inside the RAID controller that you are replacing and install them in the replacement RAID controller. The steps to remove and install the battery and DIMM are included in the following procedure. 2. The RAID controller in the DS300 model 1701-1RL does not contain a cache battery. Replacing the hardware To replace a failed controller, complete the following steps: 1. For a single-controller DS300 or DS400 storage subsystem only: Turn off the storage subsystem. 2. Label each cable that is connected to the failed controller to be sure that all cables are reconnected correctly later in the procedure. 3. Remove all Ethernet cables from the failed controller. 4. For a Fibre Channel RAID controller only: Remove the fiber-optic cables and the SFP modules from the failed controller. For information about removing the fiber-optic cables and SFP modules, refer to the ″Hardware Installation and User's Guide″. 5. Remove the failed controller (the fault LED is lit): a. While squeezing together the latch and lever that are on each side of the controller, press down on the orange area on each latch. The controller slides out of the bay a short distance. b. Grasp both latches and pull the controller out of the bay. c. Place the controller on a dry, level surface. Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling static-sensitive devices, see "Handling static-sensitive devices" on page 35. 6. Remove the cache battery from the failed controller. Battery Thumbscrew a. Loosen the thumbscrew that holds the battery in place. b. Hold down the edge of the controller base on the battery side (near the thumbscrew). c. Pull up on the blue lift tab on the battery to remove it from the connector. d. Slide the battery toward the open end of the controller to remove it. e. Place the battery on a dry, level surface. 7. Unpack the replacement controller and set it on a dry, level surface. Save the packing material and documentation in case you have to return the controller. 8. Install the battery (that you removed in step 6) into the replacement controller. Appendix A. Installing and replacing components 49

inside
the
RAID
controller
that
you
are
replacing
and
install
them
in
the
replacement
RAID
controller.
The
steps
to
remove
and
install
the
battery
and
DIMM
are
included
in

1701-1RL
does
not
contain
a
cache
battery.
Replacing
the
hardware
To
replace
a
failed
controller,
complete
the
following
steps:
1.
For
a
single-controller
DS300
or
DS400
storage
subsystem
only:
Turn
off
the
storage
subsystem.
2.
Label
each
cable
that
is
connected
to
the
failed
controller
to
be
sure
that
all
cables
are
reconnected
correctly
later
in
the
procedure.
3.
Remove
all
Ethernet
cables
from
the
failed
controller.
4.
For
a
Fibre
Channel
RAID
controller
only:
Remove
the
fiber-optic
cables
and
the
SFP
modules
from
the
failed
controller.
For
information
about
removing
the
fiber-optic
cables
and
SFP
modules,
