System maintenance switch procedures
When you perform troubleshooting steps, this guide may instruct you to perform the following procedures:
• Clear the system configuration ("Clearing the system configuration" on page 8).
• Access the redundant ROM ("Accessing the redundant ROM" on page 9).
To complete these procedures, you must change physical settings on the system maintenance switch.
Clearing the system configuration
RBSU can be used to restore the factory default configuration. For more information, see "HP ROM-Based
Setup Utility (on page 49)." If the system is unable to boot into RBSU, use the following steps to clear the
system configuration:
1. Power down the server blade (on page 11).
2. Remove the server blade (on page 12).
3. Remove the access panel (on page 13).
4. Change position 6 of the system maintenance switch to on.
Component identification 8
5. Install the access panel (on page 13).
6. Install the server blade in the enclosure and power up the server blade.
7. Wait for the POST message that prompts you to change the switch setting:
Maintenance switch detected in the "On" position.
Power off the server and turn switch to the "Off" position.
8. Repeat steps 1 through 3.
9. Change position 6 of the system maintenance switch to off.
10. Repeat steps 5 and 6.
IMPORTANT: When the server blade boots after NVRAM is cleared, a delay of up to 2 minutes
is normal. During this delay, the system appears non-functional. Do not attempt any procedures
during the delay.
Accessing the redundant ROM
If the system ROM is corrupted, the system automatically switches to the redundant ROM in most cases. If the
system does not automatically switch to the redundant ROM, perform the following steps:
1. Power down the server blade (on page 11).
2. Remove the server blade (on page 12).
3. Remove the access panel (on page 13).
4. Change positions 1, 5, and 6 of the system maintenance switch to on.
5. Install the access panel (on page 13).
6. Install the server blade in the enclosure and power up the server blade.
7. After the system beeps, repeat steps 1 through 3.
8. Change positions 1, 5, and 6 of system maintenance switch to off.
9. Repeat steps 5 and 6.
If both the current and backup versions of the ROM are corrupt, return the system board for a service
replacement.
To switch to the backup ROM when the System ROM is not corrupt, use RBSU.

Operations
Power up the server blade
The HP BladeSystem Onboard Administrator initiates an automatic power-up sequence when the server
blade is installed. If the default setting is changed, use one of the following methods to power up the server
blade:
• Use a virtual power button selection through iLO 3.
• Press and release the Power On/Standby button.
When the server blade goes from the standby mode to the full power mode, the system power LED changes
from amber to green.
For more information about the HP BladeSystem Onboard Administrator, see the enclosure setup and
installation guide on the HP website (http://www.hp.com/support).
For more information about iLO 3, see "iLO 3 technology (on page 54)."
Power down the server blade
Before powering down the server blade for any upgrade or maintenance procedures, perform a backup of
critical server data and programs.
Depending on the HP BladeSystem Onboard Administrator configuration, use one of the following methods
to power down the server blade:
• Use a virtual power button selection through iLO 3.
This method initiates a controlled remote shutdown of applications and the OS before the server blade
enters standby mode.
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server blade enters
standby mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server blade to enter
standby mode.
This method forces the server blade to enter standby mode without properly exiting applications and the
OS. It provides an emergency shutdown method if an application stops responding.
• Execute one of the following commands using the HP BladeSystem Onboard Administrator CLI:
poweroff server [bay number]
or
poweroff server [bay number] force
The first command initiates a controlled shutdown of applications and the OS before the server blade
enters standby mode. The second form of the command forces the server blade to enter standby mode
without exiting applications and the OS. This emergency method forces a shutdown if an application
stops responding.
Operations 11
• Use the HP BladeSystem Onboard Administrator GUI to initiate a shutdown:
a. Select the Enclosure Information tab, and then select the Overall checkbox in the Device Bays item.
b. Initiate a shutdown from the Virtual Power menu:
— Select Momentary Press to initiate a controlled shutdown of applications and the OS.
— Select Press and Hold to initiate an emergency shutdown of applications and the OS.
IMPORTANT: When the server blade is in standby mode, auxiliary power is still being provided.
To remove all power from the server blade, remove the server blade from the enclosure.
After initiating a virtual power down command, be sure that the server blade is in standby mode by
observing that the system power LED is amber.

Memory options
IMPORTANT: This server blade 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 blade 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 blade must be the same type.
The server blade supports the following DIMM speeds:
Hardware options installation 21
• 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 "General DIMM slot population guidelines (on page 25)."
Memory subsystem architecture
The memory subsystem in this server blade is divided into channels. Each processor supports three channels,
and each channel supports three DIMM slots, as shown in the following table.

This multi-channel architecture provides enhanced performance in Advanced ECC mode. This architecture
also enables the Mirrored Memory and Lockstep memory modes. This server blade supports both Registered
PC3 DIMMs (RDIMMs) and Unbuffered DIMMs (UDIMMs).
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 blade 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 4-GB,
and a quad-rank DIMM would be 8-GB.
DIMM identification
IMPORTANT: This server blade does not support mixing RDIMMs and UDIMMs. Attempting to
mix these two types causes the server to halt during BIOS initialization.
Hardware options installation 22
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.

Memory configurations
To optimize server blade availability, the server blade supports the following AMP modes:
• Advanced ECC—provides the greatest memory capacity for a given DIMM size, while providing up to
4-bit error correction. This mode is the default option for this server blade.
• Mirrored Memory—provides maximum protection against failed DIMMs. Uncorrectable errors in one
channel are corrected by the mirror channel.
• Lockstep—provides enhanced protection while making all installed memory available to the operating
system. The server blade can continue to function if a single- or multi-bit memory failure within a single
DRAM device occurs.
Advanced Memory Protection options are configured in RBSU. If the requested AMP mode is not supported
by the installed DIMM configuration, the server blade boots in Advanced ECC mode. For more information,
see "HP ROM-Based Setup Utility (on page 49)."
Hardware options installation 23
For the latest memory configuration information, see the QuickSpecs on the HP website
(http://www.hp.com).
RDIMM maximum memory configurations
The following table lists the maximum memory configuration possible with 8-GB RDIMMs.
Rank Single-processor Dual-processor
Single-rank
Dual-rank
Quad-rank
72 GB 144 GB
72 GB 144 GB
48 GB 96 GB
UDIMM maximum memory configurations
The server blade supports a maximum of 12 GB with one processor and 24 GB with two processors using
2-GB single- or dual-rank UDIMMs.
Advanced ECC memory configuration
Advanced ECC memory is the default memory protection mode for this server blade. Standard ECC can
correct single-bit memory errors and detect multi-bit memory errors. When multi-bit errors are detected using
Standard ECC, the error is signaled to the server blade and causes the server blade to halt.
Advanced ECC protects the server blade against some multi-bit memory errors. Advanced ECC can correct
both single-bit memory errors and 4-bit memory errors if all failed bits are on the same DRAM device on the
DIMM.
Advanced ECC provides additional protection over Standard ECC because it is possible to correct certain
memory errors that would otherwise be uncorrected and result in a server blade failure. The server blade
provides notification that correctable error events have exceeded a pre-defined threshold rate.
Mirrored memory configuration
Mirroring provides protection against uncorrected memory errors that would otherwise result in server blade
downtime. Mirroring is performed at the channel level. Channels 1 and 2 are used; channel 3 is not
populated.
Data is written to both memory channels. Data is read from one of the two memory channels. If an
uncorrectable error is detected in the active memory channel, data is retrieved from the mirror channel. This
channel becomes the new active channel, and the system disables the channel with the failed DIMM.
Lockstep memory configuration
Lockstep mode provides protection against multi-bit memory errors that occur on the same DRAM device.
Lockstep mode can correct any single DRAM device failure on x4 and x8 DIMM types. The DIMMs in each
channel must have identical HP part numbers.
Lockstep mode uses channel 1 and channel 2. Channel 3 is not populated. Because channel 3 cannot be
populated when using Lockstep mode, the maximum memory capacity is lower than Advanced ECC mode.
Memory performance with Advanced ECC is also slightly higher.
Hardware options installation 24
General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
• Populate DIMM slots for a processor only if the processor is installed.
• To maximize performance in multi-processor configurations, distribute the total memory capacity
between all processors as evenly as possible.
• Do not mix Unbuffered and Registered PC3 DIMMs.
• Each channel supports up to two Unbuffered DIMMs.
• If quad-rank DIMMs are installed for a 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.
DIMM speeds are supported as indicated in the following table.

Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
• Observe the general DIMM slot population guidelines (on page 25).
• DIMMs may be installed individually.
Single-processor Advanced ECC population order
For Advanced ECC mode configurations with a single processor, populate the DIMM slots in the following
order:
• RDIMM: Sequentially in alphabetical order (A through I)
• UDIMM: A through F, sequentially in alphabetical order. Do not populate DIMM slots G through I.
Multi-processor Advanced ECC population order
For Advanced ECC mode configurations with multiple processors, populate the DIMM slots for each
processor in the following order:
• RDIMM: Sequentially in alphabetical order (A through I)
• UDIMM: A through F, sequentially in alphabetical order. Do not populate DIMM slots G through I.
Mirrored Memory population guidelines
For Mirrored Memory mode configurations, observe the following guidelines:
• Observe the general DIMM slot population guidelines (on page 25).

• Always install DIMMs in channels 1 and 2 for each installed processor.
• Do not install DIMMs in channel 3 for any processor.
• DIMMs installed on channel 1 and channel 2 of an installed processor must be identical.
• In multi-processor configurations, each processor must have a valid Mirrored Memory configuration.
• In multi-processor configurations, each processor may have a different valid Mirrored Memory
configuration.
Single-processor Mirrored Memory population order
For Mirrored Memory mode configurations with a single processor, populate the DIMM slots in the following
order:
• RDIMM
o First: A and B
o Next: D and E
o Last: G and H
o Do not populate slots C, F, or I.
• UDIMM
o First: A and B
o Last: D and E
o Do not populate slots C, F, G, H, or I.
After installing the DIMMs, use RBSU to configure the system for Mirrored Memory support ("Configuring
mirrored memory" on page 51).
