If the start-up tests detect that the voltage level of a lithium backup battery on the
MEX-IP2 or DBX card is insufficient to reliably maintain the memory contents in
the event of power failure, one of the following messages will appear:
MEX-IP - BATTERY LOW
or
J1 DOWN BATTERY LOW
These messages indicate that the MEX-IP2 card or DBX card battery has an insufficient
voltage level. The first message indicates that the battery located on the MEX-IP2 card has
an insufficient voltage level, while the second message indicates that the battery on a DBX
baby card (in this case, the card attached to memory connector J1) should be replaced. In
this event the Coral system database is in jeopardy of being lost during a power failure. If
this message appears, the database should be saved and the batteries replaced at the first
opportunity.
To ensure that the system database is not lost, save the database to the IMC8/IMC16 flash
memory card via the database controls branch of the system database (PI Route:
ROOT,0,10,2,2,0
). See
Chapter 4.3
of the C
ontrol Card Installation Manual
for details.
If the system loses power or is reset for any reason and the database loses memory, the
system will copy the database from the IMC8/IMC16 card into database memory as the
system restarts.
Once the system database is safely saved on the IMC8/IMC16 card, power to the Coral
system may be turned off at a time that will cause the least disruption of service to the
user. At that time, the battery (or batteries) on the MEX-IP2 may be replaced and the
system restarted.
To replace the lithium battery, insert the new battery with the + (positive)
symbol appearing on top.

Explosion and Environmental Hazards.
There is a danger of explosion if the battery is replaced incorrectly.
Replace the battery only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to requirements specified by the battery
manufacturer and/or local regulatory agencies.
