Hot-swap
hard
disk
drive
activity
LED
(some
models)

server
models,
each
hot-swap

has

Hot-swap
hard
disk
drive
status
LED
(some
models)
On
hot-swap
server
models,
each
hot-swap
hard
disk
drive
has
a
amber
status
LED.
If
the
amber
status
LED
for
a
drive
is
lit
continuously,
it
indicates
that
the
individual
drive
is
faulty.
The
interpretation
of
a
flashing
amber
status
LED
depends
on
the
SCSI
controller
connected
to
the
hot-swap
drive,
as
follows:
When
the
drive
is
connected
to
an
optional
ServeRAID
controller,
a
slowly
flashing
(one
flash
per
second)
amber
status
LED
indicates
that
the
drive
is
being
rebuilt.
When
the
LED
is
flashing
rapidly
(three
flashes
per
second),
it
indicates
that
the
controller
is
identifying
the
drive.
