ECLIPSE OMEGA INSTRUCTION MANUAL

1. Remove the desired blank rear panel by loosening the screws and pulling the
panel out. The screws are attached and cannot be removed.
2. Install the new rear panel by sliding the card into the card’s guides at the top
and bottom of the Eclipse Omega chassis.
3. Tighten all of the screws on the rear panel.
To remove a rear panel from the matrix:
1. Detach any devices connected to the rear panel’s connectors.
2. Loosen the screws that hold the rear panel to the matrix. The screws are
attached and will not fall off.
3. Remove the rear panel by pulling the panel out.
INSTALLING CPU CARDS
The CPU card’s components include CMOS chips which are sensitive to static
electricity. Before touching the CPU card with your hands, touch a grounded
metal object, such as any unpainted surface on the matrix, to dissipate static
electricity. While handling the CPU card, be careful not to bend any of the card’s
connector pins or component leads.
Before operating the CPU card, you must reconnect the card’s battery. The CPU
card is shipped with a disconnected battery to preserve battery life. For
instructions on reconnecting the battery, see “RAM Back-Up Battery” on pages
3-3 and 3-4.
Store spare CPU cards in unused slots in the matrix or in electrically insulated
packaging such as anti-static heavy duty plastic bags.
To insert a CPU card in the matrix:
1. Carefully place the card in the appropriate slot. Make sure the card is aligned
with the top and bottom precision guides.
2. When the card has almost reached the backplane connectors, open the two
ejectors, allowing them to clear the edges of the matrix. Gently insert the card
further until it touches the backplane connector guides.
3. Gently close both ejector tabs at the same time, which will propel the card into
the backplane connectors.
To remove a CPU card from the matrix:
1. Two card ejector tabs, located at the top and bottom of the CPU card, hold
the card in place in the matrix. To remove a card, open the two ejector tabs at
the same time until the card unseats from its backplane connectors.
2. Pull the card out of the matrix.
HOT PATCHING
The CPU cards are “hot patchable” and “self initializing.” When the matrix is
fitted with two CPU cards, a faulty CPU card can be removed and replaced while
the system is powered because the second CPU card will automatically begin
operating when the first card is removed. Sometimes, re-inserting a CPU can
reset the matrix. It is advisable to replace CPUs in maintenance down times.
