16. Reconnect all external cables and power cords and turn on the peripheral devices. 17. Restart the server, which should start up normally. Clearing CMOS If you need to erase configuration information, you must move the CMOS jumper. See the illustration in "Recovering BIOS" on page 18 for the location of the CMOS jumper. The default position is a jumper installed on pins 1 and 2. Before you change the position of this jumper, you must turn off the server and peripheral devices, and disconnect all external cables and power cords. Remove the cover and then move the jumper to pins 2 and 3. After moving the jumper, wait at least 5 minutes for the CMOS information to clear. Changing the position of this jumper erases all configuration and setup information, including the power-on and administrator passwords. Therefore, you must reconfigure the server after clearing CMOS memory (see Chapter 4, "Configuring the server," on page 33). If possible, record your server configuration information before moving the CMOS jumper. After you clear the CMOS information, move the jumper back to its normal position (pins 1 and 2). Reconnect the external cables and power cords; then, turn on the peripheral devices and the server. Replacing the battery When replacing the battery, you must replace it with a lithium battery of the same type from the same manufacturer. To avoid possible danger, read and follow the safety statement below. To order replacement batteries, call 1-800-772-2227 within the United States, and 1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call your IBM reseller or IBM marketing representative. Note: After you replace the battery, you must reconfigure your system and reset the system date and time. 20 Hardware Maintenance Manual: xSeries 200

16.
Reconnect
all
external
cables
and
power
cords
and
turn
on
the
peripheral
devices.
17.
Restart
the
server,
which
should
start
up
normally.
Clearing
CMOS
If
you
need
to
erase
configuration
information,
you
must
move
the
CMOS
jumper.
See
the
illustration
in
“Recovering
BIOS”
on
page
18
for
the
location
of
the
CMOS
jumper.
The
default
position
is
a
jumper
installed
on
pins
1
and
2.
Before
you
change
the
position
of
this
jumper,
you
must
turn
off
the
server
and
peripheral
devices,
and
disconnect
all
external
cables
and
power
cords.
Remove
the
cover
and
then
move
the
jumper
to
pins
2
and
3.
After
moving
the
jumper,
wait
at
least
5
minutes
for
the
CMOS
information
to
clear.
Changing
the
position
of
this
jumper
erases
all
configuration
and
setup
information,
including
the
power-on
and
administrator
passwords.
Therefore,
you
must
reconfigure
the
server
after
clearing
CMOS
memory
(see
Chapter
4,
“Configuring
the
server,”
on
page
33).
If
possible,
record
your
server
configuration
information
before
moving
the
CMOS
jumper.
After
you
clear
the
CMOS
information,
move
the
jumper
back
to
its
normal
position
(pins
1
and
2).
Reconnect
the
external
cables
and
power
cords;
then,
turn
on
the
peripheral
devices
and
the
server.
Replacing
the
battery
When
replacing
the
battery,
you
must
replace
it
with
a
lithium
battery
of
the
same
type
from
the
same
manufacturer.
To
avoid
possible
danger,
read
and
follow
the
safety
statement
below.
To
order
replacement
batteries,
call
1-800-772-2227
within
the
United
States,
and
1-800-465-7999
or
1-800-465-6666
within
Canada.
Outside
the
U.S.
and
Canada,
call
your
IBM
reseller
or
IBM
marketing
representative.
Note:
After
you
replace
the
battery,
you
must
reconfigure
your
system
and
reset
the
system
date
and
time.
