I/O Module Daughter Card

The server module board daughter-card connectors support a variety of dual-channel I/O module daughter cards, including a TCP/IP Offload Engine (TOE) NIC daughtercard.

•If installed, the daughter card must be used in conjunction with its appropriate back-panel I/O module and connector number.

For example, server module number 5 must have a Fibre Channel daughter card installed to communicate with the Fibre Channel pass-through module connector number 5 (primary and secondary bays).

•You cannot install daughter cards of different fabric types within a system.

For more information on I/O module daughter cards, see "Guidelines for Installing Connectivity Modules" on page 28.
