BIOS recovery
Refer
to
the
Firmware
and
Software
Update
Instructions
for
the
full
BIOS
image
upload
procedure.
If
the
CPM
BIOS
fails
boot
due
to
Flash
corruption
of
both
the
primary
and
secondary
boot
Flash
images,
the
user
can
recover
the
Flash
BIOS
image
using
a
BIOS
crisis
recovery
procedure.
When
the
“BIOS
Force
Recovery”
jumper
(pins
5
‐
6)
is
installed
in
the
customer
header
(P2),
the
BIOS
images
can
be
reloaded.
Refer
to
Onboard
headers
on
page 114
for
the
full
pinout
of
the
CPM
customer
header.
Once
the
recovery
mode
is
entered,
the
system
BIOS
tries
to
find
and
load
a
BIOS
image
from
either
the
front
panel
USB
port
or
the
front
panel
serial
port.
Once
the
BIOS
image
is
loaded
successfully,
the
system
BIOS
continues
the
subsequent
boot
phases
from
the
loaded
BIOS
image
until
the
BIOS
image
in
the
flash
device
is
re
‐
programmed.
The
main
and
NVRAM
BIOS
blocks
are
updated,
but
not
the
boot
block.
Contact
Radisys
Technical
Support
for
assistance
or
if
the
entire
BIOS
image
(including
the
boot
block)
needs
to
be
reloaded.
IPMC functions
The
IPMC
controls
the
hardware
management
subsystem
by
enabling
payload
power
and
ports,
detecting
component
hardware
states,
initiating
resets,
and
monitoring
managed
sensors.
The
CPM’s
hardware
management
system
complies
with
the
PICMG
3.0
R3.0
base
specification,
the
HPM.1
R1.0
firmware
upgrade
specification,
and
the
Intelligent
Platform
Management
Interface
(IPMI)
1.5
specification,
which
defines
a
set
of
common
interfaces
for
managing
the
system
and
for
monitoring
system
health.
Using
serial
‐
over
‐
LAN
and
IPMI
‐
over
‐
LAN
communications,
the
IPMC
provides
a
remote
user
with
access
to
the
CPU
serial
console
through
the
base
interface.
For
more
information,
see
Chapter
4,
IPMI
‐
Over
‐
LAN,
on
page 63
and
Serial
‐
Over
‐
LAN
on
page 65.
The
CPM's
CPU
communicates
with
the
IPMC
through
a
keyboard
controller
style
(KCS)
interface,
which
provides
access
to
IPMI
functions.
This
allows
the
CPU
to
send
messages
to
the
CPM's
IPMC
or
to
any
other
management
controller
in
the
shelf.
For
a
list
of
the
IPMI
commands
and
details
on
the
sensors
used
on
the
CPM,
refer
to
Appendix
B,
IPMI
Commands
and
Managed
Sensors,
on
page 86.
Software/Firmware Update Support
Software
or
firmware
update
instructions
are
included
in
each
update

In
the
case
of
a
downloaded
update
package,
any
update
instructions
are
included
as
a
separate
document
in
the
package.
When
the
software/firmware
update
is
provided
on
an
update
CD
ROM
(ISO)
image,
the
update
instructions
are
included
as
a
separate
