• Integrated network support
The server comes with an integrated dual-port Intel Gigabit Ethernet controller, which supports connection
to a 10 Mbps, 100 Mbps, or 1000 Mbps network. For more information, see "Configuring the Ethernet
controller" on page 75.
• Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and public secure
keys. It provides the hardware support for the Trusted Computing Group (TCG) specification. You
can download the software to support the TCG specification, when the software is available. See
http://www.ibm.com/systems/x/hardware/enterprise/index.html for details about the TPM implementation.
You can enable TPM support through the Setup utility under the System Security menu option (see
"Using the Setup utility" on page 64).
• Large data-storage capacity and hot-swap capability
The server supports a maximum of eight 2.5-inch hot-swap or simple-swap Serial Attached SCSI (SAS)
or Serial ATA (SATA) hard disk drives or four 3.5-inch hot-swap or simple-swap SATA hard disk drives,
depending on the server model.
• Large system-memory capacity
The server supports up to 32 GB if unbuffered DIMMs are installed. The memory controller supports
error correcting code (ECC) for up to 4 industry-standard PC3L-12800 (DDR3-1600 or DDR3-1333),
DDR3 (third-generation double-data-rate), unbuffered or synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs).
• Mobile access to IBM Service Information website
The server provides a QR code on the system service label, which is on the cover of the server, that you
can scan using a QR code reader and scanner with a mobile device to get quick access to the IBM
Service Information website. The IBM Service Information website provides additional information for
parts installation and replacement videos, and error codes for server support. For the QR code, see QR
code information on page Chapter 1 "The Lenovo System x3250 M4 Type 2583 server" on page 1.
• Multi-core processing
The server supports Intel Celecon™ and Xeon™ E3-1200 series multi-core microprocessors. The server
comes with one microprocessor installed.
• PCI adapter capabilities
The server has two PCI interface slots. Both slots can support PCI Express or PCI-X adapters through an
optional PCI-X interposer card. See "Replacing an adapter" on page 139 for detailed information.
• Redundant connection
The addition of the optional Ethernet adapter 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 adapter is installed on the server, all Ethernet traffic that is
associated with the primary connection is automatically switched to the optional redundant Ethernet
adapter connection. If the applicable device drivers are installed, this switching occurs without data loss
and without user intervention.
• Redundant cooling and optional power capabilities
The server supports a maximum of two 460-watt hot-swap power supplies and 5 fans, which provide
redundancy and hot-swap capability for a typical configuration. The redundant cooling by the fans in
the server enables continued operation if one of the fans fails. The server comes with the minimum of
one 460-watt hot-swap power supply and four fans. You can order the second optional power supply
for power redundancy.
• ServeRAID support
