CHAPTER
5
Adding or Replacing SCI Adapter Cards
If you add or replace an SCI adapter card on a node that has already been
configured by
sm_config
, perform the steps described in this chapter to initialize
the new adapter card.
Note -
Because the node has already been configured by
sm_config
, it should also
already contain
SUNWsci
and the other SCI-related packages. If not—that is, if you
will be installing these SUNW packages as part of the adapter card installation
process—perform the steps described in Chapter 2 and Chapter 3 instead, but only
on the node receiving the SCI-related packages and new adapter card.
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.
4
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.
4
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.
4
If installing a new adapter card that will be connected to an SCI switch, set its
scrubber jumper to ON.
