Using
the
integrated
management
module
The
integrated
management
module
(IMM)
is
a
second
generation
of
the
functions
that
were
formerly
provided
by
the
baseboard
management
controller
hardware.
It
combines
service
processor
functions,
video
controller,
and
(when
IMM
Premium
is
installed)
remote
presence
function
in
a
single
chip.
The
IMM
supports
the
following
basic
systems-management
features:
v
Environmental
monitor
with
fan
speed
control
for
temperature,
voltages,
fan
failure,
and
power
supply
failure.
v
EasyLED
diagnostics
LEDs
indicators
to
report
errors
that
occur
with
fans,
power
supplies,
microprocessor,
hard
disk
drives,
and
system
errors.
v
DIMM
error
assistance.
The
Unified
Extensible
Firmware
Interface
(UEFI)
disables
a
failing
DIMM
that
is
detected
during
POST,
and
the
IMM
lights
the
associated
system
error
LED
and
the
failing
DIMM
error
LED.
v
System
event
log
(SEL).
v
ROM-based
IMM
firmware
flash
updates.
v
Auto
Boot
Failure
Recovery
(ABR).
v
IMM
Premium,
which
enables
remote
presence
support
(remote
video,
remote
keyboard/mouse,
and
remote
storage).
v
Automatic
microprocessor
disable
on
failure
and
restart
in
a
two-microprocessor
configuration
when
one
microprocessor
signals
an
internal
error.
When
one
of
the
microprocessors
fail,
the
server
will
disable
the
failing
microprocessor
and
restart
with
the
other
microprocessor.
v
Nonmaskable
interrupt
(NMI)
detection
and
reporting.
v
Automatic
Server
Restart
(ASR)
when
POST
is
not
complete
or
the
operating
system
hangs
and
the
operating
system
watchdog
timer
times-out.
The
IMM
might
be
configured
to
watch
for
the
operating
system
watchdog
timer
and
reboot
the
system
after
a
timeout,
if
the
ASR
feature
is
enabled.
Otherwise,
the
IMM
allows
the
administrator
to
generate
a
nonmaskable
interrupt
(NMI)
by
pressing
an
NMI
button
on
the
system
board
for
an
operating-system
memory
dump.
ASR
is
supported
by
IPMI.
v
Intelligent
Platform
Management
Interface
(IPMI)
Specification
V2.0
and
Intelligent
Platform
Management
Bus
(IPMB)
support.
v
Invalid
system
configuration
(CNFG)
LED
support.
v
Serial
port
redirection
over
telnet
or
ssh.
v
Serial
over
LAN
(SOL).
v
Active
Energy
Manager.
v
Query
power-supply
input
power.
v
PECI
2
support.
v
Power/reset
control
(power-on,
hard
and
soft
shutdown,
hard
and
soft
reset,
schedule
power
control).
v
Alerts
(in-band
and
out-of-band
alerting,
PET
traps
-
IPMI
style,
SNMP,
e-mail).
v
Operating-system
failure
blue
screen
capture.
v
Command-line
interface.
v
Configuration
save
and
restore.
v
PCI
configuration
data.
v
Boot

The
IMM
also
provides
the
following

server
management
capabilities:
