Revision 1.0

3.5 Intel
®
ASMI
Connector
The
server board RMM
connector
implements
two
Fast
Management
Link
(FML)
interfaces:
BMC_FML_0
NIC_FML_1
Both
FML
interfaces
are
wired
to
the
FPGA
of
the
Intel
®
RMM2.
However,
only
the
Intel RMM2
uses
the
BMC_FML_0.
The
FML
bus
is
a
high-speed
(8
Mb/S)
point-to-point
interface
that
utilizes
a
single
master
and
a
single
slave.
The
BMC
is
the
FML
master
and
the
Intel
®
RMM2
is
the
FML
slave.
3.5.1 BMC_FML_0 Interface
BMC_FML_0
provides
a
high-speed
interface
between
the
BMC
on
the
server board
and
the
Intel RMM2.
Through
this
interface,
the
Intel RMM2
forwards
IPMI
2.0
traffic
(UDP/IP
traffic
to
specific
RMCP
ports)
to
the
BMC.
The
forwarded
traffic
is
received
from
the
network
on
the
dedicated
NIC.
IPMI
return
traffic
is
transmitted
by
the
BMC
to
the
Intel
®
RMM
NIC
on
the
FML,
as
well.
3.5.2
FML
Connection
The
FML
connection
with
the
Intel RMM2
resembles
a
LAN
channel
to
the
server board
BMC.
The Intel
®
RMM2
acts
as
an
FML
slave
device
to
the
FML
master
within
the
BMC
on
the
server
board.
As
the
FML
slave,
the
Intel
®
RMM2
controls
the
SINTEX
interrupt
line.
This
interrupt
is
used
to
signal
the
BMC
whenever
the
Intel RMM2
wishes
to
initiate
an
FML
data
transfer
of
any
kind.
3.5.3 NIC_FML_1
NIC_FML_1
is
not
used
by
the
Intel
®
RMM2, but
it
is
connected
from
the
server board RMM
connector
to
pins
on
the
FPGA.
This
could
be
used
to
connect
the
Intel RMM2
to
a
server board
Intel
®
RMM
NIC
using
the
FML
bus
instead
of
the
MII
interface.
This
scheme
is
referred
to
as the
FML/TCO
management
port.
