drive
activity
LED
(some
models)
On
some
server
models,
each
hot-swap
drive
has
a
hard
disk
drive
activity
LED.
When
this
green
LED
is
flashing,
it
indicates
that
the
associated
hard
disk
drive
is
in
use.
When
the
drive
is

this
LED
also
is
visible
on
the
SAS/SATA
backplane,
next
to
the
drive
connector.
The

is
the

drive
status
LED
(some
models)
On
some
server
models,
each
hot-swap
hard
disk
drive
has
an
amber
status
LED.
If
this
amber
status
LED
is
lit,
it
indicates
that
the

failed.
If
an

is
installed
in
the

slowly
(one

also
is
visible
on
the
