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 code” on page 17 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 29). 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.
