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. For more information, see the IBM BladeCenter and BladeCenter T Serial Over LAN Setup Guide and BladeCenter and BladeCenter T Management Module Command-Line Interface Reference Guide. Reliability, availability, and serviceability features Three important features in server design are reliability, availability, and serviceability (RAS). These RAS features are designed to help you protect the integrity of the data stored on your blade server; help ensure that your blade server is available when you want to use it; and, in the event of a failure, help you easily diagnose and repair the failure with minimal inconvenience. The following is a list of some of the RAS features that your blade server supports: v Automatic error retry or recovery v Automatic server restart v Built-in monitoring for temperature, voltage, and hard disk drives v Customer-upgradeable system firmware code v Customer support center 24 hours per day, 5 days a week (Monday through Friday)2 v Diagnostic support of Ethernet controller ports v Error codes and messages v ECC protection on the Level 2 (L2) cache v ECC memory v Light path diagnostics v Power-on self-test (POST) v Predictive Failure Analysis (PFA) alerts v Service processor that communicates with the BladeCenter management module to enable remote blade server management v SDRAM with serial presence detect (SPD) and vital product data (VPD) v System error logging v VPD (includes information stored in nonvolatile memory for easier remote viewing) v Wake on LAN capability 2. Service availability will vary by country. Response time will vary depending on the number and nature of incoming calls. Chapter 1. Introduction 9

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.
