Chapter 1. Introducing the IBM xSeries 240 3

What your server offers
The unique design of your IBM xSeries 240 takes advantage of advancements in
symmetric multiprocessing (SMP), data storage, and memory management. Your
server combines:
Impressive performance using an innovative approach to SMP
Your server supports up to two Pentium III microprocessors. Your server
comes with one microprocessor installed; you can install an additional
microprocessor to enhance performance and provide SMP capability.
Large data-storage and hot-swap capabilities
All models of the server support up to six hot-swap hard disk drives. This
hot-swap feature enables you to remove and replace hard disk drives without
turning off the server.
Hot-plug PCI adapter capabilities
Your server has three hot-plug slots for PCI adapters. This feature is
sometimes referred to as Active PCI. With operating system support, you can
replace failing hot-plug PCI adapters without turning off the server. If the
hot-add feature is supported by your operating system and the PCI adapter,
you can also add PCI adapters in these slots without turning off the server.
Redundant cooling and power capabilities
The redundant cooling and hot-swap capabilities of the fans in your server
allow continued operation if one of the fans fails. You can also replace a failing
fan without turning off the server.
The two 250-watt power supplies in your server provide redundant power for
many configurations of your server. If the average load on your server is less
than 250 watts and a problem occurs with one of the power supplies, the other
power supply can handle the load. For power loads above 250 watts, you can
install a third, optional power supply to provide a full 500 watts of power. The
NON REDUNDANT light emitting diode (LED) on the diagnostic LED panel is lit
when the power load is 250 watts or greater with two power supplies installed.
Large system memory
The memory bus in your server supports up to 4GB of system memory. The
memory controller provides error correcting code (ECC) support for up to four
industry-standard PC133, 3.3 V, 168-pin, 8-byte, registered,
synchronous-dynamic-random access memory (SDRAM) DIMMs (Intel
PC-Registered SDIMM Specifications, Revision 1.0 or later), synchronous, dual
inline memory modules.
4IBM xSeries User's Reference

System-management capabilities
Your server comes with an Advanced System Management Processor on the
system board. This processor, in conjunction with the systems-management
software provided with your server, allows you to manage the functions of the
server locally and remotely. The Advanced System Management Processor
also provides system monitoring, event recording, and dial-out alert capability.
Note: The Advanced System Management Processor is sometimes referred to
as the service processor.
Refer to the information provided with the systems-management software for
more information.
Integrated network environment support
Your server comes with an Ethernet controller on the system board. This
Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps
networks. The server automatically selects between 10BASE-T and
100BASE-TX. The controller provides full-duplex (FDX) capability, which allows
simultaneous transmission and reception of data on the Ethernet local area
network (LAN).
Redundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a
failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.
IBM ServerGuide CDs
The ServerGuideCDs included with your server provide programs to help you
set up your server and install the network operating system (NOS). The
ServerGuide program detects the hardware options installed and provides the
correct configuration program and device drivers. For more information, see
the ServerGuide topic provided on the IBM xSeries Documentation CD.
Your server is designed to be cost-effective, powerful, and flexible. It uses
peripheral component interconnect (PCI) bus architecture to provide compatibility
with a wide range of existing hardware devices and software applications.
As always, your IBM server meets stringent worldwide certifications for power,
electromagnetic compatibility (EMC), and safety.
Chapter 1. Introducing the IBM xSeries 240 5

Reliability, availability, and serviceability features
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored
on your server; that your server is available when you want to use it; and that
should a failure occur, you can easily diagnose and repair the failure with minimal
inconvenience.
