Chapter 1. Introducing the IBM xSeries 346 Type 8840 3

What your server offers
The server uses the following features and technologies:
vBaseboard management controller
The baseboard management controller provides environmental monitoring for the
server. If environmental conditions exceed thresholds or if system components
fail, the baseboard management controller lights LEDs to help you diagnose the
problem. Critical errors are also included in the error log.
The baseboard management controller also provides remote server management
capabilities through the OSA SMBridge management utility program.
Note: The baseboard management controller is also known as the service
processor.
vIBM Director
IBM Director is aworkgroup-hardware-management tool that you can use to
centrally manage xSeries servers. For more information about IBM Director, see
the IBM Director documentation on the IBM Director CD.
vIBM Enterprise 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, go to
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 and online-spare memory. Memory mirroring stores data in two pairs
of DIMMs simultaneously. Online-spare memory disables afailed pair of
DIMMs from the system configuration and activates apair of online-spare
memory DIMMs. For more information, see the section about installing DIMMs
in the Installation Guide.
–Large system-memory capacity
The memory bus supports up to 16 GB of system memory. The memory
controller supports error correcting code (ECC) for up to eight
industry-standard, 1.8 V, 240-pin, double-data rate (DDR) II, PC2-3200,
registered, synchronous dynamic random-access memory (SDRAM) dual
inline memory modules (DIMMs).
v
IBM ServerGuide
™ Setup and Installation CD
The ServerGuide Setup and Installation CD that comes with the server provides
programs to help you set up the server and install a32-bit Windows
® operating
system. The ServerGuide program detects installed hardware options 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 18.
vIntegrated network support
The server comes with two integrated Broadcom Gigabit Ethernet controllers,
which support connection to a10-Mbps, 100-Mbps, or 1000-Mbps network. For
more information, see “Configuring the Ethernet controllers” on page 22.
vLarge data-storage and hot-swap capability
The server supports up to six 25.4 mm (1-inch) slim, 3.5-inch hot-swap hard disk
drives installed on Ultra-Slim hard disk drive trays in the hot-swap bays. With the
hot-swap feature, you can add, remove, or replace hard disk drives without
turning off the server.
4IBM xSeries 346 Type 8840: User’s Guide

vLight path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more
information, see the section about light path diagnostics in the Installation Guide.
vRedundant connection
The addition of an optional network interface card (NIC) provides afailover
capability to aredundant Ethernet connection. If aproblem occurs with the
primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. If the applicable
device drivers are installed, this switching occurs without data loss and without
user intervention.
vRedundant cooling and power capabilities
The server supports up to 12 hot-swap fans, which provide redundant cooling.
The server supports up to two 650-watt power supplies, which provide
redundancy and hot-swap capability for atypical configuration.
vServeRAID
™ support
The server supports ServeRAID adapters to create redundant array of
independent disks (RAID) configurations.
vSymmetric multiprocessing (SMP)
Your server supports up to two Intel Xeon microprocessors. If the server comes
with only one microprocessor, you can install an additional microprocessor to
enhance performance and provide SMP capability.
vSystems-management capabilities
The server supports an optional IBM Remote Supervisor Adapter II SlimLine.
This option, when used with the integrated baseboard management controller
that comes with the server, enables you to manage the functions of the server
locally and remotely. The Remote Supervisor Adapter II SlimLine also provides
system monitoring, event recording, and dial-out alert capability.
Reliability, availability, and serviceability
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 correct problems.
The server has the following RAS features:
vAutomatic error retry and recovery
vAutomatic restart after apower failure
vBackup basic input/output system (BIOS) switching under the control of the
service processor
vBaseboard management controller (service processor)
vBuilt-in monitoring for fan, power, temperature, voltage, and power-supply
redundancy
vCable-presence detection on most connectors

vSCSI activity LED: When this LED is lit, it indicates that there is activity on the
SCSI or IDE bus.
vPower-control button: Press this button to turn the server on and off manually.
Apower-control-button shield comes installed on the server to prevent the server
from being turned off accidentally.
vPower-on LED: When this LED is lit and not flashing, it indicates that the server
is turned on. When this LED is flashing, it indicates that the server is turned off
and still connected to an ac power source. When this LED is off, it indicates that
ac power is not present, or the power supply or the LED itself has failed.
