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

System Power LED. This LED glows steadily when the
system is powered up and 12 V system power is
available. This power supply is used to maintain the
battery charge and provide supplementary power to the
cache microcontroller.

Auxiliary Power LED. This LED glows steadily when 3.3V
auxiliary voltage is detected. The auxiliary voltage is
used to preserve BBWC data and is available any time
that the system power cords are connected to a power
supply.

The system is powered down, and the cache contains data that has
not yet been written to the drives. Restore system power as soon as
possible to prevent data loss.

Data preservation time is extended any time that 3.3 V auxiliary
power is available, as indicated by LED 2. In the absence of
auxiliary power, battery power alone preserves the data. A fully­charged battery can normally preserve data for at least two days.

The battery lifetime also depends on the cache module size. For
further information, refer to the controller QuickSpecs on the HP
website (http://www.hp.com

The cache microcontroller is waiting for the host controller to
communicate.

The battery pack is below the minimum charge level and is being
charged. Features that require a battery (such as write cache,
capacity expansion, stripe size migration, and RAID migration) are
temporarily unavailable until charging is complete. The recharge
process takes between 15 minutes and two hours, depending on
the initial capacity of the battery.

The battery pack is fully charged, and posted write data is stored
in the cache.

The battery pack is fully charged, and there is no posted write data
in the cache.

An alternating green and amber blink pattern indicates that the
cache microcontroller is executing from within its boot loader and
receiving new flash code from the host controller.

There is a short circuit across the battery terminals or within the
battery pack. BBWC features are disabled until the battery pack is
replaced. The life expectancy of a battery pack is typically more
than three years.

There is an open circuit across the battery terminals or within the

).

Optimum environment

When installing the server, select a location that meets the environmental standards described in this

section.

Setup 19

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 20

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

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

Memory subsystem architecture

the effect of DIMM slot population, see "General DIMM slot population guidelines (on page 25)."

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.

Hardware options installation 23

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.

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.

• The server supports up to 16 GB (4 x 4-GB) for Unbuffered Memory configurations.

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 Registered 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.

• Heaviest load (DIMM with most ranks) within a channel goes furthest from the CPU.

• Non-ECC DIMMs are not supported

• Each channel supports up to two Unbuffered DIMMs.

• When using UDIMMs, use ECC only.

• When possible, balance the loads per channel.

• 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 DIMMs, the quad-rank DIMM must be installed first on that channel.

• 256MB technology, x4 DRAM on UDIMMs and quad-rank UDIMMs are not supported.

• Always use HP qualified DIMMs.

Populate the DIMM slots in the following sequence:

• DIMM 3A and DIMM 6B

• DIMM 2C and DIMM 5D

• DIMM1E and DIMM 4F

CAUTION: Always observe the guidelines in this document. Failure to follow these guidelines

can cause hardware damage or halt data access.

When installing or replacing a TPM, observe the following guidelines:

• Do not remove an installed TPM. Once installed, the TPM becomes a permanent part of the system

board.

• When installing or replacing hardware, HP service providers cannot enable the TPM or the

encryption technology. For security reasons, only the customer can enable these features.

).

• When returning a system board for service replacement, do not remove the TPM from the system

board. When requested, HP Service provides a TPM with the spare system board.

• Any attempt to remove an installed TPM from the system board breaks or disfigures the TPM security

rivet. Upon locating a broken or disfigured rivet on an installed TPM, administrators should consider
the system compromised and take appropriate measures to ensure the integrity of the system data.

• When using BitLocker™, always retain the recovery key/password. The recovery key/password is

required to enter Recovery Mode after BitLocker™ detects a possible compromise of system integrity.

• HP is not liable for blocked data access caused by improper TPM use. For operating instructions, see

the encryption technology feature documentation provided by the operating system.

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic
devices, including computers, generate RF energy incidental to their intended function and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into two classes, A
and B, depending upon their intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment. Class B devices are those that may
reasonably be expected to be installed in a residential environment (for example, personal computers).
The FCC requires devices in both classes to bear a label indicating the interference potential of the device
as well as additional operating instructions for the user.

Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to 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.

To prevent electrostatic damage:

• 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 to prevent electrostatic
discharge

Several methods are used 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 ±10 percent resistance in the ground cords.
To provide proper ground, 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.

• Use conductive field service tools.

• 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 an authorized reseller
install the part.

For more information on static electricity or assistance with product installation, contact an authorized
reseller.
