4.1.3 Reconnecting the CPU card backup battery
Important:
Before the Eclipse HX-Median is installed, the CPU card’s backup battery must be
reconnected. The matrix will operate if the battery is not reconnected.
However, if the matrix
is powered down, all run time information (dynamic assignments, crosspoint states and
levels) will be lost.
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.
Observe anti-static procedures. The CPU card can be damaged by static
electricity. Personnel reconnecting the battery should ensure that they
ground themselves and all tools before touching cards.
To reconnect the CPU card’s backup battery:
1. Locate the three pins under the CON9 heading. A jumper plug is placed over pins 2 and 3.
This is the OFF position.
Note:
CON9 is located at the top of the CPU card, about half way between the front and back of the
card.
2. 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.
