The implementation of subtending is described in these sections:
• “Star Management” on page 48
• “Daisy Chain Management” on page 52
Each section provides both the features of and the limitations for implementing each subtending
approach. You can also combine the star and daisy chain approaches to effectively implement
subtending.

It is important to note that you cannot use the same card to subtend and be

to subtend another port on the same card.
