Figure 7-1: CPU card with detail of CON9 jumper plugs
Before performing any service on the CPU card the card’s battery must
be disconnected. To do so, place the CON9 jumpers in the OFF
position as described in the previous procedure.
Table 7-1: CON9 Pin Configuration
If the matrix is going to be stored for more than 3 months, or if the
power to the matrix is regularly turned off, the CPU backup battery
needs to be temporarily deactivated while the matrix is stored. To do
so, put the CON9 jumper in the OFF position as described above. In
order to power up and start operating the matrix, reconnect the CPU
backup battery by placing the CON9 jumper in the ON position, as
described above.
If the CPU card is left unpowered for a period of time the batteries for
the battery backed up RAM may become discharged. This results in
the run time information being lost. If this state is detected by the CPU
card then the CPU card will provide signalization on its OK LED in the
form of 2 rapid flashes followed by a slow flash of the OK LED. Also if
ECS is logging then the following message will appear in the log.
