IBM xSeries 342: User’s Reference
• Large system memory
The memory bus in your server supports up to 4GB (GB equals approximately
1 000 000 000 bytes) of two-way interleaved 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) dual inline memory modules (DIMMs).
• Integrated System Management (ISM) Processor
The IBM Integrated System Management Processor provides environmental
monitoring for your server. This system environmental monitor supports the
Automatic Server Restart (ASR) feature, and it can issue system alerts using the
Alert on LAN features of the integrated Ethernet controller. Future firmware code
releases for the Integrated System Management Processor will support additional
functions and features. These features will include dial-in support using the
dedicated system management serial port C, alert forwarding through the
integrated system management (ISM) connectors, error logging, support for
communication between the Integrated System Management Processor and
more robust IBM system management adapters and controllers.
• 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.
• Optional digital linear tape drive
The addition of an optional digital linear tape drive (DLT) allows quick backup of
large amounts of data.
• 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 programs and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for your server. See Chapter 4, “Using
the ServerGuide CDs,” on page 21 for more information.
Reliability, availability, and serviceability features
RAS feat ures 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.
The following is an abbreviated list of the RAS features that your server supports.
• Menu-driven setup, system configuration, RAID configuration, and diagnostic
programs
• Power-on self-test (POST)
