server
offers
Your
server
uses
the
following
features
and
technologies:
v
Device
Driver
and
IBM
Enhanced
Diagnostics
To
start
the
Enhanced
Diagnostics
diagnostic
programs,
press
F2
while
the
server
is
starting.
v
Baseboard
management
controller
The
baseboard
management
controller
(BMC)
is
a
service
processor
that
provides
environmental
monitoring
for
the
server.
If
environmental
conditions
exceed
thresholds
or
if
system
components
fail,
the
baseboard
management
controller
lights
LEDs
to
help
you
diagnose
the
problem.
Critical
errors
are
also
included
in
the
error
log.
v
IBM
Director
IBM
Director
is
a
workgroup-hardware-management
tool
that
you
can
use
to
centrally
manage
xSeries
servers.
For
more
information,
see
the
IBM
Director
documentation
on
the
IBM
Director
CD.
v
IBM
Enterprise
X-Architecture
technology
IBM
X-Architecture
technology
combines
proven,
innovative
IBM

Active
™
Memory
The
Active
Memory
feature
improves
the
reliability
of
memory
through
memory
mirroring,
and
online-spare
memory.
Memory
mirroring
stores
data
in
two
pairs
of
DIMMs
simultaneously.
Online-spare
memory
disables
a
failed
pair
of
DIMMs
from
the
system
configuration
and
activates
a
pair
of
online-spare
DIMMs.
For
more
information,
see
the
section
about
installing
DIMMs
in
the
IBM
xSeries
336
Type
8837
Installation
Guide
.
–
Large
system-memory
capacity
The
memory
bus
supports
up
to
16
GB
of
system
memory.
The
memory
controller
supports
error
correcting
code
(ECC)
for
up
to
eight
industry-standard
PC3200,
400
MHz,
1.8
V,
184-pin,
registered,
double-data-rate
(DDR),
synchronous
dynamic
random
access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
–
Memory
ProteXion
The
Memory
ProteXion
feature
provides
a
function
that
is
similar
to
a
hot-spare
drive
in
a
RAID
array.
It
is
based
in
the
memory
controller,
and
it
enables
the
server
to
sense
when
a
chip
on
a
DIMM
has
failed
and
to
route
the
data
around
the
failed
chip.
v
IBM
ServerGuide
™
Setup
and
Installation
CD
The
ServerGuide
Setup
and
Installation
CD
that
comes
with
the
server
provides
programs
to
help
you
set
up
the
server
and
install
a
32-bit
Windows
®
operating
system.
The
ServerGuide
program
detects
installed
hardware
options
and
provides
the
correct
configuration
programs
and
device
drivers.
For
more
information
about
the
ServerGuide
Setup
and
Installation
CD,
