What your server offers

The server uses the following features and technologies:

v UEFI-compliant server firmware

IBM System x Server Firmware offers several features, including Unified
Extensible Firmware Interface (UEFI) 2.1 compliance, Active Energy Manager
technology, enhanced RAS capabilities, and BIOS compatibility support. UEFI
replaces the basic input/output system (BIOS) and defines a standard interface
between the operating system, platform firmware, and external devices.
UEFI-compliant System x servers are capable of booting UEFI-compliant
operating systems, BIOS-based operating systems, and BIOS-based adapters as
well as UEFI-compliant adapters.

Note: The server does not support DOS.

v Integrated management module

The integrated management module (IMM) combines service processor
functions, video controller, and (when an optional virtual media key is installed)
remote presence function in a single chip. The IMM provides advanced
service-processor control, monitoring, and alerting function. If an environmental
condition exceeds a threshold or if a system component fails, the IMM lights
LEDs to help you diagnose the problem, records the error in the event log, and
alerts you to the problem. Optionally, the IMM also provides a virtual presence
capability for remote server management capabilities. The IMM provides remote
server management through industry-standard interfaces:

– Intelligent Platform Management Interface (IPMI) version 2.0

8 System x3650 M3 Types 4255, 7945, and 7949: Installation and User’s Guide

– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
– Web browser

v Remote presence capability and blue-screen capture

The optional virtual media key is required to enable the remote presence and
blue-screen capture features. The remote presence feature provides the following
functions:

– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz,

regardless of the system state

– Remotely accessing the server, using the keyboard and mouse from a remote

client

– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a

remote client, and mapping ISO and diskette image files as virtual drives that
are available for use by the server

– Uploading a diskette image to the IMM memory and mapping it to the server

as a virtual drive

The blue-screen capture feature captures the video display contents before the
IMM restarts the server when the IMM detects an operating-system hang
condition. A system administrator can use the blue-screen capture to assist in
determining the cause of the hang condition.

v IBM Dynamic System Analysis Preboot diagnostics programs

The Dynamic System Analysis (DSA) Preboot diagnostics programs are stored
on the integrated USB memory. It collects and analyzes system information to aid
in diagnosing server problems. The diagnostic programs collect the following
information about the server:

– System configuration
– Network interfaces and settings
– Installed hardware
– Light path diagnostics status
– Service processor status and configuration
– Vital product data, firmware, and UEFI (formerly BIOS) configuration
– Hard disk drive health
– RAID controller configuration
– Event logs for ServeRAID controllers and service processors
The diagnostic programs create a merged log that includes events from all

collected logs. The information is collected into a file that you can send to IBM
service and support. Additionally, you can view the information locally through a
generated text report file. You can also copy the log to a removable media and
view the log from a Web browser.

For additional information about DSA Preboot diagnostics, see the Problem
Determination and Service Guide on the IBM Documentation CD

v IBM Systems Director

IBM Systems Director is a workgroup-hardware-management tool that you can
use to centrally manage System x and xSeries servers. For more information,
see the IBM Systems Director documentation on the IBM Systems Director CD.

v Active Energy Manager

The Active Energy Manager solution is an IBM Systems Director extension that
measures and reports server power consumption as it occurs. This enables you
to monitor power consumption in correlation to specific software application

Chapter 1. The System x3650 M3 server 9

programs and hardware configurations. You can obtain the measurement values
through the systems-management interface and view them, using IBM Systems
Director. For more information, see the IBM Director documentation on the IBM
Systems Director CD, or see http://www.ibm.com/systems/management/director/
extensions/actengmrg.html.

v IBM X-Architecture technology

IBM X-Architecture technology combines proven, innovative IBM designs to make
your Intel-processor-based server powerful, scalable, and reliable. For more
information, see http://www.ibm.com/servers/eserver/xseries/xarchitecture/
enterprise/index.html.

™

– Active

Memory

The Active Memory™feature improves the reliability of memory through
memory mirroring. Memory mirroring stores data in two pairs of DIMMs
simultaneously.

– Large system-memory capacity

The memory bus supports up to 192 GB of system memory when registered
DIMMs are installed. The server supports up to 48 GB if unbuffered DIMMs
are installed. The memory controller supports error correcting code (ECC) for
up to 18 industry-standard PC3-10600R-999, 800, 1067, and 1333 MHz,
DDR3 (third-generation double-data-rate), synchronous dynamic random
access memory (SDRAM) dual inline memory modules (DIMMs).

v IBM ServerGuide Setup and Installation CD

The ServerGuide Setup and Installation CD, which you can download from the
Web, provides programs to help you set up the server and install a Windows
operating system. The ServerGuide program detects installed optional hardware
devices and provides the correct configuration programs and device drivers. For
more information about the ServerGuide Setup and Installation CD, see “Using
the ServerGuide Setup and Installation CD” on page 150.

v Integrated network support

The server comes with two integrated Broadcom Gigabit Ethernet controllers,
which support connection to a 10 Mbps, 100 Mbps, or 1000 Mbps network. For
more information, see “Configuring the Gigabit Ethernet controller” on page 156.

v Large data-storage and hot-swap capability

The server supports up to eight or sixteen 2.5-inch hot-swap hard disk drives in
the hot-swap bays (depending on the model and optional devices installed). With
the hot-swap feature, you can add, remove, or replace hard disk drives without
turning off the server.

v Light path diagnostics

Light path diagnostics provides LEDs to help you diagnose problems. For more
information, see the section about light path diagnostics in the Problem
Determination and Service Guide.

v PCI adapter capabilities

The server supports up to four PCI interface slots. For more information, see
“Installing a PCI adapter” on page 52.

v Memory mirroring

Memory mirroring improves the availability of memory by writing information to
the main memory and redundant locations in a mirrored pair of DIMMs.

v Redundant connection

The addition of the optional Ethernet daughter card provides failover capability to
a redundant Ethernet connection with the applicable application installed. If a
problem occurs with the primary Ethernet connection and the optional Ethernet

10 System x3650 M3 Types 4255, 7945, and 7949: Installation and User’s Guide

daughter card is installed on the server, all Ethernet traffic that is associated with
the primary connection is automatically switched to the optional redundant
Ethernet daughter card connection. If the applicable device drivers are installed,
this switching occurs without data loss and without user intervention.

v Redundant cooling and optional power capabilities

The server supports three hot-swap fans, which provide redundant cooling.
Redundant cooling enables continued operation if one of the fans fails. The
server supports a maximum of two 675-watt or 460-watt hot-swap power
supplies, which provide redundancy and hot-swap capability for a typical
configuration. The server comes with one 675-watt or 460-watt hot-swap power
supply. You can order the second optional power supply for power redundancy. If
the maximum load on the server is less than 675-watts (or 460-watt, depending
on what kind of power supply you use) and a problem occurs with one of the
power supplies, the other power supply can meet the power requirements.

Note: If the maximum load on the server is greater than 675-watts (or 460-watt,
depending on what kind of power supply you use) and a problem occurs with one
of the power supplies, Active Energy Manager can act to minimize the load
somewhat so that the server can function with the remaining power supply.

v ServeRAID support

The server supports an internal ServeRAID SAS controller, which is required for
you to use the hot-swap hard disk drives and to create redundant array of
independent disks (RAID) configurations.

v Systems-management capabilities

The server contains an integrated management module (IMM) which enables you
to manage the functions of the server locally and remotely. The addition of the
optional IBM Virtual Media Key provides remote presence and blue-screen
capture capability. The IMM also provides system monitoring, event recording,
and dial-out alert capability.

v TCP/IP offload engine (TOE) support

The Ethernet controllers in the server support TOE, which is a technology that
offloads the TCP/IP flow from the microprocessors and I/O subsystem to increase
the speed of the TCP/IP flow. When an operating system that supports TOE is
running on the server and TOE is enabled, the server supports TOE operation.
See the operating-system documentation for information about enabling TOE.

Note: As of the date of this document, the Linux operating system does not
support TOE.

Reliability, availability, and serviceability features

Three important computer design features are reliability, availability, and
serviceability (RAS). The RAS features help to ensure the integrity of the data that
is stored in the server, the availability of the server when you need it, and the ease
with which you can diagnose and repair problems.

The server has the following RAS features:
v 3-year parts and 3-year labor limited warranty for machine types 7945 and 7949

and 4-year parts and 4-year labor limited warranty for machine type 4255

IBM Systems Director

IBM Systems Director is a platform-management foundation that streamlines the
way you manage physical and virtual systems in a heterogeneous environment. By
using industry standards, IBM Systems Director supports multiple operating systems
and virtualization technologies in IBM and non-IBM x86 platforms.

Through a single user interface, IBM Systems Director provides consistent views for
viewing managed systems, determining how these systems relate to one another,
and identifying their statuses, helping to correlate technical resources with business
needs. A set of common tasks that are included with IBM Systems Director provides
many of the core capabilities that are required for basic management, which means
instant out-of-the-box business value. These common tasks include discovery,
inventory, configuration, system health, monitoring, updates, event notification, and
automation for managed systems.

The IBM Systems Director Web and command-line interfaces provide a consistent
interface that is focused on driving these common tasks and capabilities:

v Discovering, navigating, and visualizing systems on the network with the detailed

inventory and relationships to the other network resources

12 System x3650 M3 Types 4255, 7945, and 7949: Installation and User’s Guide

v Notifying users of problems that occur on systems and the ability to isolate the

sources of the problems

v Notifying users when systems need updates and distributing and installing

updates on a schedule

v Analyzing real-time data for systems and setting critical thresholds that notify the

administrator of emerging problems

v Configuring settings of a single system and creating a configuration plan that can

apply those setting to multiple systems

v Updating installed plug-ins to add new features and functions to the base

capabilities

v Managing the life cycles of virtual resources

Server power features

When the server is connected to a power source but is not turned on, the operating
system does not run, and all core logic except for the integrated management
module (IMM) is shut down; however, the server can respond to requests from the
IMM, such as a remote request to turn on the server. The power-on LED flashes to
indicate that the server is connected to power but is not turned on.

Chapter 1. The System x3650 M3 server 21

Turning on the server

Approximately 3 minutes after the server is connected to power, the power-control
button becomes active, and one or more fans might start running to provide cooling
while the server is connected to power. You can turn on the server and start the
operating system by pressing the power-control button.

The server can also be turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart

automatically when power is restored.

v If your operating system supports the Wake on LAN feature, the Wake on LAN

feature can turn on the server.

For 32-bit operating systems only: Some memory is reserved for various system
resources and is unavailable to the operating system. The amount of memory that
is reserved for system resources depends on the operating system, the
configuration of the server, and the configured PCI options.

Turning off the server

When you turn off the server and leave it connected to power, the server can
respond to requests from the IMM, such as a remote request to turn on the server.
While the server remains connected to power, one or more fans might continue to
run. To remove all power from the server, you must disconnect it from the power
source.
Important: To view the error LEDs on the system board, leave the server
connected to a power source.

Some operating systems require an orderly shutdown before you turn off the server.
See your operating-system documentation for information about shutting down the
operating system.

Statement 5:

CAUTION:
The power control button on the device and the power switch on the power
supply do not turn off the electrical current supplied to the device. The device
also might have more than one power cord. To remove all electrical current
from the device, ensure that all power cords are disconnected from the power
source.

Chapter 2. Installing optional devices

This chapter provides detailed instructions for installing optional hardware devices in
the server.

In addition to the instructions in this chapter for installing optional hardware devices,
updating firmware and device drivers, and completing the installation, IBM Business
Partners must also complete the steps in “Instructions for IBM Business Partners.”

Important: To help ensure that the devices that you install work correctly and do
not introduce problems, observe the following precautions:

1. Make sure that the server and the installed firmware levels support the devices
that you are installing. If necessary, update the UEFI and IMM firmware and any
other firmware that is stored on the system boards. For information about where
firmware is stored in the server, see Chapter 6, “Configuration information and
instructions,” in the Problem Determination and Service Guide. For a list of
supported optional devices for the server, see http://www.ibm.com/systems/info/
x86servers/serverproven/compat/us/.

2. Before you install optional hardware devices, make sure that the server is
working correctly. Start the server and make sure that the operating system
starts, if an operating system is installed, or that a 19990305 error code is
displayed, indicating that an operating system was not found but the server is
otherwise working correctly. If the server is not working correctly, see the
Problem Determination and Service Guide for information about how to run
diagnostics.

3. Follow the installation procedures in this chapter and use the correct tools.
Incorrectly installed devices can cause system failures because of damaged
pins in sockets or connectors, loose cabling, or loose components.

4. Use the best practices to apply current firmware and device-driver updates for
the server and optional devices. To download the IBM System x Firmware
Update Best Practices document, go to http://www.ibm.com/support/entry/portal/

Installation guidelines

Attention: Static electricity that is released to internal server components when

the server is powered-on might cause the system to halt, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when removing or installing a hot-swap
device.

Before you install optional devices, read the following information:
v Read the safety information that begins on page vii, the guidelines in “Working

inside the server with the power on” on page 38, and “Handling static-sensitive
devices” on page 39. This information will help you work safely.

v When you install your new server, take the opportunity to download and apply

the most recent firmware updates. This step will help to ensure that any known
issues are addressed and that your server is ready to function at maximum levels
of performance. To download firmware updates for your server, complete the
following steps:

1. Go to http://www.ibm.com/systems/support/.

2. Under Product support, click System x.

3. Under Popular links, click Software and device drivers.

4. Click System x3650 M3 to display the matrix of downloadable files for the
server.

For additional information about tools for updating, managing, and deploying
firmware, see the System x and xSeries Tools Center at
http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.

v Before you install optional hardware, make sure that the server is working

correctly. Start the server, and make sure that the operating system starts, if an
operating system is installed, or that a 19990305 error code is displayed,
indicating that an operating system was not found but the server is otherwise
working correctly. If the server is not working correctly, see the Problem
Determination and Service Guide on the IBM System x Documentation CD for
diagnostic information.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v If you must start the server while the cover is removed, make sure that no one is

near the server and that no tools or other objects have been left inside the
server.

v Do not attempt to lift an object that you think is too heavy for you. If you have to

lift a heavy object, observe the following precautions:
– Make sure that you can stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing up

with your leg muscles.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.

Chapter 2. Installing optional devices 37

v To view the error LEDs on the system board and internal components, leave the

server connected to power.

v You do not have to turn off the server to install or replace hot-swap fans,

redundant hot-swap ac power supplies, or hot-plug Universal Serial Bus (USB)
devices. However, you must turn off the server before you perform any steps that
involve removing or installing adapter cables or non-hot-swap optional devices or
components.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.

v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

v For a list of supported optional devices for the server, see http://www.ibm.com/

servers/eserver/serverproven/compat/us/.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that the
following requirements are met:

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the server cover before you turn on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the server cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan within 48 hours.
v You have replaced a hot-swap fan within 30 seconds of removal.
v You have replaced a hot-swap drive within 2 minutes of removal.
v You do not operate the server without the air baffles installed. Operating the

server without the air baffles might cause the microprocessors to overheat.

v Microprocessor 2 air baffle and DIMM air baffle are installed.
v The light path diagnostics panel is not pulled out of the server.

Working inside the server with the power on

Attention: Static electricity that is released to internal server components when

the server is powered-on might cause the server to halt, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when you work inside the server with the
power on.

38 System x3650 M3 Types 4255, 7945, and 7949: Installation and User’s Guide

The server supports hot-plug, hot-add, and hot-swap devices and is designed to
operate safely while it is turned on and the cover is removed. Follow these
guidelines when you work inside a server that is turned on:

v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts

before working inside the server; do not wear cuff links while you are working
inside the server.

v Do not allow your necktie or scarf to hang inside the server.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that might fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the server and other electronic devices.

To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available. Always use an
electrostatic-discharge wrist strap or other grounding system when working inside
the server with the power on.

v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted

metal surface on the outside of the server for at least 2 seconds. This drains
static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server without

setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

indoor humidity and increases static electricity.

a. Connect the shorter SAS signal cable that comes with the option kit to the

SAS controller connector that is labeled “Ports 7-4”. If you are connecting
cables to a ServeRAID-MR10i SAS/SATA Controller, this connector is
closest to the edge of the controller and has two straight connectors.

Note: If you are connecting the shorter SAS signal cable to a
ServeRAID-BR10i v2 SAS/SATA Controller, the connectors are reversed.
You must connect the shorter SAS signal cable to the connector that is
labeled “Port 4–7”, which is the connector that is not the closest to the
edge of the controller.
