Caution
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.
❏ Do not charge.
❏ Always check proper polarity.
To remove the battery from the module, carefully pull the battery
from the socket. (Data will be lost if a new battery is not installed
within 30 seconds.)
Before installing a new battery, ensure that the battery pins are
clean. Note the battery polarity and press the battery into the
socket.
Onboard DRAM
The MVME187 onboard DRAM is located on a mezzanine board.
The mezzanine boards are available in different sizes and with
parity protection or ECC protection.
Note Parity mezzanines are only supported on 25 MHz main
boards.
