AC power LED: This green LED provides status information about the power supply. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see "Light path diagnostics" on page 93. Power-cord connector: Connect the power cord to this connector. Ethernet Activity LED: This LED is on the Ethernet connector. When it flashes, it indicates that data is being transmitted or received between the server and the network device that is connected to the connector. The flashing frequency is proportional to the amount of traffic on the network link. ASM: Use this connector to connect the server to an Advanced System Management (ASM) network. Ethernet link status LED: This LED is on the Ethernet connector. When this LED is lit, there is an active connection on the Ethernet port. Remote Supervisor Adapter II SlimLine Ethernet: Use this connector to connect the server to an optional Remote Supervisor Adapter II SlimLine installed in another server. This connector is enabled when the Remote Supervisor II SlimLine option is installed. Server power features When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor is shut down; however, the server can respond to requests from the service processor (also called the baseboard management controller), such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but is not turned on. Turning on the server Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, one or more fans might start running, and you can turn on the server and start the operating system by pressing the power-control button. The server can also be turned on in any of the following ways: v If a power failure occurs while the server is turned on, the server will restart automatically when power is restored. v If the server is connected to an Advanced System Management interconnect network that contains at least one server with an optional Remote Supervisor Adapter installed, the server can be turned on from the Remote Supervisor Adapter user interface. v If your operating system supports the systems-management software for an optional Remote Supervisor Adapter, the systems-management software can turn on the server. v If your operating system supports the Wake on LAN® feature, the Wake on LAN feature can turn on the server.

AC
power
LED:
This
green
LED
provides
status
information
about
the
power
supply.
During
typical
operation,
both
the
ac
and
dc
power
LEDs
are
lit.
For
any

Power-cord
connector:
Connect
the
power
cord
to
this
connector.
Ethernet
Activity
LED:
This
LED
is
on
the
Ethernet
connector.
When
it
flashes,
it
indicates
that
data
is
being
transmitted
or
received
between
the
server
and
the
network
device
that
is
connected
to
the
connector.
The
flashing
frequency
is
proportional
to
the
amount
of
traffic
on
the
network
link.
ASM:
Use
this
connector
to
connect
the
server
to
an
Advanced
System
Management
(ASM)
network.
Ethernet
link
status
LED:
This
LED
is
on
the
Ethernet
connector.
When
this
LED
is
lit,
there
is
an
active
connection
on
the
Ethernet
port.
Remote
Supervisor
Adapter
II
SlimLine
Ethernet:
Use
this
connector
to
connect
the
server
to
an
optional
Remote
Supervisor
Adapter
II
SlimLine
installed
in
another
server.
This
connector
is
enabled
when
the
Remote
Supervisor
II
SlimLine
option
is
installed.
Server
power
features
When
the
server
is
connected
to
an
ac
power
source
but
is
not
turned
on,
the
operating
system
does
not
run,
and
all
core
logic
except
for
the
service
processor
is
shut
down;
however,
the
server
can
respond
to
requests
from
the
service
processor
(also
called
the
baseboard
management
controller),
such
as
a
remote
request
to
turn
on
the
server.
The
power-on
LED
flashes
to
indicate
that
the
server
is
connected
to
ac
power
but
is
not
turned
on.
Turning
on
the
server
Approximately
20
seconds
after
the
server
is
connected
to
ac
power,
the
power-control
button
becomes
active,
one
or
more
fans
might
start
running,
and
you
can
turn
on
the
server
and
start
the
operating
system
by
pressing
the
power-control
button.
The
server
can
also
be
turned
on
in
any
of
the
following
ways:
v
If
a
power
failure
occurs
while
the
server
is
turned
on,
the
server
will
restart
automatically
when
power
is
restored.
v
If
the
server
is
connected
to
an
Advanced
System
Management
interconnect
network
that
contains
at
least
one
server
with
an
optional
Remote
Supervisor
Adapter
installed,
the
server
can
be
turned
on
from
the
Remote
Supervisor
Adapter
user
interface.
v
If
your
operating
system
supports
the
systems-management
software
for
an
optional
Remote
Supervisor
Adapter,
the
systems-management
software
can
turn
on
the
server.
v
If
your
operating
system
supports
the
Wake
on
LAN
®
feature,
the
Wake
on
LAN
feature
can
turn
on
the
server.
