15. Place the board in its ESD safe packaging box.
16. Place the packaged IB_SSC assembly on a grounded ESD mat.
10.1.2 Installing the IB_SSC Assembly
1. Attach a wrist strap to your wrist. Connect the ESD wrist strap to the system.
See Section 2.8, “Antistatic Precautions” on page 2-6 .
2. Ensure the removable media cables are safely out of the way.
Caution – Do not force any board into a slot; it can cause damage to the board and
system. The board should insert and seat smoothly. If it binds, remove the board and
inspect the card cage slot for any obvious obstructions. Also inspect both the board
and the baseplane for bent pins or other damage.
3. Visually inspect the connector(s) for damage.
4. Hold the green side panels and gently insert the assembly into the grooves until
the antigravity clutch is engaged (
FIGURE 10-5
) .
The antigravity clutch holds the assembly into position so that it can be released
without the assembly sliding down into the system.
5. Push down slowly at the center top of the assembly until the top face of the
assembly is approximately three or four inches (7.5 cm to 10 cm) from the top of
the chassis.
6. When the assembly 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 assembly.
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.
7. Complete the seating. Lower the assembly using the ejector levers until the levers
are forced to approximately 45 degrees towards the inside of the assembly.
8. Reposition your grip on the levers and then push down on the levers to lock them
into place.
9. Install the I/O cards.
See Section 10.2.2, “Installing a I/O Card” on page 10-12 .
