Important Terms and Concepts

IMPORTANT In many cases, other interface cards and slots within the system are

dependent upon the target card. For example:

• If the target card slot is in a power domain and you temporarily stop

power to the target card slot, you will also stop power to any other

card slots (affected card slots) in that power domain.

• If the target card is a multiple-function card (MFC), suspending or

deleting drivers for the target card slot also suspends individual

drivers for the multiple hardware paths on that card).

During a card replacement operation, SMH performs a Critical Resource

Analysis, which checks the target card for critical resources that would

be lost when the card is shut down.
