If the start-up tests detect that the voltage level of a lithium backup battery on the
MCP-IPx or DBX card is insufficient to reliably maintain the memory contents in the
event of power failure, one of the following messages will appear:
MCP-IPx - BATTERY LOW
or
J1 DOWN BATTERY LOW
These messages indicate that the MCP-IPx card or DBX card battery has an insufficient
voltage level. The first message indicates that the battery located on the MCP-IPx 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 via the
database controls branch of the system database
(ROUTE: ROOT, 0, 10, 2, 2, 0)
. For
details, see
page 4-5, System Database Control
. If the system loses power or is reset for
any reason and the database is lost from memory, the system will copy the database
from the IMC8 card into database memory as the system restarts.
Once the system database is safely saved on the IMC8 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 MCP-IPx may be replaced and the system
restarted.
To replace the lithium battery, carefully raise the battery holder clip and then
insert the new battery with the + (positive) symbol appearing on top. Do not
apply too much pressure to the battery holder clip as this could cause the
clip to snap.
2 Memory Lithium Battery Condition Test
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.
