What your server offers

Your server uses the following features and technologies:

Device Driver and IBM Enhanced Diagnostics

start the Enhanced Diagnostics diagnostic programs, press F2 while the

server is starting.

Baseboard management controller

The baseboard management controller (BMC) is a service processor that
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.

IBM Director

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

IBM 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/pc/us/eserver/xseries/xarchitecture/enterprise/index.html.

Active

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 a failed pair of
DIMMs from the system configuration and activates a pair of online-spare
DIMMs. For more information, see the section about installing DIMMs in the
IBM xSeries 336 Type 8837 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 PC3200, 400 MHz, 1.8 V, 184-pin, registered,
double-data-rate (DDR), synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs).

Memory ProteXion

The Memory ProteXion feature provides a function that is similar to a
hot-spare drive in a RAID array. It is based in the memory controller, and it
enables the server to sense when a chip on a DIMM has failed and to route
the data around the failed chip.

v

IBM ServerGuide

The ServerGuide Setup and Installation CD that comes with the server provides
programs to help you set up the server and install a 32-bit Windows
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 21.

Integrated network support

The server comes with an integrated Broadcom Gigabit Ethernet controller, which
supports connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network. For more
information, see “Configuring the Gigabit Ethernet controller” on page 23.

Large data-storage capacity and hot-swap capability

The server supports up to four 2.5-inch or two 25.4-mm (1-inch) slim-high, 3.5
inch SCSI hot-swap hard disk drives in the hot-swap bays. With the hot-swap
feature, you can add, remove, or replace hard disk drives without turning off the
server.

This server also supports two 25.4-mm (1-inch) slim-high, 3.5-inch SATA simple
swap hard disk drives.

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 Installation Guide.

Redundant connection

The addition of an optional network interface card (NIC) provides failover
capability to a redundant Ethernet connection. If a problem occurs with the
primary Ethernet connection, all Ethernet traffic that is associated with the
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.

Redundant cooling and optional power capabilities

The redundant cooling of the fans in the server enables continued operation if
one of the fans fails. The server comes with one 585-watt hot-swap power
supply. You can order a second optional power supply, which provides redundant
power for many server configurations.

ServeRAID

™

support

The server supports ServeRAID adapters to create redundant array of
independent disks (RAID) configurations.

Symmetric multiprocessing (SMP)

The server supports up to two Intel microprocessors. If the server comes with
only one microprocessor, you can install an additional microprocessor to enhance
performance and provide SMP capability.

Systems-management capabilities

The server comes with a baseboard management controller (BMC) installed.
When used with the systems-management software that comes with the server,
you can manage the functions of the server locally and remotely. The BMC also
provides system monitoring, event recording, and dial-out alert capability.

The optional Remote Supervisor Adapter II SlimLine can be used to obtain
enhanced system management capabilities, above those of the embedded BMC.
The Remote Supervisor Adapter II SlimLine, when installed, has a dedicated
Ethernet connection at the rear of the server.

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

stored in the server, the availability of the server when you need it, and the ease

with which you can diagnose and correct problems.

Your server has the following RAS features:

Active

Memory is an IBM feature that improves the reliability of memory through

memory mirroring and the Memory ProteXion

Memory ProteXion

detected error is recoverable, the Memory ProteXion feature corrects the error
and rewrites the data to another memory location on the same DIMM. If there are
not sufficient undamaged memory locations that the data can be rewritten to, the
error is unrecoverable. Other conditions can also cause unrecoverable errors. If a
detected error is unrecoverable, light path diagnostics LEDs are lit to indicate the
failing DIMM.

You do not have to enable memory mirroring to use the Memory ProteXion feature.

Memory mirroring and sparing

Memory mirroring stores data in memory pair 1 and 2 and memory pair 3 and 4
simultaneously. To support memory mirroring, you must install identical dual inline
memory modules (DIMMs) in memory pair 1 and 2 and memory pair 3 and 4. For
more information, see the section about installing memory modules in the Option

Installation Guide on the IBM xSeries Documentation CD.

The server also supports memory sparing; however, the sparing feature is mutually
exclusive with mirroring. The sparing feature disables the failed memory from the
system configuration and activates a memory sparing pair of DIMMs to replace the
failed active DIMM pair.

Before you can enable the memory sparing feature, you must install one additional
pair of DIMMs. The memory sparing DIMM pair must be the same speed, type, and
the same size as or larger, than the active DIMM pair.

enable memory mirroring or sparing through the Configuration/Setup Utility

program, select Advanced Setup from the main menu, and select Memory
Configuration. For more information about using the Configuration/Setup Utility
program, see “Using the Configuration/Setup Utility program” on page 16.

depending on the hardware configuration you have.

Hot-swap hard disk drive activity LED: This LED is used on SCSI hard disk

drives. Each hot-swap hard disk drive has an activity LED, and when this LED is
flashing, it indicates that the drive is in use.

Hot-swap hard disk drive status LED: This LED is used on SCSI hard disk

drives. When this LED is lit, it indicates that the drive has failed. If an optional
IBM ServeRAID controller is installed in the server, when this LED is flashing
slowly (one flash per second), it indicates that the drive is being rebuilt. When the
LED is flashing rapidly (three flashes per second), it indicates that the controller
