INSTALLING AN ECLIPSE
MEDIAN
RECONNECTING THE CPU CARD’S BACKUP
BATTERY
IMPORTANT : Before you install the Median you must reconnect the
CPU backup battery.
The CPU card has a lithium backup battery that powers the CPU
memory if the AC electricity fails. This backup battery is shipped
disconnected to preserve battery life. When you receive the matrix,
you must reconnect the battery.
The matrix will operate if you do not reconnect the battery. However, if
you power down the matrix you will lose all configuration information
stored in the matrix’s CPU card.
To reconnect the CPU memory’s backup battery
1. Please observe anti-static procedures. The CPU card can be
damaged by static electricity. Please ground yourself and tools
before handling cards.
2. Locate CON9 on the centermost upper portion of the CPU card.
Under the CON9 heading, there are three pins. A jumper plug is
placed over pins 2 and 3. This is the OFF position.
3. Lift the jumper plug off the pins, and place it over pins 1 and 2. This
is the ON position.
The battery is now powered.
On older Eclipse Median CPU cards the battery is normally a CR2430
3V VARTA 6430-701-501 and would be fitted on shipment. This has a
capacity of 280mAh and a life of approximately 73 days. These
batteries should only be replaced by qualified service personnel.
Later Eclipse Median CPU cards are fitted with a socketed battery
which is 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
presonnel.
Note: If the matrix is stored for more than three months, or if the
AC power to the matrix is regularly turned off (as in Outside
Broadcast vans), a qualified service person should be
contacted to disconnect the CPU backup battery before
storing the matrix. Only a qualified service person should
attempt to disconnect the battery. To contact a qualified
