where
other
Remote
Supervisor
Adapters,
ASM
processors,
and
ASM
PCI
Adapters
on
the
network
reside.
Second,
the
ASM
interconnect
network
enables
other
interconnect
network
devices
to
use
the
resources
(Ethernet
or
modem)
of
other
Remote
Supervisor
Adapters,
ASM
processors,
and
ASM
PCI
Adapters
in
the
ASM
interconnect
network
for
sending
alerts.
This
interconnect
network
is
used
when
Remote
Supervisor
Adapters,
ASM
processors,
or
ASM
PCI
Adapters
cannot
send
an
alert
and
must
forward
the
information
to
another
one
of
these
devices
to
send
the
alert.
Planning
and
cabling
the
interconnect
network:
To
support
the
most
recent
ASM
features,
a
Remote
Supervisor
Adapter
must
be
the
main
gateway
interconnect
to
the
ASM
interconnect
bus
if
the
bus
also
includes
servers
with
ASM
PCI
adapters
or
ASM
processors.
The
Remote
Supervisor
Adapter
forwards
the
ASM
information
generated
by
the
servers
attached
to
the
ASM
interconnect
bus
to
other
servers
on
the
Ethernet
network.
The
connected
ASM
processors
and
ASM
PCI
Adapters
are
managed
through
the
new
user
interface
and
Web
browser
access
of
the
Remote
Supervisor
Adapter.
Note:
To
ensure
the
stability
of
the
system,
you
must
have
the
most
current
level
of
firmware
installed
on
the
Remote
Supervisor
Adapter
that
is
the
main
interconnect
gateway
for
the
ASM
interconnect
network.
The
most
current
level
of
firmware
is
available
on
the
World
Wide
Web
at
http://www.ibm.com/pc/support/.
For
more
information
on
updating
firmware,
see
the
IBM
Remote
Supervisor
Adapter
User’s
Guide
on
the
IBM
xSeries
Documentation
CD.
You
must
connect
an
ASM
Interconnect
module
to
the
Remote
Supervisor
Adapter
and
to
each
xSeries
445
server
that
you
connect
to
the
ASM
interconnect
network
bus.
Attention:
To
avoid
damage
to
the
Ethernet
connector
on
the
Remote
Supervisor
Adapter,
do
not
connect
the
ASM
Interconnect
module
to
the
Remote
Supervisor
Adapter
Ethernet
port.
To
connect
the
servers,
note
the
following
setup
and
configuration
considerations:
v
Make
sure
that
the
ASM
interconnect
network
is
set
up
as
a
bus,
not
as
a
ring.
You
must
connect
the
servers
to
the
ASM
interconnect
network
in
a
series,
with
terminated
beginning
and
end
points.
v
Make
sure
that
the
total
combined
length
of
all
Ethernet
cables
connecting
the
server
in
the
ASM
interconnect
network
does
not
exceed
91
M
(300
ft).
v
Each
Remote
Supervisor
Adapter,
ASM
PCI
adapter,
or
ASM
processor
that
is
connected
to
the
ASM
interconnect
network
bus
counts
as
one
connection.
For
example,
if
an
ASM
PCI
adapter
is
installed
in
a
server
that
has
an
ASM
processor,
the
processor
and
the
adapter
connect
to
each
other
using
one
ASM
interconnect
connection,
but
the
processor
and
the
adapter
count
as
two
connections
on
the
ASM
interconnect
network
bus.
Forwarding
alerts:
Remote
Supervisor
Adapters,
ASM
PCI
adapters,
and
ASM
processors
that
are
connected
to
an
ASM
interconnect
network
share
resources
and
system-management
information.
This
section
provides
information
on
how
alerts
are
forwarded
in
the
ASM
interconnect
network.
During
normal
operation,
each
Remote
Supervisor
Adapter,
ASM
processor,
or
ASM
PCI
adapter
on
the
ASM
interconnect
network
communicates
with
the
other
processors
and
adapters
on
the
network.
Processors
or
adapters
that
have
a
modem
or
Ethernet
connection
notify
the
other
processors
and
adapters
that
