System maintenance switches

The system maintenance switch (SW1) is an eight-position switch that is reserved. The default position for all eight positions is Off.

The system maintenance switch (SW2) is an eight-position switch that is used for system configuration. The default position for all eight positions is Off.

Position Description Function

S1 iLO 2 security Off = iLO 2 security is enabled

S3 Reserved Reserved S4 Reserved Reserved S5

S7 Reserved Reserved

Configuration lock

Password protection override

Invalid configuration

On = iLO 2 security is disabled Off = System configuration can

be changed On = System configuration is

locked

Off = No function On = Clears power-on

password and administrator password

Off = Normal On = ROM treats system

configuration as invalid

S8 Reserved Reserved

When the system maintenance switch position 6 is set to the On position, the system is prepared to erase all system configuration settings from both CMOS and NVRAM.

CAUTION: Clearing CMOS and/or NVRAM deletes configuration information. Be sure to properly

configure the server or data loss could occur.

Component identification 12

NMI switch

The NMI switch allows administrators to perform a memory dump before performing a hard reset. Crash dump analysis is an essential part of eliminating reliability problems, such as hangs or crashes in operating systems, device drivers, and applications. Many crashes freeze a system, requiring you to do a hard reset. Resetting the system erases any information that would support root cause analysis.

Systems running Microsoft® Windows® operating systems experience a blue screen trap when the operating system crashes. When this happens, Microsoft® recommends that system administrators perform an NMI event by pressing a dump switch. The NMI event enables a hung system to become responsive again.

System LEDs and internal health LED combinations

When the internal health LED on the front panel illuminates either flashing amber or flashing red, the server is experiencing a health event. Combinations of illuminated system LEDs and the internal health LED indicate system status.

NOTE: The system management driver must be installed in order for the internal health LED to provide pre-

failure and warranty conditions.

The front panel health LEDs indicate only the current hardware status. In some situations, HP SIM may report server status differently than the health LEDs because the software tracks additional system attributes.

Memory board LEDs and components

Error indicators remain illuminated when the system is powered off so that the status of the LEDs can still be seen. This matches the behavior of all the other error indicators in the server.

Error indicators will only be cleared if:

• The locking switch is locked after the board is reinstalled

• The system has been rebooted

• The board is removed from the system

CAUTION: When the memory board locking switch is unlocked in a mode that does not support hot-add or

hot-replace capabilities, audio alarms and visual alerts occur. Removing the memory board at this point causes server failure.

• To end the audio alarms and visual alerts, move the memory board locking switch back to the locked

position. This action does not result in data corruption or server failure.

• If removal of a single memory board is required and it is the only memory board, power down the

server and make the necessary memory changes.

the front and rear panels of the server.

4. Press the Power On/Standby button to place the server in standby mode. When the server activates

standby power mode, the system power LED changes to amber.

5. If the server is installed in a rack, locate the server by identifying the illuminated rear UID LED button.

6. Disconnect the power cords.

The system is now without power.

Extend the server from the rack

1. Release the two levers on the lower outside corners of the rack.

NOTE: If the server is in a rack and in the shipping configuration, remove the two shipping screws directly

behind the levers.

IMPORTANT: If the server is installed in a telco rack, remove the server from the rack to access internal

components.

Operations 23

Extend the server on the rack rails until the server rail-release latches engage.

NOTE: The release latches will lock into place when the rails are fully extended.

WARNING: To reduce the risk of personal injury or equipment damage, be sure that the

rack is adequately stabilized before extending a component from the rack.

WARNING: To reduce the risk of personal injury, be careful when pressing the server

rail-release latches and sliding the server into the rack. The sliding rails could pinch your fingers.

3. After performing the installation or maintenance procedure, slide the server back into the rack by

pressing the server rail-release latches.

Operations 24

Unlock and remove the tower bezel

Rack planning resources

The rack resource kit ships with all HP branded or Compaq branded 9000, 10000, and H9 series racks. For more information on the content of each resource, refer to the rack resource kit documentation.

If you intend to deploy and configure multiple servers in a single rack, refer to the white paper on highdensity deployment at the HP website (http://www.hp.com/products/servers/platforms

Optimum environment

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

Space and airflow requirements

section.

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 ventilation

openings.

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.

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.

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.

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.

Setup 29

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.

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 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.

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:

• 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.

Setup 30

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 and cautions

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.

WARNING: When installing a server in a telco rack, be sure that the rack frame is

adequately secured to the top and bottom of the building structure.

WARNING: This server is very heavy. To reduce the risk of personal injury or damage to

the equipment:

• Observe local occupational health and safety requirements and guidelines for manual material handling.

• Get help to lift and stabilize the product during installation or removal, especially when the product is not fastened to the rails. When the server weighs more than 22.5 kg (50 lb), at least two people must lift the server into the rack together. A third person may be required to help align the server if the server is installed higher than chest level.

• Use caution when installing the server in or removing the server from the rack; it is unstable when not fastened to the rails.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and

the internal system components to cool before touching them.

Processor option

The server supports up to four processors. With two or more processors installed, the server supports boot functions through the processor installed in processor socket 1.

Server PPMs provide the proper power to each processor. Each PPM must be installed in the slot adjacent to its processor.

CAUTION: To prevent thermal instability and damage to the server, do not separate the processor from the

heatsink. The processor, heatsink, and retaining clip make up a single assembly.

CAUTION: To prevent possible server malfunction, do not mix processors of different speeds or cache

sizes. Refer to the label on the processor heatsink for a description of the processor.

IMPORTANT: Populate the processors in the following order: 1, 2, 4, 3.

IMPORTANT: If upgrading processor speed or adding additional processors, update the system ROM

before installing the processor.

IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server does not

function.

IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the PPM is

missing.

IMPORTANT: To ensure proper cooling, be sure the processor baffle is installed at all times.

Memory options

This server supports up to four memory boards. Each memory board contains six DIMM slots for a total of 24 DIMM slots in the server. Memory can be expanded by installing PC2-3200R Registered DDR2 DRAM DIMMs.

The server supports a host of AMP options to optimize server availability:

• Advanced ECC (hot-add enabled) ("Advanced ECC Memory" on page 44)

• Advanced ECC (hot-add disabled) ("Advanced ECC Memory" on page 44)

• Online spare memory (on page 45)

• Hot-plug mirrored memory (dual- and quad-board) ("Hot-plug mirrored memory" on page 46)

• Hot-plug RAID memory (on page 47)

Hot-plug operations can be hot-add or hot-replace. Hot-add makes additional memory resources available to the OS. Hot-replace allows failed or degraded DIMMs to be replaced while the server is running.

The maximum supported memory per memory board is 16 GB using four 4-GB dual-rank DIMMs. Although six DIMM slots exist per board, the system architecture allows a maximum of only four dual-rank DIMMs per memory board to optimize performance.

For an overview of single- and dual-rank DIMMs, refer to "Single- and Dual-Rank DIMMs (on page 44)." For DIMM slot locations and bank assignments, refer to "DIMM Slots (on page 20)."

General memory configuration requirements

The following configuration requirements apply regardless of the AMP mode.

• DIMMs must be installed in pairs.

• DIMM pairs in a memory bank must contain DIMMs with the same part number.

• Always populate the memory boards in sequential order: Board 1, Board 2, Board 3, and Board 4.

Any deviation from this requirement results in the server booting in Advanced ECC mode and

Advanced ECC guidelines apply.

• Always populate the DIMMs in sequential order per bank: Bank A, Bank B, and Bank C.

• Dual-rank DIMMs ("Single- and Dual-rank DIMMs" on page 44) must be populated before single-

rank DIMMs (see table).

• If dual-rank DIMMs are installed in Bank A and Bank B, no additional DIMMs may be installed in

Bank C.

• The following table lists all seven valid combinations of single- and dual-rank DIMM configurations

for a memory board. "Single" indicates a bank of single-rank DIMMs. "Dual" indicates a bank of

dual-rank DIMMs.

NOTE: A bank contains two DIMMs.

Configuration Bank A Bank B Bank C

1 Single 2 Single Single

3 Single Single Single 4 Dual

5 Dual Single 6 Dual Single Single 7 Dual Dual

Hardware options installation 43

•

The system can be configured for any AMP mode in RBSU. RBSU displays a warning message if the

selected AMP mode is not supported by the current configuration. However, if the DIMM

configuration at POST does not meet the requirements for the AMP mode selected in RBSU, the

server defaults to Advanced ECC. The system indicates this by displaying a message during POST

and the status LED for the configured AMP mode flashes amber.

• Unpopulated memory boards (those without any installed DIMMs) can be installed in the server for

storing extra memory boards.

• If the server contains more than 4 GB of memory, consult the OS documentation about accessing the

full amount of installed memory.

Single- and Dual-rank DIMMs

PC2-3200 DIMMs can either be single- or dual-rank. While it is not normally important for you to differentiate between these two types of DIMMs, certain DIMM configuration requirements are based on these classifications.

Certain configuration requirements exist with single- and dual-rank DIMMs that allow the architecture to optimize performance. A dual-rank DIMM is similar to having two separate DIMMs on the same module. Although only a single DIMM module, a dual-rank DIMM acts as if it were two separate DIMMs. The primary reason for the existence of dual-rank DIMMs is to provide the largest capacity DIMM given the current DIMM technology. If the maximum DIMM technology allows for creating 2-GB single-rank DIMMs, a dual-rank DIMM using the same technology would be 4-GB.

Understanding the existence of single- and dual-rank DIMMs is all that is necessary for understanding the memory population guidelines of this server.

Advanced ECC Memory

Advanced ECC Memory is the default memory protection mode for this server. In Advanced ECC, the server is protected against correctable memory errors. The server provides notification if the level of correctable errors exceeds a pre-defined threshold rate. The server does not fail because of correctable memory errors. Advanced ECC provides additional protection over Standard ECC in that it is possible to correct certain memory errors that would otherwise be uncorrectable and result in a server failure. Whereas Standard ECC can correct single-bit memory errors, Advanced ECC can correct single-bit memory errors and multi-bit memory errors if all failed bits are on the same DRAM device on the DIMM.

The following guidelines apply to Advanced ECC Memory:

• All general memory requirements apply ("Memory board LEDs and components" on page 17).

• Advanced ECC mode is supported with 1, 2, 3, or 4 memory boards.

• Hot-add is always enabled for Advanced ECC.

• Board insertions do not convert the AMP mode while the server is running. A server cannot be

converted from Advanced ECC to Online Spare Memory, mirrored memory, or Hot-Plug RAID

memory by inserting a board while the server is running. Board insertions in Advanced ECC are

solely for making additional memory resources available to the OS.

• Advanced ECC is the only mode in which hot-add operations are supported. This is the only mode in

which the amount of memory available to the OS can be increased without a reboot.

• Hot-add is performed by adding a memory board while the server is running, and the additional

memory is made available to the OS without a reboot. The following rules apply to hot-add

operations:

• Boards must be inserted sequentially.

• Multiple hot-add board insertions can be performed on the same server. For example, if a server

has three empty memory board slots, three hot-add board insertions can be performed.

Hardware options installation 44

•

If multiple hot-add operations are performed, allow one board insertion operation to complete (as indicated by the memory board LEDs and OS logs) before inserting another memory board.

• If a memory board (which contains DIMMs) is unlocked while in Advanced ECC mode, audio alarms

and visual alerts occur.

CAUTION: When the memory board locking switch is unlocked in a mode that does not support hot-add or

hot-replace capabilities, audio alarms and visual alerts occur. Removing the memory board at this point causes server failure.

To end the audio alarms and visual alerts, move the memory board locking switch back to the locked position.

This action does not result in data corruption or server failure.

If removal of a single memory board is required and it is the only memory board, power down the server and

make the necessary memory changes.

Online spare memory

Online Spare Memory provides a higher level of memory protection than Advanced ECC. With Online Spare Memory, the probability of a server failing because of uncorrectable memory errors is reduced.

In this mode, memory that is receiving a high rate of correctable memory errors is automatically disengaged and a replacement set of memory is used in its place. Since DIMMs that are receiving a high rate of correctable memory errors have an increased probability of receiving an uncorrectable memory error (which results in a server failure), the server experiences higher availability. The degraded memory can be replaced during scheduled downtime and poses no additional risk to the server.

Online Spare Memory is supported with one to four memory boards installed. On this server, each installed memory board is protected by its own spare memory. No OS support is required.

The following guidelines apply to Online Spare Memory:

• All general memory requirements apply ("Memory board LEDs and components" on page 17).

• Online Spare Memory is supported with 1, 2, 3, or 4 memory boards.

• Each board must have a valid Online Spare configuration. No dependencies exist for the

configuration between different memory boards.

• Each memory board includes its own Online Spare Bank. All boards operate independently in

Online Spare mode. Each board can failover to its Online Spare Bank independent of the other

memory boards. Some boards can be in Online Spare degraded mode while others are still in

operational Online Spare mode.

• The minimum valid Online Spare configuration for a memory board requires at least one bank of

dual-rank DIMMs or two banks of single-rank DIMMs ("Single- and Dual-rank DIMMs" on page 44).

If the server does not meet these requirements, an error message is displayed during POST and the

server defaults to Advanced ECC and Advanced ECC guidelines apply.

• The server automatically configures the optimal Online Spare solution.

• Online Spare Memory does not support any hot-plug operations.

HP recommends the following configurations. These configurations result in optimal use of memory. Other configurations are valid, but do not result in the maximum amount of installed memory being available to the OS.

• If only single-rank DIMMs are used on a memory board, all DIMMs should be of the same size on

that memory board.

• If only dual-rank DIMMs are used on a memory board, all DIMMs should be of the same size on that

memory board.

• If a mixture of single- and dual-rank DIMMs are used on a memory board, the dual-rank DIMMs

should be two times the size of any single-rank DIMM.

Hardware options installation 45

After installing DIMMs, use RBSU to configure the system for online spare memory support.

Hot-plug mirrored memory

Hot-Plug mirrored memory (mirrored memory) provides a higher level of memory protection than either Advanced ECC or Online Spare Memory. With mirrored memory, the server is protected against uncorrectable memory errors that would otherwise result in server failure. Mirrored memory allows the server to keep two copies of all memory data on separate memory boards.

If an uncorrectable error is encountered, the proper data is retrieved from the memory board that does not contain the error. In addition, mirrored memory allows failed or degraded DIMMs to be replaced while the server is running without requiring server downtime. The memory board with the failed DIMM(s) can be removed, failed DIMMs replaced, and the board re-inserted into the server without any interruption to the OS.

Mirrored memory is supported with either two or four memory boards installed. No OS support is required.

Mirrored memory has two configurations: dual-board and quad-board. Single-board mirrored memory is not supported. For either mode, choose "Mirrored" in RBSU.

The following guidelines apply to mirrored memory:

• All general memory requirements apply ("Memory board LEDs and components" on page 17).

• Mirrored memory is supported with two or four memory boards.

• Memory boards 1 and 2 are populated for dual-board mirrored memory. Boards 1, 2, 3, and 4 are

populated for quad-board mirrored memory. Any deviation from these guidelines results in the server

booting in Advanced ECC mode and Advanced ECC guidelines apply.

• Memory boards 1 and 2 form a mirrored pair for dual-board mirrored memory. For quad-board

mirrored memory, memory boards 3 and 4 form an additional mirrored pair.

• Memory boards within a mirrored pair must have the same amount of total memory. However, each

board of the mirrored pair may have different DIMM configurations as long as they have equal total

size. For example, memory boards 1 and 2 could each contain 2 GB of physical memory per board

with board 1 containing two 1-GB DIMMs and board 2 containing four 512-MB DIMMs.

• The amount of memory between mirrored pairs can be different in quad-board mirrored memory

mode. For example, memory pair 1 (boards 1 and 2) can contain 2 GB each while memory pair 2

(boards 3 and 4) contain 4 GB each.

• In quad-board mirrored memory, the two pairs of memory boards operate independently. One of the

pairs of memory boards can be degraded while the other pair of memory boards can still be fully

mirrored.

• Hot-add operations are not permitted. Board removals and insertions in mirrored memory are solely

for the purpose of hot-replace operations.

• For hot-replace to function properly, the memory board must be re-inserted into the location from

which it was removed. If the board is placed into the incorrect slot (for example, if board 2 is

removed in dual-board mirroring mode and re-inserted into memory slots 3 or 4), a configuration

error occurs. Attempting to insert a board into the improper position results in audio alarms and

visual alerts.

• Replace only one board at a time. That is, if memory boards 2 and 4 both contain memory errors,

remove board 2, replace the failed DIMMs, and replace board 2 before proceeding to board 4.

• If a board is inserted into a valid memory slot but with an invalid DIMM configuration (including too

much or too little memory), a DIMM configuration error occurs and a visual alert occurs. Refer to

Memory Board LEDs ("Memory board LEDs and components" on page 17).

• If you remove a board while the server is running and do not replace the board, the next reboot

results in the system defaulting to Advanced ECC and Advanced ECC guidelines apply.

Hot-plug RAID memory

Hot-plug RAID memory (RAID memory) provides a similar level of memory protection as mirrored memory but obtains this protection using less total memory. For example, in a RAID memory configuration, 25% of the installed memory is not available to the OS. In a mirrored memory configuration, however, 50% of the installed memory is not available to the OS. RAID memory protects the server against uncorrectable memory errors that would otherwise result in a server failure.

Although mirrored memory keeps two copies of all memory data, RAID memory keeps only one copy of all memory data and additional parity information. If an uncorrectable memory error is encountered, the server can create the proper data using the parity information and the information from the other memory boards that contain no failures.

As with mirrored memory, RAID memory allows failed or degraded DIMMs to be replaced while the server is running without requiring server downtime. The memory board with the failed DIMM(s) can be removed, failed DIMMs replaced, and the board re-inserted into the server without any interruption to the OS.

RAID memory is only supported if all four memory boards are installed. No OS support is required. The following guidelines apply to Hot-Plug RAID memory:

• All general memory requirements apply ("Memory board LEDs and components" on page 17).

• RAID memory is only supported with four memory boards.

• All four memory boards must have the same amount of total memory. However, each board may

have different DIMM configurations as long as they have equal total size. Any deviation from this

rule results in the server booting in Advanced ECC mode and Advanced ECC guidelines apply.

• No hot-add operations are supported in RAID memory, only hot-replace.

• If you remove a board while the server is running and do not replace it, the next reboot results in the

system reverting to Advanced ECC and Advanced ECC guidelines apply.

Memory boards and DIMMs

NOTE: The ProLiant ML570 G3/G4 memory board operates at different front-side bus speeds:

• In HP ProLiant ML570 Generation 4 Servers, the G3/G4 memory board operates at 667 MHz

or 800 MHz, depending on the front-side bus speed of the installed processor.

• In HP ProLiant ML570 Generation 3 Servers, the G3/G4 memory board operates at 667 MHz

with no performance gain over ProLiant ML570 G3 memory boards.

IMPORTANT: Installing a ProLiant ML570 G3 memory board in an HP ProLiant ML570 G4 Server forces

the front-side bus speed to 667 MHz. If the installed processor has an 800-MHz front-side bus, a message displays at POST.

IMPORTANT: The HP ProLiant ML570 G4 Server does not support hot-add of ProLiant ML570 G3 memory

boards. Inserting the memory board generates an audio alert and the memory board LEDs flash. The memory board does not power up. The board can be removed without powering down the server.

Memory board and DIMM installation, removal, and replacement procedures can be either hot-plug or non-hot-plug, depending on how the server is configured. Hot-plug operations can be hot-add or hotreplace. Hot-add makes additional memory resources available to the OS. Hot-replace allows failed or degraded DIMMs to be replaced while the server is running. Hot-add is only supported with Microsoft® Windows® 2003 or later. Hot-replace has no OS requirements.

The following table illustrates AMP modes that support hot-plug features.

When the server is configured for mirrored or RAID memory, you can perform a hot-replacement procedure in the following manner without powering down the server or experiencing server downtime:

1. Remove a memory board.

2. Replace failed or degraded DIMM(s).

3. Reinstall the memory board in the slot from which it was removed.

The replacement procedures in this section apply to both hot-plug and non-hot-plug memory procedures, except as noted.

IMPORTANT: Be sure to power down the server when performing board removal procedures in a server

that is not configured for Mirrored or Hot-Plug RAID Memory.

Observe the following warnings when performing a hot-plug replacement procedure.

WARNING: Always comply with all electrostatic and thermal guidelines to prevent bodily

injury and ensure a properly functioning system when performing hot-plug operations.

WARNING: To prevent personal injury from hazardous energy:

• Remove watches, rings, or other metal objects.

• Use tools with insulated handles.

• Do not place tools or metal parts on top of batteries.
