information about the ServerGuide Setup and Installation CD, see "Using the ServerGuide Setup and Installation CD" on page 54. v Impressive performance using the latest microprocessor technology Your blade server supports up to four Intel Xeon microprocessors. Your blade server comes with at least one microprocessor installed; you can install additional microprocessors to further enhance performance and symmetric multiprocessing (SMP) capability. v I/O expansion Your blade server comes with two connectors on the I/O board for optional I/O expansion cards for adding more network communication capabilities to the blade server. v Integrated network support Your blade server comes with four integrated Gigabit Ethernet controllers. Each Ethernet controller has an interface for connecting to 10/100/1000-Mbps networks through an Ethernet switch module in the BladeCenter unit. The blade server automatically selects between 10BASE-T and 100/1000BASE-TX environments. Each controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). The controllers support Wake on LAN® technology. v Light path diagnostics Light path diagnostics provides LEDs to help you diagnose problems. For more information, see "Light path diagnostics" on page 72. v Serial over LAN Your blade server supports serial over LAN (SOL) technology, which provides advanced remote management capability. It provides the ability to redirect server serial data over a LAN without the use of serial concentrators. It also eliminates the need for serial cabling by internally rerouting serial packets over the LAN. The SOL feature is accessed through the management-module command-line interface. The SOL feature does not require any special client software because it is designed to work with existing standard Telnet consoles. See the BladeCenter Management Module Command-Line Interface User's Guide and the BladeCenter Serial Over LAN Setup Guide for information. v Symmetric multiprocessing (SMP) Your server supports up to four Intel microprocessors. If the server comes with only one microprocessor, you can install an additional microprocessor to enhance performance and provide SMP capability. Reliability, availability, and serviceability features 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 your server, the availability of the server when you need it, and the ease with which you can diagnose and repair problems. Your server has the following RAS features: v Advanced Configuration and Power Interface (ACPI) v Automatic server restart v Built-in monitoring for temperature, voltage, hard disk drives, and flash drives v Chipkill memory v Customer-upgradeable basic input/output system (BIOS) code Chapter 1.

v
Impressive
performance
using
the
latest
microprocessor
technology
Your
blade
server
supports
up
to
four
Intel
Xeon
microprocessors.
Your
blade
server
comes
with
at
least
one
microprocessor
installed;
you
can
install
additional
microprocessors
to
further
enhance
performance
and
symmetric
multiprocessing
(SMP)
capability.
v
I/O
expansion
Your
blade
server
comes
with
two
connectors
on
the
I/O
board
for
optional
I/O
expansion
cards
for
