and 10 on page 50 for the procedure to replace the 512 MB system DIMM on the replacement controller with the 1 GB system DIMM from the failed controller. 11. Install the replacement controller: a. Make sure that the lever on each side of the controller is down as far as it will go. b. Push the controller into the bay until it meets resistance (approximately 6 mm [0.25 in.] from the end of the chassis). c. While squeezing together the latch and lever, push both latches up as far as they will go. The controller slides the rest of the way into the bay. 12. Reconnect the Ethernet cables that were disconnected in step 3 on page 49. 13. For a Fibre Channel RAID controller only: Insert the SFP modules and fiber-optic cables that you removed in step 4 on page 49. 14. Turn on the storage subsystem if you turned it off in step 1 on page 49. Configuring the management port To configure the management port, complete the following steps: 1. Open a Telnet session: v For a single-controller DS300 or DS400: Open a Telnet session to the default IP address 192.168.70.123. v For a dual-controller DS300 or DS400: Open a Telnet session to the IP address of the active controller. 2. At the command prompt, enter administrator. 3. At the password prompt, enter your administrator password. Note: The default administrator password is passw0rd (all lowercase letters with a zero, not O, in passw0rd). Complete the following two steps for a dual-controller DS300 or DS400 storage subsystem only: 4. At the command prompt, enter controller peer enable. 5. To determine whether the peer controller is ready, enter controller information. The peer controller is working correctly if the peer controller status is Ready. 6. For all storage subsystems: When the peer controller is ready, change the IP address and netmask address of the replacement controller to match your previous management port settings: v For a single-controller DS300 or DS400: To change the IP address, enter interface manage eth0 ip IP_address_of_failed_controller To change the netmask address, enter interface manage eth0 netmask network_mask_of_failed_controller Note: For a single-controller storage subsystem, when you change the IP address for the management port, you must establish a new Telnet session to the new IP address. v For a dual-controller DS300 or DS400: To change the IP address, enter interface manage eth0[x] ip IP_address_of_failed_controller To change the netmask address, enter interface manage eth0[x] netmask network_mask_of_failed_controller Appendix A.

for
the
procedure
to
replace
the
512
MB
system
DIMM
on
the
replacement
controller
with
the
1
GB
system
DIMM
from
the
failed
controller.
11.
Install
the
replacement
controller:
a.
Make
sure
that
the
lever
on
each
side
of
the
controller
is
down
as
far
as
it
will
go.
b.
Push
the
controller
into
the
bay
until
it
meets
resistance
(approximately
6
mm
[0.25
in.]
from
the
end
of
the
chassis).
c.
While
squeezing
together
the
latch
and
lever,
push
both
latches
up
as
far
as
they
will
go.
The
controller
slides
the
rest
of
the
way
into
the
bay.
12.
Reconnect
the
Ethernet
cables
that
were
disconnected
in
step
3
on
page
49.
13.
For
a
Fibre
Channel
RAID
controller
only:
Insert
the
SFP
modules
and
fiber-optic
cables
that
you
removed
in
step
4
on
page
49.
14.
Turn
on
the
storage
subsystem
if
you
turned
it
off
in
step
1
on
page
49.
Configuring
the
management
port
To
configure
the
management
port,
complete
the
following
steps:
1.
Open
a
Telnet
session:
v
For
a
single-controller
DS300
or
DS400:
Open
a
Telnet
session
to
the
default
IP
address
192.168.70.123.
v
For
a
dual-controller
DS300
or
DS400:
Open
a
Telnet
session
to
the
IP
address
of
the
active
controller.
2.
At
the
command
prompt,
enter
administrator
.
3.
At
the
password
prompt,
enter
your
administrator
password.
Note:
The
default
administrator
password
is
passw0rd
(all
lowercase
letters
with
a
zero,
not
O,
in
passw0rd).
Complete
the
following
two
steps
for
a
dual-controller
DS300
or
DS400
storage
subsystem
only:
4.
At
the
command
prompt,
enter
controller
peer
enable
.
5.
To
determine
whether
the
peer
controller
is
ready,
enter
controller
information
.
The
peer
controller
is
working
correctly
if
the
peer
controller
status
is
Ready.
6.
For
all
storage
subsystems:
When
the
peer
controller
is
ready,
change
the
IP
address
and
netmask
address
of
the
replacement
controller
to
match
your
previous
management
port
settings:
v
For
a
single-controller
DS300
or
DS400:
To
change
the
IP
address,
enter
interface
manage
eth0
ip
IP_address_of_failed_controller
To
change
the
netmask
address,
enter
interface
manage
eth0
netmask
network_mask_of_failed_controller
Note:
For
a
single-controller
storage
subsystem,
when
you
change
the
IP
address
for
the
management
port,
you
must
establish
a
new
Telnet
session
to
the
new
IP
address.
v
For
a
dual-controller
DS300
or
DS400:
To
change
the
IP
address,
enter
interface
manage
eth0[
x
]
ip
IP_address_of_failed_controller
To
change
the
netmask
address,
enter
interface
manage
eth0[
