Install/Replace SCI Adapter Card

Turn the node's power switch off and disconnect it from the power outlet. Note that this only needs to be done on the node receiving the new adapter card.

Check the scrubber jumper setting on the new card and change its setting if needed.

• If replacing an existing SCI adapter card without changing any other features of the network, simply give the new adapter card the same scrubber jumper setting as the one it is replacing.

• If installing a new adapter card that will be connected directly to another adapter card--not through a switch--set its scrubber jumper to the opposite of the other adapter card. That is, if the other card's scrubber jumper is ON, set this card's jumper to OFF. If the other is OFF, set this one to ON.

• If installing a new adapter card that will be connected to an SCI switch, set its scrubber jumper to ON.

If replacing an existing SCI adapter card, simply install the new card in the same SBus slot.

If adding a new SCI adapter card, install it in an available SBus slot. If possible, install the new card in the next higher slot. This will promote an orderly relationship between SBus slot numbers and network ID values, which can simplify network administration.
