3. Hold the green side panels and gently insert the L2 Repeater board into the
grooves until the antigravity clutch is engaged.
The antigravity clutch holds the board in position so that it can be released without
the board sliding down into the system.
4. Slowly push down from the center top of the L2 Repeater board until the top face
of the board is approximately three or four inches (7.5 cm to 10 cm) from the top of
chassis.
5. When the board is approximately three or four inches (7.5 cm to 10 cm) from the
top of the chassis, change your grip and grasp the ejector levers so that they are
oriented in the vertical position, 90 degrees straight out from the board.
Caution –
Metal pins on the underside of the ejector levers help to cushion the
CPU/Memory board after the antigravity clutch is released. If the levers are not 90
degrees straight out from the top of the board, there is a chance the connectors could
be damaged.
6. To complete the seating, lower the board using the ejector levers until the levers
are forced approximately 45 degrees toward the inside of the board.
7. Reposition your grip on the levers and then push down on the levers to lock them
into place (
FIGURE 11-3
) .
You can release the levers when the board is inserted halfway in order to change
your grip.
8. Remove the wrist strap.
9. Slide the system back into the chassis and secure it.
