If you intend to place the board in storage, putting the M48T58 in power-
save mode by stopping the oscillator will prolong battery life. This is
especially important at high ambient temperatures. To enter power-saving
mode, execute the 162Bug PS command (refer to Debugger Commands in
Chapter 3) or its equivalent application-specific command. When restoring
the board to service, execute the 162Bug SET command (set
mmddyyhhmm) after installation to restart the oscillator and initialize the
clock.
The MVME162P2 is shipped with the battery disconnected (i.e., with
VMEbus +5V standby voltage selected as both primary and secondary
power source). In order to use the battery as a power source, whether
primary or secondary, it is necessary to reconfigure the jumpers on J14
before installing the board. Refer to
page 1-10 for available jumper configurations.
The power leads from the battery are exposed on the solder side of the
board. The board should not be placed on a conductive surface or stored in
a conductive bag unless the battery is removed.
Lithium batteries incorporate inflammable materials such as lithium and
organic solvents. If lithium batteries are mistreated or handled incorrectly,
they may burst open and ignite, possibly resulting in injury and/or fire.
When dealing with lithium batteries, carefully follow the precautions listed
below in order to prevent accidents.
Do not short circuit.
Do not disassemble, deform, or apply excessive pressure.
Do not heat or incinerate.
Do not apply solder directly.
Do not use different models, or new and old batteries together.
Do not charge.
Always check proper polarity.
