Rear view Hot-swap hard disk drive activity LED (some models) On SCSI hot-swap server models, each hot-swap drive has a hard disk drive activity LED. When this green LED is flashing, it indicates that the drive is in use. Hot-swap hard disk drive status LED (some models) On SCSI hot-swap server models, each hot-swap hard disk drive has an amber status LED. If the status LED for a drive is lit continuously, it indicates that the individual drive is faulty. The interpretation of a flashing status LED depends on the SCSI controller that is connected to the hot-swap drive, as follows: When the drive is connected to an optional ServeRAID™ adapter, a slowly flashing (one flash per second) status LED indicates that the drive is being rebuilt. When the LED is flashing rapidly (three flashes per second), it indicates that the controller on the adapter is identifying the drive. Ethernet transmit/receive activity LED This LED is on the Ethernet connector. When this LED is lit, it indicates that there is activity between the server and the network. Ethernet link status LED This LED is on the Ethernet connector on the back of the server. When this LED is lit, it indicates that there is an active connection on the Ethernet port. The following illustration shows the connectors on the rear of the server.

Hot-swap
hard
disk
drive
activity
LED
(some
models)
On
SCSI
hot-swap
server
models,
each
hot-swap
drive
has
a
hard
disk
drive
activity
LED.
When
this
green
LED
is
flashing,
it
indicates
that
the
drive
is
in
use.
Hot-swap
hard
disk
drive
status
LED
(some
models)
On
SCSI
hot-swap
server
models,
each
hot-swap
hard
disk
drive
has
an
amber
status
LED.
If
the
status
LED
for
a
drive
is
lit
continuously,
it
indicates
that
the
individual
drive
is
faulty.
The
interpretation
of
a
flashing
status
LED
depends
on
the
SCSI
controller
that
is
connected
to
the
hot-swap
drive,
as
follows:
When
the
drive
is
connected
to
an
optional
ServeRAID
™
adapter,
a
slowly
flashing
(one
flash
per
second)
status
LED
indicates
that
the
drive
is
being
rebuilt.
When
the
LED
is
flashing
rapidly
(three
flashes
per
second),
it
indicates
that
the
controller
on
the
adapter
is
identifying
the
drive.
Ethernet
transmit/receive
activity
LED
This
LED
is
on
the
Ethernet
connector.
When
this
LED
is
lit,
it
indicates
that
there
is
activity
between
the
server
and
the
network.
Ethernet
link
status
LED
This
LED
is
on
the
Ethernet
connector
on
the
back
of
the
server.
When
this
LED
is
lit,
it
indicates
that
there
is
an
active
connection
on
the
Ethernet
port.
