Motherboard Status Indicators

The motherboard and modules that are installed on the motherboard contain several
status indicators (LEDs), which are described in the following sections:

■ “DDR3 DIMM Fault Status Indicators” on page 13

■ “Processor Fault Status Indicators” on page 14

■ “Fault Remind Status Indicator” on page 14

■ “STBY PWRGD Status Indicator” on page 14

DDR3 DIMM Fault Status Indicators

Each of the 16 DDR3 DIMM sockets on the motherboard has an amber fault status
indicator (LED) associated with it. If Oracle ILOM determines that a DIMM is faulty,
pressing the Fault Remind button on the motherboard signals the service processor
to light the fault LEDs associated with the faulted DIMMs.

About the Sun Server X4-2 13

Processor Fault Status Indicators

The motherboard includes a fault status indicator (LED) adjacent to each of the two
processor sockets. These LEDs indicate when a processor is faulty. For example, if on
reboot the BIOS detects that there are uncorrectable processor errors recorded in the
machine check architecture (MCA) registers left over from the previous boot, then the
BIOS and Oracle ILOM work together to record and diagnose these errors. If it is
determined that a processor is faulty, pressing the Fault Remind button on the
motherboard signals the service processor to light the fault LED associated with the
faulted processor.

Fault Remind Status Indicator

This status indicator (LED) is located next to the Fault Remind button and is
powered from the super capacitor that powers the fault LEDs on the motherboard.
This LED lights to indicate that the fault remind circuitry is working properly in
cases where no components have failed and, as a result, none of the component fault
LEDs illuminate.

STBY PWRGD Status Indicator

The service instructions for all server internal components require that all AC power
be removed from the power supplies prior to removing the server top cover. This
green status indicator (LED) is labeled STBY PWRGD and is located on the rear of the
server near PCIe slot 2.

Note – If a PCIe card is installed in PCIe slot 2, this LED might not be visible.

The STBY PWRGD LED lights to inform the service technician that the motherboard
is receiving standby power from at least one of the power supplies. This LED is
provided to help prevent service actions on the server internal components while the
AC power cords are installed and power is being supplied to the server.

Diagnostic Tools

There are a variety of diagnostic tools, commands, and indicators you can use to
monitor and troubleshoot the server:

■ LEDs – These indicators provide a quick visual notification of the status of the

server and of some of the CRUs and FRUs.

■ Oracle ILOM firmware – This firmware is located on the service processor and

provides a comprehensive service portal using a command-line interface (CLI) and
browser user interface (BUI) for

■ lights-out management capabilities (such as remote power-on, power-off, etc.)

■ monitoring the health of the environmental subsystem (such as power, fans,

temperature, cover interlock, etc.),

■ and fault management and automated diagnosis capabilities during server

initialization (such as QuickPath Interconnect code and Memory Reference
code) and server runtime

22 Sun Server X4-2 Service Manual • May 2014

■ Pc-Check – Accessed through Oracle ILOM, the DOS-based Pc-Check utility tests

motherboard components such as processor, memory, and I/O, as well as ports
and slots. If enabled through Oracle ILOM, this utility will run each time the
system powers on. For information about Pc-Check, refer to the Oracle X86 Servers
Diagnostics, Applications, and Utilities Guide for Servers With Oracle ILOM 3.1 at

http://www.oracle.com/goto/x86AdminDiag/docs.

■ SNMP– Simple Network Management Protocol (SNMP) traps are generated by

the SNMP agents that are installed on the SNMP devices being managed by
Oracle ILOM. Oracle ILOM receives the SNMP traps and converts them into
SNMP event messages that appear in the event log.

■ POST – Power-on self-test (POST) performs diagnostics on system components

upon system power-on and resets to ensure the integrity of those components.
POST messages are displayed and logged in the BIOS event logs. POST works
with Oracle ILOM to take faulty components offline, if needed.

■ Oracle Solaris OS Diagnostic Tools

■ Oracle Solaris OS Predictive Self-Healing (PSH) – The PSH technology

provides automated diagnosis of error events encountered with the processor,
memory subsystem, and integrated I/O subsystem during runtime. The ability
of PSH to off-line faulty processors and retire memory pages during runtime
enhances system availability and prevents future interruptions. The Oracle
Solaris OS PSH technology in conjunction with ILOM and BIOS provide
extensive fault management architecture for placing processors offline and
disabling DIMMs.

■ Log files and console messages – These items provide the standard Oracle

Solaris OS log files and investigative commands that can be accessed and
displayed on the device of your choice.

■ Oracle VTS software – This application exercises the system, provides

hardware validation, and discloses possible faulty components with
recommendations for repair.

The LEDs, Oracle ILOM, Oracle Solaris OS PSH, and many of the log files and
console messages are integrated. For example, Oracle Solaris software will display a
detected fault, log it, pass information to Oracle ILOM where it will be logged, and,
depending on the fault, might cause one or more LEDs to light.

FRU TLI Auto-Update

Oracle ILOM includes a top-level indicator (TLI) auto-update feature that ensures
that the TLI stored in the server field-replaceable units (FRUs) is always correct. The
TLI, which is unique to each server, is used to track the server service entitlement
and warranty coverage. When a server requires service, the server TLI is used to
verify that the warranty on the server has not expired.

The TLI is stored in the FRUID (field-replaceable unit identifiers) of these
components: power supply 0 (PSU 0), motherboard (MB), and disk backplane (DBP).

The TLI components stored in each component FRUID include:

■ Product name

■ PPN (product part number)

■ PSN (product serial number)

When a server FRU that contains the TLI is removed and a replacement module
installed, the TLI of the replacement module is programmed by Oracle ILOM to
contain the same TLI as the other two modules.

Safety Symbols

The following symbols might appear in this book. Note their meanings.

Caution – There is a risk of personal injury or equipment damage. To avoid

personal injury or equipment damage, follow the instructions.

Electrostatic Discharge Safety

Devices that are sensitive to electrostatic discharge (ESD), such as the motherboard,
PCIe cards, drives, processors, and memory cards require special handling.

Caution – The boards and drives contain electronic components that are extremely

sensitive to static electricity. Ordinary amounts of static electricity from clothing or
the work environment can destroy components. Do not touch the components along
their connector edges.

Do the following when handling ESD-sensitive components:

■ Use an antistatic wrist strap.

Wear an antistatic wrist strap and use an antistatic mat when handling
components such as drive assemblies, boards, or cards. When servicing or
removing server components, attach an antistatic strap to your wrist and then to a
metal area on the chassis. Then disconnect the power cords from the server.
Following this practice equalizes the electrical potentials between you and the
server.

Note – An antistatic wrist strap is not included in the Ship Kit for the server.

However, antistatic wrist straps are included with options and components.

■ Use an antistatic mat.

Preparing for Service 31

Storage Drives Hot-Plug Conditions

The solid-state drives (SSDs) or hard-disk drives (HDDs) in the server are
hot-pluggable, but this capability depends on how the drives are configured. To
hot-plug a drive you must be able to take the drive offline before you can remove it.
When you take the drive offline, you prevent any application from accessing the
drive and remove the logical software links to the drive.

The following situations inhibit the ability to perform hot-plugging of a drive:

■ The drive provides the operating system, and the operating system is not mirrored

on another drive.

■ The drive cannot be logically isolated from the online operations of the server.

If either of the above drive restrictions is true, then you must shut down the system
before you replace the drive. See “Powering Down the Server” on page 33.

Note – Replacing a drive does not require removing the server from a rack.

Related Information

■ “Remove a Storage Drive” on page 47

■ “Install a Storage Drive” on page 49

HDD or SSD Failure and RAID

A single storage drive failure does not cause a data failure if the storage drives are
configured as a mirrored RAID 1 volume (optional). The storage drive can be
removed, and when a new storage drive is inserted, the contents are automatically

46 Sun Server X4-2 Service Manual • May 2014

rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If
the replaced storage drive was configured as a hot-spare, the new storage drive is
automatically configured as a new hot-spare.

For instructions for configuring RAID on the server, refer to the Sun Server X4-2

Installation Guide, “Configuring Server Drives for OS Installation” on page 113.

Storage Drive Status Indicators

Servicing Power Supplies (CRU)

The redundant power supplies on the server support concurrent maintenance, which
enables you to remove and replace a power supply without shutting down the
server, provided that the other power supply is online and working.

The server supports model A256 (600 watt) power supplies. The A256 power supply
unit (PSU) provides conversion from the AC lines to the system, accepting ranges
from 100-240 volts AC (VAC). These PSUs are designed to be hot-swappable, and in
most cases will provide fully redundant ”1+1” power, allowing the system to suffer
the loss of a PSU or an AC feed with no loss to system availability.

In maximally configured systems, it is possible that the worst-case power
consumption of the system could exceed the capacity of a single PSU. The PSUs
provide an over-subscription mode, which allows the system to operate with
fault-tolerance even with modest excursions beyond the rated capacity of a single
PSU. This over-subscription support is accomplished using hardware signaling
between the PSU and motherboard circuitry, which can force the system to throttle
maximally CPU and memory power in the event that a PSU is lost. The resulting
power savings will be enough to allow the system to continue to run (in a
lower-performance state) until the power problem is resolved.

The following indicators are lit when a power supply fault is detected:

■ Front and rear Service Required LEDs

■ Amber Service Required LED on the faulty power supply

■ Rear Power Supply Fault LED located on the server front panel (see “Front Panel

Controls and Indicators on a System With Eight 2.5-inch Drives” on page 3)

If a power supply fails and you do not have a replacement available, leave the failed
power supply installed to ensure proper airflow in the server.

In addition to the service procedures included here, you can see animations that
show how to remove and install the power supplies.

Note – After you have replaced Power Supply 0, you must reset the Oracle ILOM

service processor (SP) to propagate the FRU top-level indicator (TLI) data to the new
power supply. For instructions on resetting the SP, see the Oracle Integrated Lights
Out Manager (ILOM) 3.1 Configuration and Maintenance Guide at

http://www.oracle.com/goto/ILOM/docs. Power Supply 1 does not contain

FRU TLI data, and therefore does not require an SP reset after replacement.

The Sun Server X4-2 supports a variety of DDR3 DIMM configurations that can
include quad-rank (QR), dual-rank (DR), and single-rank (SR) DDR3 DIMMs.

Note – While single-rank DIMMs can be installed in the Sun Server X4-2, Oracle

does not offer any single-rank DIMMs for purchase, either as factory-installed
options or as separately orderable options.

Caution – These procedures require that you handle components that are sensitive

to electrostatic discharge. This sensitivity can cause the components to fail. To avoid
damage, ensure that you follow antistatic practices as described in “Take Antistatic

Measures” on page 42.

Caution – Ensure that all power is removed from the server before removing or

installing DDR3 DIMMs, or damage to the DDR3 DIMMs might occur. You must
disconnect all power cables from the system before performing these procedures.

Performance

This section provides an example of how to populate the DIMM sockets to achieve
optimal system performance.

Note – Not all possible configurations are shown here.

The following figure shows the order in which the DIMM sockets should be
populated in dual-processor systems. In single-processor systems, you should follow
the same order except that you should not install DIMMs in the DIMM sockets
associated with processor 1 (P1) socket, because the P1 DIMM sockets are
nonfunctional.

FIGURE: DIMM Population Order

For more information on populating the DIMMs, see the following sections:

Servicing CRUs That Require Server Power-Off 65

■ “DIMM Population Order for Single-Processor Systems” on page 66

■ “DIMM Population Order for Dual-Processor Systems” on page 66

DIMM Population Order for Single-Processor Systems

In single-processor systems, DIMMs should only be installed into DIMM sockets
associated with processor 0 (P0) starting with P0 D0, first filling the blue sockets and
then the white. This DIMM population order is illustrated in FIGURE: DIMM

Population Order on page 65.

The following table describes the order in which the DIMM sockets should be

DIMM Population Rules

The DIMM population rules for the server are as follows:

■ In dual-processor systems, all DIMM sockets can have either a DIMM or DIMM

filler panel installed.

Note – In dual-processor systems, DIMM filler panels are not required in sockets

that do not have DIMMs installed.

■ In single-processor systems, all DIMM sockets associated with processor 0 (P0)

socket can have either a DIMM or DIMM filler panel installed. DIMM sockets
associated with processor 1 (P1) socket must remain empty, that is, neither DIMMs
nor DIMM filler panel should be installed.

Note – In single-processor systems, DIMM filler panels are not required in sockets

that do not have DIMMs installed.

■ A single DIMM configuration is supported.

■ Do not populate DIMM sockets next to an empty processor socket. Each processor

contains a separate memory controller.

Servicing CRUs That Require Server Power-Off 67

■ Each processor has four channels and can support two DIMMs per channel for a

maximum of eight quad-rank (QR) Load Reduced DIMMs (LRDIMMs), dual-rank
(DR) DIMMs, or single-rank (SR) DIMMs.

■ The server supports 32-GB QR LRDIMMs in addition to 8-GB and 16-GB

Registered DIMMs (RDIMMs).

■ You cannot mix LRDIMMs and RDIMMs in the same server. If you choose to

install 32-GB QR LRDIMMs in the server, you cannot install any 8-GB or 16-GB
single-rank or dual-rank RDIMMs.

■ If a you are installing a mix of RDIMM sizes (for example, 8-GB and 16-GB), install

the larger RDIMMs first, then the smaller RDIMMs, until all of the RDIMMs are
installed.

■ If you are installing QR LRDIMMs within a channel, populate the blue sockets

prior to populating the white sockets.

Note – While the processor used in the server supports four modes of

operation—Independent Channel Mode, Lockstep Channel Mode, Mirrored Channel
Mode, and, Device Tagging Mode—the server supports the Independent Channel
Mode only.

Note – Each processor (P0, P1) has eight associated DIMM sockets, numbered D0,

D1, D2, D3, D4, D5, D6, and D7.

■ DIMMs should be installed into DIMM sockets starting with P0 D0 and

alternating between sockets associate with P0 and matching sockets for P1, first
filling the blue sockets and then the white. For an example of a configuration that
follows this rule, see “DIMM Population Example for Optimal System

Performance” on page 65.

■ For maximum performance, apply the following rules:

■ The best performance is ensured by preserving symmetry. For example, add

four of the same kind of DIMMs, one per memory channel, and if the server has
two processors, ensure that both processors have the same size of DIMMs
installed in the same manner.

■ For optimal performance, the memory installation should be identical across

both sockets. Populate each socket with QR, DR, or SR DIMMs in sets of four,
one per memory channel.

■ All memory installed in the system will operate at the same speed. DIMM

operational speed, or frequency, is limited to the lowest speed determined by each
of the following factors:

■ Maximum memory frequency supported by processor

■ Maximum memory frequency supported by the installed DIMMs

■ Memory configuration within a channel

68 Sun Server X4-2 Service Manual • May 2014

The table below lists the memory speed limitations associated with all the possible
combinations of DIMMs within an individual memory channel.

a label identifying its rank classification. The following table identifies the label
corresponding to each DIMM rank classification:

Inconsistencies Between DIMM Fault Indicators
and the BIOS Isolation of Faulty DIMMs

When a single DIMM is marked as faulty by Oracle ILOM (for example,
fault.memory.intel.dimm.training-failed is listed in the SP Event Log),
BIOS might disable the entire memory channel that contains the faulty DIMM as
failing, that is, up to two DIMMs. As a result, the memory available to the operating
system is reduced. However, when the Fault Remind button is pressed, only the fault
status indicator (LED) associated with the faulty DIMM lights. The fault LED for the
other DIMM in the memory channel remains off. Therefore, you can correctly
identify the faulty DIMM.

When the faulty DIMM is replaced, the memory available to the operating system
returns to normal. If the DIMM fault message in Oracle ILOM is not cleared under
Open Problems, you must manually clear the fault in Oracle ILOM. For instructions
for manually clearing a DIMM fault, see the procedure "Clear Faults for Undetected
Replaced or Repaired Hardware Components" in the Oracle Integrated Lights Out
Manager (ILOM) 3.1 User’s Guide in the Oracle Integrated Lights Out Manager (ILOM)

3.1 Documentation Library at http://www.oracle.com/goto/ILOM/docs.

Using the Fault Remind Button

When the Fault Remind button is pressed, an LED located next to the Fault Remind
button lights green to indicate that there is sufficient voltage present in the fault
remind circuit to light any fault LEDs that were lit due to a failure. If this LED fails to
light when you press the Fault Remind button, it is likely that the capacitor powering
the fault remind circuit has lost its charge. This can happen if the Fault Remind
button is pressed for a long time with fault LEDs lit or if power has been removed
from the server for more than 15 minutes.

The following figure shows the location of the Fault Remind button.

2. Identify and note the location of the faulty DDR3 DIMM by pressing the Fault

Remind button on the motherboard (see “Using the Fault Remind Button” on

page 70).

Faulty DDR3 DIMMs are identified with a corresponding amber LED on the
motherboard.

■ If the DIMM fault LED is off, the DIMM is operating properly.

■ If the DIMM fault LED is on (amber), then the DIMM is faulty and should be

replaced.

3. To remove the faulty DIMM do the following:

a. Rotate both DIMM socket ejectors outward as far as they will go.

The DIMM is partially ejected from the socket (See FIGURE: DIMM Socket

Release and Alignment on page 73).

b. Carefully lift the DIMM straight up to remove it from the socket.

4. Replace each faulty DIMM with either another DIMM of the same rank size
(quad rank, dual rank, or single rank) or leave the socket empty.

Note – DIMM filler panels are optional and not required.

For DIMM replacement instructions, see “Install a DIMM” on page 73.

Servicing PCIe Cards (CRU)

These sections describe how to remove and install PCIe cards. Refer to your PCIe
card documentation for complete software and cabling information about your card.

In addition to the service procedures included here, you can see animations that
show how to remove and install the PCIe cards.

To play the Sun Server X4-2 Service Animations go to:

http://docs.oracle.com/cd/E36975_01/html/E49470/index.html

Caution – These procedures require that you handle components that are sensitive

to electrostatic discharge. This sensitivity can cause the components to fail. To avoid
damage, ensure that you follow antistatic practices as described in “Take Antistatic

Measures” on page 42.

Caution – Ensure that all power is removed from the server before removing or

installing PCIe cards. You must disconnect all power cables from the system before
performing these procedures.

Note – For a complete list of supported PCIe cards, see the Sun Server X4-2 Product

Notes at http://www.oracle.com/goto/X4-2/docs.

PCIe Slot Characteristics

There are three external and one internal PCIe slots available in the Sun Server X4-2.
The external slots support optional, standard PCIe cards and are numbered 1, 2, and
3 from left to right when you view the server from the rear. The internal slot, which
installs on the riser in PCIe slots 3 and 4, supports a required internal SAS controller
HBA card. For a view of the rear panel that shows PCIe slot numbering, see “Server

Back Panel View” on page 5.

Note – PCIe slot 1 is nonfunctional in single-processor systems.

Note – All of the PCIe slots comply with the PCI Express 3.0 specification and can

accommodate 25 watt PCIe cards.

The following table lists the characteristics and requirements of the PCIe slots.

▼ Remove a PCIe Card From PCIe Slot 1 or 2

Note – PCIe slot 1 is nonfunctional in single-processor systems.

1. Remove the PCIe riser from the server.

For instructions, see “Remove a PCIe Riser From PCIe Slot 1 or 2” on page 76.

2. Remove the PCIe card from the PCIe riser.

a. Hold the riser in one hand and use your other hand to carefully pull the PCIe

card connector out of the riser.

b. Disconnect the rear bracket that is attached to the PCIe card from the rear of

the PCIe riser.

3. Place the PCIe card on an antistatic mat.

Caution – Whenever you remove a PCIe card, you should replace it with another

PCIe card or a PCIe filler panel. Installing PCIe filler panels in vacant PCIe slots
helps reduce the level of electromagnetic interference (EMI) emitted by the server.
For instructions for installing a PCIe filler panel, see “Removing and Installing Server

Filler Panels” on page 143.
