Working
with
hot-swap
RAID
controllers
(dual-controller
models
only)
Each
RAID
controller
fits
into
the
back
of
the
storage
subsystem
and
has
the
following
components:
v
Battery
v
Cache
memory
v
Two
host
ports
and
one
expansion
port
v
One
Ethernet
port
v
One
serial
port
Exception:
The
DS4300
single-controller
storage
subsystem
(Model
6LU/6LX)
has
only
one
RAID
controller.
Therefore,
you
cannot
hot
swap
the
RAID
controller.
Each
RAID
controller
has
a
unique
hardware
Ethernet
address,
which
is
printed
on
a
label
on
the
front.
There
is
also
a
label
giving
the
cache
battery
manufacturing
and
installation
dates
on
the
top
of
the
controller
unit.
