Rated. / 5. Based on customer reviews
Eclipse HX-Median CPU cards are fitted with a socketed battery, normally a Renata
CR2477N with a capacity of 950mAh and a life of approximately 247 days. These socketed
batteries are easily replaced and this operation does not have to be carried out by service
personnel.
Disconnecting the CPU backup battery
Before performing any service on the CPU card, the backup battery must be disconnected.
To do so, place the CON9 jumpers in the OFF position as described in the previous
procedure.

Table 5: CON9 Pin configuration
If the matrix is going to be stored for more than 3 months, 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.
Note:
Battery deactivation should be carried out by qualified service personnel.
Low power warning
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 in the
form of 2 rapid flashes followed by a slow flash of the OK LED. If EHX is logging, then the
following message will appear in the log.
Non Volatile Data is invalid - Please check Battery Voltage
If on successive power downs of the Eclipse HX-Median frame the above state is detected,
and the message appears in EHX logs, then it is advisable to check the health of the CPU
card on board battery, which should be nominally at least 2.8V.
The minimum at which the data may remain intact is around 1.5V but normally the battery
should be replaced before the voltage drops to this level.
