Clearing Cmos; Replacing The Battery - IBM xSeries 200 Hardware Maintenance Manual

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
