unit
for
the
two
local
area
network
(Ethernet)
connections,
as
driven
from
each
management
module,
and
the
telco
external
alarms.
This
module

LAN-module
connectors:
v
Remote
management
and
console
(Ethernet)
connectors:
The
LAN
module
provides
two
Ethernet
RJ-45
connectors.
The
BladeCenter
T
LAN
module
contains
two
10/100
Mb
Ethernet
connectors
that
provide
the
remote
connections,
driven
from
each
management
module,
to
the
network
management
station
on
the
network.
Use
these
ports
for
remote
management
and
remote
console.
The
network
management
station,
through
these
connectors,
can
access
control
functions
running
in
the
management
module,
the
service
processor
on
each
blade
server,
or
within
each
switch
module.
However,
it
cannot
use
these
ports
to
communicate
with
application
programs
running
in
the
blade
servers.
The
network
management
station
must
direct
those
communications
through
a
network
connected
to
the
external
ports
in
the
I/O
modules
in
the
BladeCenter
T
unit.
v
Alarms
connector:
The
LAN
module
provides
one
telco
DB15
alarms
connector
(male)
for
critical,
major,
and
minor
telco
alarms.
Each
of
the
alarms
has
a
relay
that
enables
multiple
system
alarm
indicators
to
be
daisy-chained
together.
Table

shows
the
pinouts
for
the
telco
alarms
connector.
