1. If a filler panel covers the backpanel SBus slot, use a #0 Phillips
screwdriver to remove the two screws and detach the filler panel.
Retain the screws to attach the SBus card to the backpanel unless the card
has a wide connector or set of connectors. See the SBus card installation
manual to verify the specific connector type.
2. Unlock the two standoffs for the slot.
Pull up the tip of a standoff to unlock it. See Figure 10-2.
3. Take the card out of the protective packaging and inspect the pins in the
connector to make sure they are not bent.
4. Guide the SBus card face plate under the springfingers and against the
rear face of the backpanel.
See Figure 10-5. The I/O connectors of the card should be visible through
the opening in the backpanel.
5. Hold the card by the edges nearest the SBus connector and place the card
over the two standoffs.
6. Firmly but gently press the card down until the connector is fully seated.
To align the connector and socket, push the card toward the system board
backpanel. Do not rock the card onto the socket; the plastic connector
housing may break.
7. Press each corner of the card to ensure it rests on the standoff flange.
See Figure 10-2.
8. Press down on the tip of each standoff to lock the card in place.
