unstable when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always
handle the rack from both sides.

Hardware options installation
Introduction
If more than one option is being installed, read the installation instructions for all the hardware options
and identify similar steps to streamline the installation process.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before
beginning any installation procedure. Improper grounding can cause electrostatic discharge.
Memory options
IMPORTANT: This server does not support mixing RDIMMs and UDIMMs. Attempting to mix
these two types causes the server to halt during BIOS initialization.
The memory subsystem in this server can support RDIMMs or UDIMMs. Both types are referred to as
DIMMs when the information applies to both types. When specified as RDIMM or UDIMM, the
information applies to that type only. All memory installed in the server must be the same type.
The server supports the following DIMM speeds:
• Single- and dual-rank PC3-10600 (DDR-1333) DIMMs operating at 1333 and 1066 MHz
• Quad-rank PC3-8500 (DDR-1067) DIMMs operating at 1066 MHz
Depending on the processor model, the number of DIMMs installed, and whether UDIMMs or RDIMMs
are installed, the memory clock speed may be reduced to 1066 or 800 MHz. For more information on
the effect of DIMM slot population, see "
Memory subsystem architecture
The memory subsystem in this server is divided into channels. The processor supports two channels, and
each channel supports three DIMM slots, as shown in the following table.

DIMM slots in this server are identified by number and by letter. Letters identify the slots to populate for
specific AMP modes. Slot numbers are reported by ROM messages during boot and for error reporting.
Single-, dual-, and quad-rank DIMMs
To understand and configure memory protection modes properly, an understanding of single-, dual-, and
quad-rank DIMMs is helpful. Some DIMM configuration requirements are based on these classifications.
A single-rank DIMM has one set of memory chips that is accessed while writing to or reading from the
memory. A dual-rank DIMM is similar to having two single-rank DIMMs on the same module, with only
one rank accessible at a time. A quad-rank DIMM is, effectively, two dual-rank DIMMs on the same
module. Only one rank is accessible at a time. The server memory control subsystem selects the proper
rank within the DIMM when writing to or reading from the DIMM.
Dual- and quad-rank DIMMs provide the greatest capacity with the existing memory technology. For
example, if current DRAM technology supports 2-GB single-rank DIMMs, a dual-rank DIMM would be 4GB, and a quad-rank DIMM would be 8-GB.
DIMM identification
IMPORTANT: This server does not support mixing RDIMMs and UDIMMs. Attempting to mix
The memory subsystem may be populated with either RDIMMs or UDIMMs, but mixing the two types is not
supported. To determine DIMM characteristics, use the label attached to the DIMM and the following
illustration and table.
these two types causes the server to halt during BIOS initialization.

General DIMM slot population guidelines
• The HP ProLiant DL120 G6 Server has six memory slots.
• There are two channels per server with three DIMM slot per channel.
• Memory channel 1 consists of the three (3) DIMMs that are closest to the processor
• Memory channel 2 consists of the three (3) DIMMs that are furthest from the processor
• Different types of processors have different types of memory support.
• The server supports up to 12 GB (6 x 2-GB) for Registered Memory configurations.
• ory configurations.
The server supports up to 8 GB (4 x 2-GB) for Unbuffered Mem
Observe the following guidelines when installing DIMMs:
• Do not mix Unbuffered and Registered
PC3 DIMMs.
• Do not mix DIMMs of varying speeds.
• Do not mix DIMMs of varying voltages.
• Do not mix Unbuffered memory (UDIMMs) with Regist
ered memory (RDIMMs).
• Do not install DIMMs if the processor is not installed.
• Populate DIMMs from heaviest load (double-rank) to lightest load (single-rank) within

a channel.
• Non-ECC DIMMs are not supported
• Each channel supports up to two Unbuffered DIMMs.
• When using UDIMMs, use ECC only.
• s per channel.
When possible, balance the load
• If quad-rank DIMMs are installed for the processor, a maximum of two DIMMs can be installed on
each channel for that processor.
• If a channel contains quad-rank DI
MMs, the quad-rank DIMM must be installed first on that channel.

Hard drive guidelines
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all drive numbers.
• If only one hard drive is used, install it in the bay with the lowest drive number.
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
Optional storage controllers provide support for hot-plug capability and drive LEDs. Controller options
are:
• The embedded controller supports non-hot-plug SATA hard drives. Drive LEDs are not supported.
• Optional SATA controllers support hot-plug SATA hard drives and drive LEDs.
• Optional SAS controllers support hot-plug SAS or SATA hard drives and drive LEDs.
